Title: Interior lights
Message: You can turn interior lights on/off just like Rudz describe. The switch that turns the light on automatic when doors are open, are build-in to doorlock itself ( See Electrical manual page 24). Well, but I'm sure you all know that.!. Jørgen

Title: Damp Behind the Seats
Message: I was thrilled to find that my Elan was one of the very rare breed of "non-leakers". No matter how bad the rain, driving or stationary i could find no leaks from the hood. But this morning i found a damp patch in front of the rear speakers behind the seats? Cant work out where the water has gotten in while stood on my drive? What can i do about this and is it going to cause any other problems, THANX

Title: GGLC Track Day @ Laguna 4/9
Message: Speaking of track days--the Golden Gate Lotus Club has just announced the details of its first (of 4) track days for 2003 scheduled for April 9 at the legendary Laguna Seca reaceway. See their website: gglotus.org for details. The limit is 60 cars, and the spots are expected to fill quickly. And speaking (again) of roll bars--they are not required at this track so you don't have have to worry about having to design/fab/install one in the next month! See you there. Happy Lotusing, Joel

Title: Lowering Springs
Message: Hey all, wondering if anyone has used aftermarket stiffer/lowering springs on the Elan. What were the Spring rates etc? Feedback please! Ive tried to get hold of Dave Schmid who did the entire set up, but havent got a response. I am looking primarily for the rear as I have the GAZ adjustables on the car and want to use Lotus Stock in rear with Lowering/stiffer springs.

Title: Leaks
Message: Ryan, was the car left pointing up-hill? The water can run under the door, get past the seal and then build up until it leaks over the plastic sill-cover and behind the seat. Does that sound likly?

Title: Jorgen's in-process shots
Message: Interesting photos of your restoration! The front end status looks similar to what is sitting in my garage (Monaco White and all!). One thing I did find interesting is the radiator and a/c condensor appear to be standing upright. On the US car, they are at approximately a 45 degree angle leaning back due to extra material for 5 mph crash standards. We have a honeycomb-type aluminum crush piece sitting directly behind the front bumper. This gave me fits in trying to stuff a FMIC in there. Looks like non-US owners could use more than the 8" tall intercooler I ended up going with.

Title: Proportioning Valves
Message: Yesterday, I installed the new proportioning valves I purchaised from SJ Sportscars. I remind you thet Steve @ SJS was extremely helpful and the package was delivered to me in under 3 days from the time of ordering !!!! So the only thing to discuss is how the brakes work! I only drove my baby for not more than 10Km in traffic jam, so I cannot say much, but I can say that the feeling is the same (more or less expected) and the braking was also the same (not expected). Maybe I comment more after some days of braking oooops driving!

Title: Chris Brown's IC
Message: Pictures of Chris Brown's intercooler are available here: http://www.informatica.zen.co.uk/elan/ic Apparently the IC came from a Rover 220 Turbo and the nice pipework was a custom job. From the looks of it, the IC is mounted in "serial" to the standard IC, and the inevitable pipe run could induce slightly more turbo lag I suppose. Obviously the standard airbox was removed to make space. One thing that is interesting is that the turbo air intake will get warmer air from the IC, this warm air then gets sent through the std IC, then the new IC, getting cooled by the colder air that is normally fed to the airbox, before going on to the intake plenum. Sort of circular cooling effect...

Title: New to the Elan
Message: Hello all, Just wanted to ask a couple of questions and since you all seem a friendly bunch thought I would take the plunge, I have just posted on the elanscan message board. (possibly in the wrong place) so thought I should post here too. I have a 91 Elan SE Turbo, that currently is standard, however I am having a couple of small problems that I thought you might be able to help with, I have spoken to D Massey at Lotus and although he was helpful he seemed keen for me to take it to the dealer (unsurprisingly) where I really want to try to do the work myself (after all thats why I bought the car!) okay firstly the car seems to be producing VERY low stock boost. around 0.4 Bar the engine is mint and of very low mileage and the previous owner tells me that it has always produced that amount of boost (but then he only had it sine september!) in addition to this the intake pipe from the inlet manifold seems to Squeeze itslef together when revving from inside the engine bay, could this be a blockage in the system somewhere? I am having the Bailey motorsport Dump Valve fitted on Friday and am planning to build a MBC soon afterwards but would really like to solve this problem beforehand. Secondly I am experiencing a strange problem with the revs of the car, it seems to Idle at around 1000-1200 RPM at most times, but sometimes when it is cold much higher, and at times it sticks at around 2,200rpm. According to Lotus it should be sitting at around 950rpm. Also when it idles high it seems to absolutely drink the fuel and throw out more smoke from the exhaust than is usual (especially when its cold) which would lead me to believe it is overfuelling. unfortunately I believe that my temperature sender unit is broken as it never gets above cold so its difficult to diagnose if the problem could be the ECU temp sensor! Again, anyone got any Ideas??? Thanks so much in advance

Title: Sean
Message: Welcome to the site, and congrats on the Elan. We'll help you sort it out. Sounds like it could be a few things; but first question is: do you have a laptop? If so I'd recommend you download the ElanScan program and get a cable to run it (see links in ElanScan area). This program will read all the car's sensors, boost, ignition, etc and is a worthy investment for a DIY type! This will show you if a sensor is bad for sure. You could also have a sticky wastegate actuator rod or a non-functioning boost solenoid valve (BSV) as the stock wastegate is actually 0.4bar, and only with the BSV working will it go up to 0.65bar. But the idle thing seems to be something unrelated, maybe a bad Coolant Temp Sensor--you could check this with a multimeter if you had to but I did that before and it is not very precise that way.

Title: Low temp.
Message: It seems that I'm not the only one who suffers low temp. When driving in -2C deg., it is almost impossible to get the heater going. I have changed the thermostat -didn't help, tried block of half the cooler, a little better, but the gauge still shows almost nothing. Has anyone a good idea on how to solved this problem. Jørgen


Mar 4, 2003 - 15:08 - From: Dave M.
Title: Sean - BSV
Message: I'm with Doug on the boost solenoid valve (BSV). It's the small, round, clear-topped unit that sits behind the air filter canister. It will have hoses coming out of it. Check to make sure they are connected - one to the turbo compressor outlet, the other to your intake pipe between the airbox and the turbo. I forget (as I've had my BSV removed a while), but I think there's also a third leading to a vacuum switching value - a blue-topped piece mounted in the right hand side of the engine bay, near the airbox.

Title: Temperature
Message: Jorgen, normally my temp. gauge shows at 1/4 the way up when running at cold temps, but we just had the coldest winter in 7 years here in Florida and during these cold times my gauge would run like you said, just a tick above full cold. I too thought the thermostat was bad and changed it to no effect. What gives here? It does not seem to make the car run poorly though. I too would like to hear what further owners have to say.

Title: Bye bye Isuzu?
Message: Quote from page 42 of the April Motor Trend magazine, "Speculation is rampant that Isuzu will have to pull out of the North American market within a year". Get used to paying those Lotus prices or stock up wisely fellas.


Mar 4, 2003 - 15:59 - From: Matthew Welsh
Title: World's best intercooler!
Message: From page 40 of April's Motor Trend magazine. The current Ford F-150 Lightning concept uses an additional evaporator (this is the part that goes inside the cab of your car under the dash that air blows through to get cold, right as the R12/R134A is turning into a gas and absorbing heat) in the A/C unit and locates it in the engine's intake tract. It is activated whenever the driver activates wide-open throttle or presses a button on the dash. Ford calls it the "Supercooler" and says it raises the engine's output by 50HP. The engineers point out this is done simply by taking advantage of the hardware that already exists in the vehicle. "One of a blown engines dirty secrets is that they don't maintain their rated horsepower when used in heat-generating conditions."


Mar 4, 2003 - 16:42 - From: Laurence
Title: new to Elan
Message: Sean, I wonder if you have a hose collapsed internally between the Turbo/intercooler/throttle body or have a clogged up air filter, or one of the 1/4" BSV hoses Dave described is blocked (it's just the 2 by the way)? These would be simple things to check yourself. If the hose from the Turbo (wastegate actuator) was pulled off from BSV then I think you would actually have a constant bleed and the boost could zoom up to about .9bar and the ECU would cut the fuel supply off (a bit dangerous and not recommended but you would find out if it was the BSV or not!). I'm a bit rusty on this but if I remember correctly, with the ignition off the BSV is closed but it should start to open as you approach 0.4 boost until it then starts to cycle open and closed to hold max boost at 0.65. The boost gauge on most standard cars never seems to get much over 0.5 anyway but you should at least get there. Good Luck Laurence

Title: Low temp
Message: Mine's very similar in sub zero (talking deg's C) conditions but after about 20 mins driving it starts to come up a bit and I start to get a medium amount of heat out of the heater. Not enough to take the hood down though! I think the secret is to get put your foot down and work that Turbo (a bit difficult if the road's are icy though) - Laurence


Mar 4, 2003 - 17:33 - From: Paul
Title: Temperature
Message: I live up here in the Northeast USA. While I store the car during the winter, I get it out monthly to exercise the AC and bring the engine up to full temp. I have had no trouble doing so. In fact, if left at idle, the guage goes all the way up to 3/4 and cycles the cooling fans on. The temperature is well under freezing when I do this. I think this is the proper design of the engine cooling system. If the engine is not coming up to temp, there are really only a few causes - thermostat not working properly, guage defective or perhaps a wiring problem of some sort.


Mar 4, 2003 - 17:57 - From: Matthew Welsh
Title: low temps
Message: Car works fine as you say when left to idle in the drive. Temp goes to 3/4 and fans come on then cycle normally. But if driving (moving) in the really, really cold stuff the temps stay lower than 1/4.

Title: Looking for previous owner...
Message: Are any of the Southern California owners around here (and you too Doug) familiar with anyone that would have owned a BRG Elan in the Lancaster area during the '90s. Title was reissued in January of 1996 so I'm guessing that is when the original owner sold it to the person I bought it from. The guy I bought it from claims to know nothing about the mods and they were done by the original owner. Mods include Garret turbo, EBC, custom intake ducting, BOV, etc. What I'm trying to find out without taking the intake off is if the owner also went for upgraded (larger) injectors. Also, if those who have done the injector change out thing can tell me, is there a visible difference from the stock ones just by lookin at the visible part of the top without pulling them? Thanks much...

Title: Low Temps
Message: I've been driving my Elan throughout the summer here in Australia and have had similar results. If left idling the gauge gets up to the 3/4 mark quite quickly. However, once the car is moving it drops to 1/4 or slightly lower. This in temps as high as 40C.

Title: Its all making sense now.
Message: Just got my elan back from lotus service centre (christopher neil) - had full A+C plus cambelt service. Unfortunately three unwanted problems have arisen. Firstly the Revs are sticking at about 2K when idling. Secondly the boost is only going to .4 where is was going up to .65(stock btw). and lastly the switch that changes airflow in the car to windscreen, feet etc (don't know what its called) is not working - just get very hot feet now. I cant see how this last one would be related to the service but i've no way of demisting the car now! - Not happy with Lotus at all right now!

Title: Airflow Switch
Message: Ryan, there is a strange connector right behind the switch that must have been disconnected. You can reach it with your hand by removing the cover under the steering wheel-column (not the steering wheel itself). Be careful to connect it properly and test it before screwing the cover back, because the connector is really strange and you can easily make mistake.


Mar 5, 2003 - 05:36 - From: Laurence
Title: Air flow switch
Message: Ryan, in addition to what Dimitris said, first check the vacuum pipe that operates the flaps. You will find it behind the glove compartment and also connecting to the throttle body (left hand rear corner - looking from the front)- could well have come adrift. At least you have heat - don't complain! Laurence

Title: Further with my elan
Message: Yes I do have a laptop, and Im in the process of connecting up the circuit as we speak. However back to the BSV on the turbo I checked mine and there only seems to be one hose connected to it, which appears to be coming directly from the wastegate. Below the bsv there is a nozzle which feels as though it should house a hose, however I am at a loss to locate where it could be, so any help here would be MUCH appreciated. Also.. How the hell do you get to the temperature senders with the damn CAS in the way? Is it pretty safe to remove the CAS as long as I mark the position it was set at? How safe is it to fit this MBC? I'll have the blow off valve by friday and wouldn't consider it before then but I'd love the extra power if it was relatively safe. And finally with regards the high idling etc, having a wiggle with the leads seemed to sort it out quite a lot, but until the car is "really" warm it does seem to overfuel causing quite a lot of white vapour from the exhaust, any ideas??? Thanks again guys

Mar 5, 2003 - 09:20 - From: Laurence
Title: Further with my elan
Message: Sean, the other hose is one of two that connects at the point where the turbo intake hose joins the airfilter box. You must have one hanging loose feeding unfiltered air to the Turbo! Check here for an MBC a lot of us use: Rob C installation details are here on Rod's site: www.mardibloke.co.uk/Cars/Lotus_Elan_M100/Upgrades/Rob-C_Boost_Controller/rob-c_boost_controller.html This can be used in place and instead of the BSV so if your BSV is faulty it's a cheap fix! I would then keep your boost to about 0.75 on the gauge, this is in case it reads low - at .92 the fuel pump cuts out (unless you get a fuel cut out defeater - FCD) Laurence


Mar 5, 2003 - 10:38 - From: Doug
Title: CTS
Message: Sean, the CTS is tight behind the CAS. You can disconnect the rubber-end electrical connector from it to test the resistance without moving anything--just be sure the engine is not too warm! If you are going to use ElanScan then just wait to run it to read the CTS and other sensors if your car is running okay. Maybe think about new spark leads if you meant they are on the fritz--SJS has some of the Magnecors for a good price. Consider they are over 10 years old, and could have over a Billion sparks fired thru them if you have enough mileage! The turbo hose routings are pictured in the manual pages you can get to from a link on the "repairs" section.

Title: lo temp
Message: I think the thermostats they sell now are a few degrees colder than original. [180 instead of 185 IIRC] I switched to a 190-195 thermostat and it is much happier, runs at 1/4 instead of a tick over low. Plenty of heat. all cars will get hot in the driveway, but if the thermostat is dead it will cool off as soon as you hit cruising speed [brrr]. I am keeping a 180 deg thermostat in reserve if it seems to run too hot in the summer

Message: Nice looking car, Karl (I'm partial to the white!). Did you replace the strut assembly to lower the car like that or just install different springs? I'd love to get that on the track with center of gravity lowered a few inches! Did the seats go in fairly easily? Did you have to permanent mount them or are they on sliders? Did it raise the seat much from stock? After looking at the way your shoulder bolsters curve in, there may be hope to stuff a few seats in mine with my rollbar!

Message: Spot on on the hose guys, the previous owner had left it dangling at the back of the engine and I hate to think of the sort of crap it was sucking in. It's now connected back in its rightful place! Idle problem turned out to be a sticky throttle position Switch as a blast of wd40 and a wiggle ahs sorted that now too. However Im still having the problem with the whole temperature of the car thing. I'll get the ElanScan logs on as soon as possible. A big thankyou to everyone for helping me with this.

Title: High idle
Message: Hi Since modifying my engine with a K+N filter, MBC, HKS dump valve and fuel cut defenser the increase in performance is great, unfortunately the idle speed seems to have increased from around 800 RPM to around 1200 RPM. Any ideas???


Mar 6, 2003 - 17:07 - From: Ryan
Title: Mileage
Message: I'm sure i'll get a lot of replies here But this is a question that should help everyone. SO, How many miles should i be getting on a full tank of fuel - urban and motorway. I'm getting well below 200 miles on a tank and by my calculation that is no where near what the spec sheet says?


Mar 6, 2003 - 17:20 - From: Doug
Title: Shaun's Idle
Message: None of those additions should inherently change the idle speed, EXCEPT that fuel cut defenser. It may be sending an errant reading to the computer, as I assume it is a modified MAP sensor circuit. I'd recommend you remove it/replace it to normal if you can and that should rectify the idle issue (to prove that is the culprit). If you were running the ElanScan program you could read the MAP readings/waves/curve and see if it is correct! Can you check the output voltages of the MAP on a bench type set-up?

Title: Re: Mileage
Message: I get ~290 miles per full tank, driving 'vigorously', mostly freeway. More than once, with the gauge showing just under 1/8 tank and the fuel light on, I've experienced fuel starvation on a 360 degree offramp, and head right to the station.

Title: headlights
Message: has anyone ever experienced dipped beam headlight glass on both sides shattering? They both seemed to go at the same time and the full beam lamps are ok. It can't be down to stone chips or vandalism as I haven't been driving at night - could they be staying on and overheating or could it have been when I hit a pothole and the glass hit of the inside of the pods. It's just the lenses that are shattered - the bulbs are ok.

Title: HiSpec Brakes
Message: Guys, I don't want to kick off another big discussion on brakes, nor do I want to tempt 'Lead Eater' into praising the original set up again (maybe he designed it, hence the big defense?!). Anyway - my question is - has anyone used their HiSpec brake system on a track day? How did they perform when really hot etc?


Mar 7, 2003 - 11:28 - From: Rod
Title: Hi Spec on track
Message: Yes. I have used the standard Lotus setup, then Tarox discs, various pads, braided lines, and fluid changes. For 2002 I had Hi Spec 285mm EBC grooved discs, four pot calipers ( no dust seals ) and DS2500 pads. I run standard 15" wheels. I am pretty sure a big problem on standard calipers is they just cannot get rid of the heat. Someone should really try ducting air in, as you can pretty easy get a long pedal and brake fluid that needs changing every track day. Changing pads, discs, and braided lines, make it fine for hard road use, but still on track the calipers overheat. I never warped my Tarox discs, but know people that have warped ATE and EBC discs. Spending the money on Hi-Spec is not really worth it for road use IMHO, but on track you can stay out for longer sessions, braking is improved, finally I was getting some heat into even the rear brakes and I have not had a fluid problem. Biggest gain is on circuits with multiple high speed stops ( eg Donington full circuit ), as the brakes just keep working. Only problem I have is that I warped a disc with the Hi Spec setup, and would like two piece discs which they don't do. Hope that helps.

I think that my temp gauge may actually be okay as my elan does not seem to be getting very warm at all. the heaters blow out warmish air, but by no means hot. Has anyone experienced this and have a possible solution? I live in the UK and its pretty cold here so I may be just being obsessive, but better safe than sorry. Just had the Bailey Motorsport dumpvalve fitted. And its a great mod. Thanks for the advice. Sean

Title: Temp
Message: Sean, your Elan sounds like it basically performs like mine. When sitting in traffic it'll go to 3/4 then the fans cut in. When driving around in 'normal' temps (ie: 10 - 25 degrees-C) it'll sit around 1/4. The heater will not give out much heat at any time I. But during really cold weather like we've just had I find that the temp will hardly rise off the bottom, even after half hour on the motorway. I suspect that the main reason that the temp rises so fast when sat at tick over is that the water pump is running too slowly to get the water around the radiator. I did a test on the motorway - running down the M1 at 100mph for several miles (temp sat on 1/4), then I just put the car in neutral and let it coast. Within one minute or so the temp gauge had started to rise, and I was still going at a fair pace. So I deduce that it is not lack of air through the rad, but lack of pumping through the rad. Comments......?

Title: Hi Spec on track
Message: Andrew, I back up what Rod says: even uprated discs and pads in the standard setup can't cope with track demands. I managed to basically melt the whole of my standard braking system on an airfield day, which places higher demands on the brakes than a typical track day. This led to the immediate quest for uprated brakes, and since finding and installing the Hi Spec setup I've not experienced any fade on track and much more stopping power. I too have had a disc warped when I let a friend drive, but he did abuse it terribly (locked the wheels and then tried to steer round a chicane with the wheel still locked, wrenching the wheel from side to side...imagine the forces acting on the disc)

Title: Too cold!
Message: Not put a message up before so hi everyone! -have owned my Elan for over 3 years, and just fix stuff as it goes wrong. Sean -I could never get warm air, especially on motorways and the gauge was well below the 1/4 mark - turns out the thermostat was faulty (stuck open) cos after about a year of running the car it then went and stuck closed, and overheated with coolant shooting out of the reservoir! It was quite a surprise to get really warm air too, once fixed, even in the UK winter! For about £10 and 30min its worth a try.

Title: cooling fans down !
Message: this morning both my radiator cooling fans decided to take a break from their normal duties & as a result, temperatures shot up immediately. i have checked the radiator thermal switch on the thermostat housing. the fans themselves are ok. the 2 fuses for each cooling fan (in the top dashboard) are also good. does anybody have any ideas on what might have gone wrong or what else i should be checking ? does the air-con pressure switch have a reputation for failing ? Doug, would ElanScan help here ? cheers ... rudz

Title: cooling
Message: I agree with Nick on the thermostat! Mine (in hindsight) was cracked open a hair for about 6 months allowing the car to run too cold on the highway--when I exited and stopped the car would run on the high "cold idle" setting (clue to think about). Then it stuck closed and I almost overheated it! So if your problem is too cold you should know that our thermostat has a nasty habit of slowly failing like I described!! Rudz, if your t-stat fails closed, hot coolant will NOT get past it enough to engage the fan thermal switch--you need to know this switch is on the "far side" of the t-stat!!

Title: HiSpec
Message: Being cheap now - could I get away with keeping my EBC discs and installing new Hi-Spec calipers? Or does a lot of the added performance come from the larger diameter discs?


Mar 7, 2003 - 13:36 - From: Rod
Title: Hi Spec with standard discs
Message: Good idea Andrew, and the Hi Spec mounting bracket might put the caliper in the same place, but even if it did, you will need new pads to fit the caliper and these have a bigger pad area, hence will overhang standard discs. Not good for the discs or pads. Suggest you wait until you need to spend money on new discs / pads, and then consider the Hi Spec option. You could also see if there is a Willwood kit available for Elan and price that up.

Title: Bills Upper Intercooler pipe
Message: I just received Bills Upper Intercooler Pipe the other day. I assume the install is pretty simple but I am not sure exactly where to connect the hose that comes off the HKS blow-off valve or the small pipe coming out the side of the blow-off valve? Can any one help, or point me in the right direction?

Title: cooling
Message: Things have warmed up and my car is back at normal low temps now. I was going to hold off changing the t-stat until next winter. However, now that I know the early warning sign I will change it within the next couple week(ends). What I can add now is that you can play with your fan thermal switch without changing the t-stat or your coolant. The trick is this: I have all 3 different thermal switches now and I played with them all to see their effect. What you do is jack up your car fully in the FRONT only and wait until your car is entirely cold. At that point you can loosen the overflow-tank cap enough to depressurize your cooling system. This will allow you to unscrew & remove your thermal switch with NO coolant leakage because your t-stat is closed and even though lower than your overflow reservoir will not let any coolant past to escape out the gaping hole created by the removal of your thermal switch. What a joyous thing to discover!

Title: Bills Pipe - the connections
Message: I just took a couple of pictures, which say a thousand words : http://WWW.MARDIBLOKE.CO.UK/pics/billspipe/index.htm Depends which Dump valve you have, but worth doing the connection from dump valve to bills pipe if you have that option, else leave it blanked off on the pipe. Other connection can be t-piece into tube that goes to boost sensor ( red thing on left inner wing ), but better IMHO, is that there is a blanked off connection that Rob C spotted. You can just about see it in the last photo, and it will be obvious when you look for it.

Title: Extra air intake
Message: I had a thought for an extra air intake (if it would work - and I've not pulled the car apart to check) for front caliper cooling or an extra intercooler. You know where the front air filter fresh air intake is above the intercooler on the left side, well what about replicating the same thing on the right (oil cooler) side and then running a flexible air hose from inside the wheel arch liner to wherever it's needed? Perhaps folks who are familiar with that part of the car could comment? Laurence

Message: Further to the ideas of using the round Esprit or Elise type lights in a special mounting for the Elan. I'm not that familiar with these units but I was looking at some pics today and it seemed to me as though this units might not include rear red reflectors.

Title: brake cooling
Message: Laurence, good idea on the ducting, however you'll want something that will pick up a fair amount of moving air. The stock air intake pickup is behind a small 2" x 2" cutout in the back of the headlight pod. I don't think you'd get enough air through there to notice a difference. Though if you willing to do some cutting that might not be a bad place to draw from. I've got the whole front end off my car and am trying to put something together that will fit the stock setup. Dave Schmidt also did some ducting and I think he may have just hung the opening of his down into the airstream under the car...probably the easiest way. In dreaming of upgrades for my wife's car I came across these. http://www.bmwe34.net/e34main/upgrade/540_ducts.asp They would look neat on her car, though she'd never need them. I've thought of having a go with the Elan to see what I could make work. Worse case, I'd have to put them on the BMW! Darn... :)

Title: brake cooling
Message: Dave, on my car, which does not have air con by the way, (looking into the left hand front grill with a strong light) there seems to be a 2" dia circular air intake in the top (extreme left) of the recess in front of the intercooler. I was assuming (hoping) that there must be a ram effect providing a good air supply to the filter. That's why I thought (assuming you can get to it) you might pick up a decent flow of air if you could do the same kind of thing on the other side of the car.

Had our first nice warm day here on Sunday and it was great fun driving the elan with the top off. Unfortunately experienced a minor mishap involving a speed bump and a great big hole in my exhaust system. :-( However all is not lost, I have been in contact with Janspeed in the UK who still have the Jig for the Elan SE Turbo and as such are more than happy to knock an exhaust up for me out of mild steel!!!!. Just as a side note here, if anyone else wants to get one made up (including you guys in the US) then I have a great contact there and although they don't ship to the states I can get it sent from work if you would like.

Title: Fuel Consumption
Message: Ryan, Geoff are either of you getting any other symptoms? Bogging down on acceleration, smell of gas, or any signs of running overly rich? I'm curious in that I'm in the same boat at the moment. Only getting around 200 miles per tank, though I'll admit that is mostly city driving. However I know I'm running rich to the point that it bogs down under load if you give it too much gas too quickly. I'm still trying to determine what is causing it. All my sensor readings look good, at least to me, in ElanScan. I've got new plugs, wires, O2 sensor, and fuel pressure regulator. Looking at the fuel mixture in ElanScan, the only time it drops from 14.7:1 is when it's under high levels if boost at WOT. Need to recheck but I don't think it's dropped below around 11:1 even then.

Title: Fuel consumption
Message: If you have an SE the check the CO potentiometer voltage. The air fuel ratio is predicated on a properly calibrated CO pot. The nominal value is 2V - if the car is still rich at 2V, and there is no other fault, then the CO pot. needs adjustment. My own fuel economy is not great (about 260 miles a tank) but it 200 miles when I got the car. Two things helped, a adjustment to the CO pot (done by a man with a Tech 1). and an exhaust with a bit less of a squash in it! The latter probably had the greater effect. Ed, Don't treat the air fuel ratio as a diagnostic tool - its a target value not a measured one - check the oxygen sensor value is averaging around 2V.

Title: Thermostat and MPG
Message: Since changing my thermostat out on your advice I have seen a definite improvement in the Mileage I have been getting from the car, it seems to come out of "cold" mode much faster, the exhaust gas quickly clears and the throttle response and idle all seem MUCH better. If you chaps are suffering from a similar temp problem perhaps your thermostat could also be at fault, or failing that perhaps the temperature sender could be faulty, ElanScan should help you diagnose that, I'm easily getting an additional 50 miles to the tank since the replacement thermostat though, so worth a look!

Title: rough running
Message: Sean, sounds like you got it fixed up! Ed, sounds like you are still not finding the problem. I remember you have done a pretty logical and thorough investigation and have even checked ElanScan for problems. I remember you have a turbo upgrade with EBC but otherwise are using stock sensors and ECU. The thing I wanted to say is that it sounds like it could be the CAS acting up--I can't remember if you changed it but I hope not yet. I had a nagging little problem and I used ElanScan to investigate--it confirmed that nothing else was to blame and ruled out the obvious offenders, and from the symptoms I therefore "guessed" it must be the CAS--replaced it and all is great since. The point is that even with normal ElanScan the CAS could be acting up. I cannot think of anything else reasonable to check other than real weird things like piston ring seals, a bunk injector or other far out problems--but then you don't have clear symptoms of these either. Might be worth getting a new CAS to see? Anyone else have ideas?

So, after a second bleeding, 100 Kms from the proportioning valves' changing, the feeling of the pedal is great! The breaking is also great and you feel like you throw an anchor! I remind you that I have changed the breaks to EBC disks/greenstuff (front) and just black pads (rear) and Goodridge braided hoses. But there IS a disadvantage, comparing to the last set I had - just some drilled and grooved disks and greenstuff pads : On continuous hard breaking (when on track day) the breaks seem to get hot and tired, and the feeling AND performance gets much worse, something that NEVER appeared with the last set. This is quite strange, because everything seems to be enhanced!!!

Title: Various replies...
Message: Doug, I've done the resoldering of the hall effect sensor thing but I've not completely replaced the CAS. I am also starting to think along the lines of leaking injectors or possibly an ailing fuel pump. I've been thinking about getting a fuel pressure gauge to install as it would help with making a determination on the pump and wouldn't be a bad thing to have if I ever go the route of trying to push the thing to the ultimate usefulness of the turbo the first owner dropped in. I also find Sean's comments interesting as I know I am running a 180/82 degree thermostat. I put it in as the old one froze open shortly after I got the car. I doubt I checked mileage before then as I was mostly using it for fun runs and autocross. Alan, thanks for the mixture info, I wondered if it was just an ECU target value I didn't think there was any sensor beyond the O2 sensor to pick that up. Also, does the US SE have a CO pot? I didn't think ours did. If so where would I find it? I think that about covers it...

Title: Hi & upgrades
Message: Hi, It seems there are a lot of happy any very keen Elan owners here. I have had my 1990 Elan SE now for 3 years and love it to pieces. Recently I have considered giving it a second lease of life with some upgrades. I have spent too much time reading various websites recently. This is what I think I can conclude: Pls comment. The plugs leads and filters all seem simple. However if i go for the fully mapped unichip with boaster do I still require the dump value. Illustrated on Philbo's site? Replacing my ageing exhaust with a complete stainless steel system seems logical, any ideas on the best source (performance and value? There is a stainless steel system at SJ sports (site) for about £200 and I have been quoted £424 (including fitting and Vat) for a custom stainless steel system with a promised 8-12 bhp. Brakes will require performance front discs and pads (road use only). Will the above a) be safe to drive? b) deliver 200+ bhp in a non stressful way to engine? I am already guessing it will be even more fun. I am based in Berkshire so localish suppliers would be helpful. Warren

Title: Upgrades
Message: Warren, yes plugs leads and filters all simple, as is installing a dump valve, which is almost recommended regardless of state of engine tune as it saves wear and tear on the turbo. A new exhaust will only give you extra bhp if it is less restrictive than the stock system (not hard), but it is mandatory to release all of the stock Elan's potential. Finally hold fire on the Unichip...there are some issues fitting these to the Elan as they are designed to work from standard crank signals which the Elan doesn't provide! However today I spoke to my people and they are going to go ahead and fit it to my car by basically working out how to make it all work...we've both given up on waiting for Dastek (who make the Unichip) to provide us with the technical info we need. The new schedule for this is now sometime in April.

Title: CO potentiometer & economy
Message: Ed, S2s and US spec cars don't have a CO pot - they operate mostly in closed loop mode where the oxygen sensor reading is used to modify the mixture to the optimum. When you boot it and the mixture goes rich and open loop mode kicks in - I don't know how you would alter the mixture in open loop mode in a catalyst equipped car or even if its possible. If you have a leaking fuel injector then one cylinder would run lean and knock would occur - do you see much activity in the knock counter? If the fuel pump has low pressure you might see a higher injector pulse width than a unaffected car - hard to compare directly, I know, but worth checking for obvious differences. I reckon Doug might be onto something with the CAS - I had minor CAS problems (not enough to put the check light on) that caused hesitation - particularly at mid revs and high throttle as well as very occasional cutting out at idle. I fixed it with torquemaster plugs but it was treating the symptoms not the disease - I did get the check light in the end. Also have you checked the timing?

Message: Thank you Philbo & Sean, I will wait to hear about the unichip and the Janspeed exhaust. When I fit the dump valve do I also need to remove the boast limiter? If so how is this done? Thanks


Mar 12, 2003 - 05:45 - From: Philbo
Title: Dump valves
Message: Hi Warren, the dump valve is an independent item so you do not have to worry about installing boost limiter options at the same time. Your options there are the typical MBC as described on this site, or some more sophisticated cheap electronics which will fool the ECU into allowing more boost.

Title: headlights
Message: hello folks, I've worked out what happened to my lights. they shattered because after changing the bulbs the other week i (stupidly) tightened up all the screws surrounding the lamps including the sprung loaded ones for adjusting the beam angles. this has left the lamps rigid in the pods and when i hit the pot hole the sudden jolt has smashed them. i think ? the headlights that i bought at donny were federal(lhd) but at £6 a pair they got me home (worth it for the bulbs alone). this still leaves the problem needing headlamps that work and will pass an m.o.t. it's the outer dipped beam lenses that have shattered and chris neil want £140 quid for a pair. are the lamps interchangeable with any other cars or can they be upgraded (coz there not that bright) and how much for? p.s nice to meet so many nice folk at donny, there was a helpful exchange of info and experience and i will be back next year. cheers, stephen.

Message: I have one replacement UK headlamp unit I can sell you... I bought it rather unnecessarily some years ago for an obscene amount of money (about £80 as I recall - would take 40 or so). But from the sounds of things you need two of them. You can also get them for about £52.50+VAT from SJ Sportcars it seems (http://www.sjsportscars.co.uk) which is a little bit less than you are being quoted.

I may go ahead and order a CAS just to give it a try. Anecdotal evidence gives that as high a likelihood as anything else at the moment. And given the history of the CAS for the Isuzu engine in general, if it's not the cause, having and extra on hand wouldn't be a bad thing either...

If you go for standard Lucas (or Cibie) H4 type dip/main units you will need to alter the connector and wiring (I think they can supply a plug in loom mod). Laurence

Title: Sticky Boost Gauge
Message: Any one experienced a boost gauge that refuses to return to zero? Regardless of my efforts to dislodge it my thumping on the top of the dash, my gauge continues to dify the laws of gravity and stays at .25 bar or just under. It does however rise ok when the boost level increases, although it has hit 1bar a few times on hard acceleration (mbc currently on minimum). Am I to assume that the gauge is at fault or the sender unit?

Title: Sparkplugs
Message: Is there anyone out there who has experimented with different sparkplugs? I'm currently running an S2 with a MBC with just a moderate increase in boost (gauge measures 0.7'ish on max). I am experiencing hesitation under higher boost conditions. I have tried reducing spark plug gap on existing NGK plugs which marginally improved under boost but engine ran less smooth at lower town speeds. A local garage to me sells Splitfire plugs but has warned that these can overheat and cut out in turbo cars. With the price of a set of these platinum plugs at around £40, it's a bit much to spend on the off-chance that it may work!

Title: The S2 and hesitancy under boost
Message: Jon, One of the guys I met in the club last weekend was telling me about the exact same problem that he had with his S2, he told me that once he changed exhausts it sorted the problem out totally, I'm not sure what plug set up he was running but he seemed to think that the problem was due to flow restriction of the exhaust rather than a lack of fuel or a spark problem, in fact on his recommendation I have ordered the same system as what he had and am very much looking forward to getting it. Perhaps this could be your problem too?


Mar 14, 2003 - 05:28 - From: Jon B
Title: Sparkplugs
Message: Thanks for that Sean. I hadn't thought about the exhaust. The exhaust is a notorious bottleneck, particularly in the S2. The hesitation is not all the way up the rev range which you would expect if it was the exhaust. Over 5000 rpm it seems to clear and runs fine. Very confusing!

I have had them in the wet (150 miles of highway), and though I never pushed them, they never seemed to be having grip issues. If you want something with a bit longer life, the Falken Azenis has received lots of kudos as well.

Title: Jon B : hesitancy under boost
Message: Jon, I get exactly the same thing in my s1. My boost gauge reaches about .75 on the gauge and I get a hesitation. Its more noticeable on the motorway, accelerating from 80/90 onwards. Acceleration in low gears is fine, especially as you tend to change up. I've tried reducing the boost level and playing with the ignition timing which appears to help a bit. I was thinking it was to do with not running a rich fuel mix. Let me know if the exhaust fixes the problem.

Message: James, It appears that this is more common than I first thought - which in a way is quite reassuring for me!! Mine is the same as yours. OK through the gears but at higher speeds in 4th or 5th it is quite noticeable. At the moment I don't feel confident about fiddling about with the timing but I have an adaptor on order so I can link my laptop to the ecu via ElanScan. Hopefully the readings from this will shed some light. Jon

Title: Windstop
Message: Gary, if it was Pacific Blue that was probably Rod's car you need to look at Rod's site www.mardibloke.co.uk  It's the Oris Windstop for the MX5. I got mine from www.moss-shop.co.uk  it works well with the windows up you only get a small amount of draft, but it means you can wear a base ball cap without fear of it blowing away at speed! My tip's; you can actually mount the fixings with self tapping screws if you make suitable small holes with a drill first (and drill new corresponding smaller holes in the mounting fixings). You must put the mountings at exactly the same height as Rod did just above the carpet then the screws will go through the fibre glass wall and into the edge of the (metal)B post cross brace. I used longer bolts than rod so mine are mounted at the ends of the straight length of plastic trim. I also cut down and re-drilled the mounting flange on the prongs that attach to the Windstop and the plastic mounting flanges on the Windstop so as not to limit the rear seat back travel too much (the need for this depends how far back you like to lean the seat back for driving).

Title: MBC Possible Boost Spikes/Creep
Message: Hello everybody, Have owned my Elan SE for 6 Years now and have been a regular reader of this site. But have never posted anything. My Elan until recently was standard factory form, but have now installed a 2.5" Bore Stainless steel straight through exhaust and just built the MBC as described on this site. My problem is after changing into second gear and accelerating flat out the boost gauge seems at first to register 0.75 bar hesitates jumps to 0.8 bar hesitates then hits the cut off limit. Seems all right though accelerating hard in first gear (just goes upto 0.75 bar). I read on this site that the hosing to the MBC must be kept as short as possible. This I have done one side of the valve about 3 inches (to the turbo) the other side of the valve about 10" (to the wastegate). Should these lengths be equal or does it not matter. Also I assume I've disconnected the BSV by just pulling out the electric plug is this so or do I have to do something else. Hope someone can help as I love the extra power.

Title: Buckled Wheel
Message: Ryan, Great news you found the vacuum pipe problem. Your wheels are the standard 15" OZ ones fitted to the car when new. The do buckle quite easily as they are rather light ( hence keeping unsprung weight down and making the car handle so well ). You can try and find a wheel, but to be honest most 10 year + 15" wheels will need checking out anyway. You could go for a set of USA 16" wheels ( Federal ) as these are pretty light too, but you would need a set of four plus new tyres. Or you could pop a set of 16" S2 alloys on, which look much more modern, again you would need a set of four plus tyres. These wheels are stronger but hence heavier, and recommendation is to change to S2 suspension set up = £££ http://www.thelotuscentre.com/ can help you out with all three options, as they trade in old 15" for federal and S2 wheels. Oh, guess you could just get non-Lotus afterfit wheels, but note that the Elan has a larger than normal offset, so if you want to maintain the ride and handling you need to choose with care. My approach was to just get my wheels mended and refurbished. I was very pleased with the results, and I recommend this place, just as a happy customer ( think it was £200 to get four wheels done and they look like new, and no buckles ). http://www.alloywheelrepair.co.uk/contactlocateus.htm Hope that helps.

Message: Thanks for replying Rod. MBC was made using brass branch T, air vent screwed into top of branch and pipe nipples screwed into branch to receive new 1/4 inch hose. All connections to valve, turbo & wastegate jubilee clipped tight. It looks very similar to Scott's MBC example shown on this site. I think though the valve might be leaking a bit of pressure (still goes over 0.4Bar with the valve closed) Going to put some PFTE tape over the threads to seal them can only think this is where it's leaking!! If this doesn't work going to buy your valve and install as you have shown. The location up by the BSV seems a better place than right by the turbo anyway. Thanks again for your help.

Title: Hesitation
Message: Hi guys. I lately read about this hesitation under overboost after changing to 2.5" exhaust. Some say that this is due to cables' failure. Well, I kinda disagree. I think that when we alter the exhaust from 2" to 2.5", we let the gases flow more than before, thus allowing the turbo spin more. So the boost increases. This is the point where the electronic cut occurs. It seems quite logical to me. I also changed to a 2.5" downpipe a couple of days ago (I changed the catalytic converter 10 days ago) and experienced the same problem, but when I reduced the boost everything went back to normal except the torque that seems to grown up quite a lot. Anyway, I'll visit the service garage to let the mechs set the overboost to 0.9, with the Tech-1. :)

Title: S2 Wheel bolts
Message: THe S2 BBS bolts seem to have exactly the same size thread, base flange and bevel but the bolt head is a reduced size across the flats. If you fitted SE wheel nuts into S2 wheels there would probably not be enough room for the standard SE wheel brace to fit over the bolts. It's possible a socket might just fit but I've never tried this and don't have any SE wheel bolts anymore to test it out. Laurence

Title: boost creep
Message: Ian, sounds like your car is overboosting due to boost creep. It has been an issue for a number of folks here who have replaced exhausts, and I am not totally sure what they did to fix it. I had some creep after installing the MBC on a stock exhaust in 3rd/4th gear roll-ons of power which was only solved by decreasing boost through the MBC a touch. Another option is to fashion a fuel cut adjuster (or see below) that raises the limit of boost it takes to trip the overboost protection. I wouldn't do this however without a) a different boost gauge, b) an air/fuel meter, and/or c) an EGT gauge. Too many things can go wrong unless you monitor what's happening and correct problems. As for hose length to/from the MBC: a few inches one way or another should make absolutely no difference. I don't think you have any leaks, either. 0.4 bar is ~ the stock sensitivity for the wastegate actuator. It sounds as if it is working properly. One last: Dimitris. How exactly is the garage going to set your overboost with a Tech 1? The Tech 1 is read-only. The main ways to modify your overboost protection is to trick the MAP sensor into thinking it is seeing less boost (bleed valve), change the signal heading to the ECU from the MAP (FCA/FCE - as mentioned above), or (like I did) use a 3-bar MAP sensor. Just trying to save you a trip to the garage!

It will only raise the front a few inches but could possibly be useful sometimes if you don't want to bother with a trolly jack and axle stands. Laurence

These seem like such tiny weights, but do they actually make a reasonable difference to the handling - I assume that is what they are there for.

Message: Have fiited a baileymotorsports dump valve and its has a very visible effect of improving acceleration when I am flooring it. Especially between 2-3-4 gears. However I have a few questions. The boost gauge now seems to be at 0.2 bar as a start point (even in idle) is this right? Also should the dump valve sound even when I am easing off the gas when cruising in 3 & 4th gears at levels where i don't think the turbo is active? Now accelration seems slower above 90mph (this could just be relative)is this normal? The dump valve is the only modification on my car, but the front pipe on the exhaust(after the down pipe) is blowing badly (supplier waiting on part). Any ideas? Cheers

Title: Warren
Message: Warren, there is no way to have +0.2Bar pressure at idle so thus your gauge is off. Since it just did it and since the problem is the same 99% of the time, you need to check to see the black wire going to the boost transducer is loose at the screw at the base of the bracket and then re-tighten it which should fix the problem. There's really no other explanation, which is good.

You have the same symptoms (vis-a-vis dump valve) as I have with a Bailey...I think the spring's not strong enough, I'm sure it shouldn't be almost constantly venting while cruising and venting after only the most gentle accelration. The noise is awful too. I've bought an adjustable recirculator from FSE (FHE?) and it'll get fitted the minute this Iraqi conflict calms down. My Bailey will appear on eBay shortly afterwards.

Title: Dump valves
Message: Warren, I had the same issue with the HKS valve in 4th and 5th. If the valve is set too sensitive, under slight vacuum (such as lifting slightly at highway speeds) it will open. If the intake system is charged with boost, this is fine as air goes out the valve. If there is no boost, this can be bad as unfiltered air will actually suck in through the valve. Unless you are driving in real dusty conditions, it's probably not a major issue, but it may make some think twice about adding a recirculation-type kit (like Simon mentioned) or fashioning your own.

Message: Well, I got my big 'care package' from SJS last week, full of new dampers and other assorted bits. Just wanted to report how much I like these new dampers/struts! They are each adjustable for ride height and damping rate. Let's just say my old struts were shot--about 80K miles and they bounce all over the place--reminds me of a bouncy Cadillac ride. I put one in (the left rear) a few days ago, and then drove the car a few times. Boy does it make an obvious difference! The left rear felt as if it were hugging along the road nice and firm, while I could feel the other 3 corners of the car bouncing all around! Inspired, I put the right rear in today; drove the car, and yet again, I can feel that the entire rear is riding beautifully while the front still is bouncing around. Am so happy and inspired now that I am planning a late night install of the right front tonite. Definitely worth the money; and I'd bet almost all of us have tired original struts now . . .

Title: Dump Valve - FSE (FHE)?
Message: Dave/Darren

Fitted the new valve this morning and took Stripey out for a quick lunchtime fling around Middlesex (night shift does have its benefits!)...This is a vast improvement on the Bailey BOV (IMHO) even at stock adjustment (I haven't plumbed the recirculating hose yet, as I want to get the dump setting right first and I can't see how you can know when it's dumping if you're recirculating, because of the supposed lack of noise. Be warned though, the diameter of the inlet flange is substantially smaller than that of the Bailey. I managed, however, to compress the Bailey hose (part of the BOV-associated fitting kit) sufficiently (without leaks) to get a good fit to the T piece. The new unit dumps later and doesn't appear to be constantly wanting to vent ad nauseam! Furthermore, if anyone wants to use one of these as a normal (non-recirculating) BOV, it has a classier "Whooooooosh!" than the Bailey...more of a "bl**dy great sneeze" than a "Puuufff". Any offers of a more onomatopoeic description of a functioning BOV, much appreciated.

You've caught me on the hop though; what little paperwork I had when I ordered it [the BOV]is at home in Worcestershire and the box is up in my room in the Mess...and I'm down in a bunker 3 storeys underground.

Can I get back to you at a later date please guys?

Title: Rough crawling
Message: Richard, what you describe doesn't sound all that abnormal to me. In most cases you do want your sports car to take off aggressively when you open the throttle ;-) At a guess, maybe you could adjust the throttle position sensor so that the ECU detected "off idle" conditions at a slightly lower throttle position to smooth the transition slightly. The ECU detects you accelerating from idle by looking for a certain %age signal from the sensor, which may equal a smaller or larger movement of the throttle, depending on adjustment. You'd need a tech-1 of Elanscan to set it properly.

Message: My Bosch recirculating dump valve (off a Saab 900) makes a barely audible "phssshhhhhh" when it opens.

FWIW it opens whenever the inlet manifold goes under vacuum.

Title: BOV & Rough Crawling
Message: After much perusal of this site re BOVs, I installed a Tial BOV. I chose the Tial instead of the HKS cos the supplier here (in Oz) did not have the hoses to go with the HKS (other wise I would have installed the HKS). The Tial is more expensive, and does not allow any adjustment. It is capable of holding up to 3.0 bar (if that's the right term - holding). According to the supplier, this BOV works on a piston/diaphram steup instead of springs. I have now had the Tial for over a year with zero problems. In hindsight, I'm glad of this decision (thanks to HKS supplier!!) as I don't want to keep adjusting springs, etc. You can also get a recirculating BOV from Tial, but it costs more & I didn't want to cut a hole in the air box. The Tial does not come with hoses or 'T' piece. I had a 'T' piece fashioned out of steel pipe & installed it with the existing hose. I do on occasion get rough crawling, usually when the car is cold. I either just throw it back into neutral, select 1st & go again, or gently increase revs whilst it's hopping around (no stranger to kangaroos here!!). This seems to work for me. As I said, I don't get it often enough to worry about. Regards......Mars

First of all I can surely change the gear in 1/4 second and likely do most of them in under 1/2 second, but I don't see how that matters.

I put the front damper spring baseplate to yolk bolt distance 2cm shorter than the stock damper. I decided to put the adjuster dial facing inboard, rather than outboard [outboard=as I had done on the rears] as I figured I could reach this with the car on the ground and wheels turned to the lock so I could adjust it easily.

Title: dump valve
Message: Doug, what I mean is that, I reckon the audible sound is more than just the pressure in the manifold being dumped - it's the sound of the compressor still trying to pump air as it slows down. Thus what I'm saying is that if you want to see a performance benefit from your dump valve, you've got to get back on full throttle before that compressor wheel slows down completely! One of my Elanscan files has some brisk gear changes - from 100% throttle to 100% throttle in ~0.6 seconds. This is changing up at 6000+ rpm, so not exactly gentle driving ;-) I'm judging the dump valve performance here by how much boost there is at the instant the throttle gets back to 100% open. Going from 1st to 2nd, the boost came back in at 0.11 bar. Going from 2nd to 3rd, the boost came back in at 0.27 bar, but the gear change looks very slightly quicker. So as I say, you've really got to be quick on the shift to get any extra boost.......Rob.

Since filling up (to the brim) the other day on premium unleaded (95 ron) at shell I have been driving as economically as possible.

Title: Sport exhaust from Paul Matty
Message: Gregor

I can personally recommend the PM sports exhaust. I've had mine for about 3 weeks now and it's great. Nice tone without being boy-racerish and heaps more performance.

On the downside however is that they are prone to causing overboost (Rob B built a device, designed by another owner whose name escapes me, to cure my overboost and it works a treat). The other option is the BBR chip/kit which costs about £400 IIRC.

Paul Matty is reluctant to sell the exhaust "as is" (£299+VAT) and prefers to fit them on his premises (£399+VAT all in). There is no problem with either SE or S2 cars being catered for. SE is easiest but he has ordered mid sections to accommodate the S2 brigade with cat or without cat. I got this from the horses mouth about 2 weeks ago. Hope this helps.

Message: Keith, if you are going to get a new/reconditioned turbo, it may be advisable to get some small mods done at the same time if you are that way inclined - you may find it will cost no extra. They are UK based again, but Turbo Dynamics will swap you a reconditioned turbo with any mods you want for a fixed price. Stronger wastegates and/or slightly bigger compressor and/or turbine blades could transform the car.

Title: The M100 Video
Message: I can take little credit other than bringing other peoples efforts together. It involves a PC under the drivers seat, running Elan Scan connected to ECU to log data, and two web cams connected logging video footage. Park the car in the garage and the wireless card in the PC allows me to connect and trasnfer the ( huge ) files. A chum ( Matt D )has writted a program to take ECU data and create a "blue screen" video with the guages in the corner. Then a splice the front and rear cam footage together and overlay the blue screen video with the guages on. Finally picking a sound track, as all I am getting is wind noise right now. Lots more work for Matt to do on the ECU > Video program, but am pleased with first results, and we may eventually get the on track video Doug has always wanted :) Thanks for suggestions, what do people think to the quality ? I don't really want to go any higher quality as the files get huge ( that was about 10MB/minute of footage ),

I am having it coated at Jet-Hot, to stop that dreaded rust before it starts and also for the shear beauty. At that point I will take pictures. You will be shocked at the visual difference between 2 & 2 1/2", looking down through the neck of the PCE. Will either go up in the attic or to the highest bidder.

Message: Keith, I am doing my part to ask how you have deided it is the turbo leaking the oil?? Have you checked the cylinders, rings, plugs, seals, gaskets, or other sources of oil? Just want to be sure you don't replace it unless needed. There should be plenty of places around who could do a fine job of turbo rebuild, which should be the cheapest. You could send it wherever overseas if the price and result are worth it. You could make it better during rebuild by replacing with better components too.

Title: After the 2.5"
Message: Hello guys. As I already mentioned before, I changed the exhaust system to a 2.5" downpipe and a racing catalytic convertor. From this point further there is the 2" pipe and a high flow 2" final muffler. So, where is the problem? In the beginning there was this overboost >1 bar that I overcame with the BOV setting to lower rates. But there's another annoying and most probably harmful thing. There are many pops and sometimes bangs when changing gears (!!!) Does this mean that I'm running lean? How can this be fixed? Thank you. :)


Mar 26, 2003 - 02:10 - From: Matthew Welsh
Title: Pops & bangs

Title: Pops and bangs
Message: If anything pops and bangs indicate your running rich - its unburnt fuel igniting in the exhaust. Although I think its probably just that your exhaust is more free flowing than before so you hear it better, rather than any problem with the mixture - I certainly heard more pops and bangs after fitting a stainless exhaust with a straight through back box (only 2" though :( ). I had the mixture checked and it was ok...


Mar 26, 2003 - 03:28 - From: Doug
Title: pops
Message: Dimitris, I believe you are referring to popping/gurgling as with overrun/deceleration. This is likely due to the design of your exhaust with a greater diameter up front and only the 2" pipe after the cat. This allows a pressure change and disturbs the exhaust smooth flow in the system. This may be remedied with change to a total 2.5" system. On another note, my downpipe broke once and I drove the car this way for a few weeks. It has an incredibly nice sound raw out of the engine which is fiercely loud (set off all car alarms within a good raduis), and it was very gurgly and poppy in this form. The point being that the raw exhaust note does have some of this sound to it, so it also may just be the open nature of the system you have installed allowing you to better hear what is going on.

Title: Pops & Bangs
Message: Hi all. Thanks Matt, Alan, Doug. I think that it is most probably the restriction of the exhaust system after the cat (which is not a real problem) but I'm also afraid of a wrong mixture...

Mar 27, 2003 - 02:12 - From: Marie
Title: pops & bangs
Message: Hi All, I have the same problem when I wind the engine out. After much dyno time it was concluded that the almost backfire like sounds were caused by colder outside air rushing into the now 2.75" exhaust after hard acceleration then suddenly letting off the throttle. When the hot gasses of the exhaust meet the cold gasses rushing in it makes a gurgling/ popping sound. It's kinda cool sounding but its also an indicator of a rich mixture (i.e. the rich mixture of a turbocharged engine) The reason the stock exhaust doesn't do this is because the exhaust created by the engine still fills the narrow stock pipe enough to reduce/ eliminate this sound. When you go larger with the piping you would need to fill alot more area with exhast gasses to reduce the pooping sound (not going to happen so enjoy the sound) I ended up changing out my 2.5" exhausts after my high flow cat. took a poop and one of the monolithic "bricks" lodged itself into my 2.5" exhaust causing limited boost (.125 bar) and an overheated turbo. The 2.75" plumbing flows much better along with a custom built glass-pak muffler. All that I can say is wow it sounds mean. Happy elaning.

Title: BBR Interceptor 2000
Message: Darren, yes I did have a quick perusal but there are a lot of these devices out there now and the trick is being able to find someone who can (a) fit it to your car and (b) map it correctly - unless it's properly mapped it's effectively a worthless device. Most of these piggyback ECU's are designed to work off timing signals from standard Ford, Vauxhall or Rover cranks, some can be made to work with engines without a crank signal (like the Elan) but as such engines are pretty thin on the ground compared with the vast numbers of mainstream engines, it can get very fiddly and expensive. The Unichip is known to be able to work with a signal from the CAS in the Elan, the waveforms just need to be understood. Finally there is the mapping issue - the Unichip is designed to be fully mapped on a rolling road for every installation. Although alternatives like the Emerald can be mapped this way, it is more usual to provide a map from an existing "similar" engine installation - it's quite common for owners of upgraded Elises to swap maps with each other to try and find a best fit for their car, whereas a properly installed Unichip should be unique and perfect for that one vehicle. I don't know much about the BBR I2000, but their "kit" for the Elan has left a slightly sour taste in my mouth, and as I have some very local tuners that I know and like who can fit the Unichip, I think I'll be sticking with that.

Message: UGH! After all of the upgrading and replacing of worn parts, now my Elan is not starting. Towed it to the garage, and it starts fine for them. The story: I drove it about 1 mile. Stopped the engine for about 1 hour. Drove another mile or so. Stopped the engine for 5 minutes. Started the engine to go somewhere else. It started, but immediately stalled out, and would not restart, even after 1 hour. Flatbedded it to the mechanic (Harry Appleby) and it then started fine for him. Has anyone else experienced this? I don't like the idea of having this happen many times before it can be diagnosed. thanks in advance, Rich


Mar 28, 2003 - 12:00 - From: Doug
Title: won't start
Message: Rich, sounds like the old classic vapor lock in any other older car, but I doubt that is what is happening. That is because the Elan has a fuel return line to prevent just this. Does sound suspicious for perhaps weak fuel pressure = check fuel pump is coming on with key turn to run, perhaps clogging in fuel filter, or weak pump? Have Harry throw the Tech-1 on there to be sure the sensors are running right, as I can vouch if your coolant temp sensor (CTS) goes south it could cause something like this.

The performance difference is greater than when I had the 2.5" exhaust added. Harry says he "flogged it", but I think it may have just needed a good idle since the last battery disconnect. I'm hoping for the best. I looked at the fuel pump relay and its very clean and dry, no bad contacts there.

Worth asking him what he may have done with the Tech-1 though! Since no one mentioned it yet, thought I'd point out could be a faulty grounding somewhere. I remember the good old days when the car wouldn't start when the distributer got damp, so dad had to dry it out with a hairdryer and then car'd run fine--moral = could be some coil/ignition thing?

Title: Clay, where is fan switch?
Message: Sorry Guys my mistake. Memory not what it was. Rudz you are correct. Checking the wiring diagram it is fans or pump but not together. I think it would work if the cooling fan relay supply was changed to permanent live and connection at terminal 87a moved to 87 (or just piggy back them). The pressure swith would then operate the pump as well as the fans. ref wiring diagram sheet 18. Not sure how easy this would be. Alternatively you could also use another relay wired same as the cooling fan relay but with a permanent live supply to terminal 86. Don't forget to use fuses as appropriate!

Title: Philip, gear knob
Message: Philip, I fitted my car with the carbon-fibre Momo Combat know a couple of years ago. Great fit, feels even better. Really easy to install and no fitting problems at all.

Title: Headlight conversion
Message: I'm trying to get some input regarding upgrading my headlights to HID. I know there were a couple of people that did this, what are your thoughts? Was the installation a pain in the ass or was it pretty simple? Also, I admit I'm not a good mechanic, especially an electrician..., so I'm a little nervous about doing the ballasts...etc... Any input will be appreciated. Since I got a burnt out bulb as well as a worn out motor (got the rebuilt kits for both sides), I thought it would be smart to do the conversion at the same time. By the way, here is a site I've found. http://www.headlights-hid.com/HID_HEADLIGHTS.htm If anyone knows I can get the kit at a lower price, please inform me. :-) Thanks, George

Title: battery
Message: Ryan, you did not say how old the current battery is, but my guess is that it is completely shot. I've had this happen a number of times with other cars--a reluctant start and then nothing, even after the battery should have been charged by driving. It seems to be the symptom of an internal short in the battery--it can no longer take a charge nor can it deliver the required "juice". Time for a new one! Joel

Title: rear calipers
Message: John, interesting timing about your problem, as I have my rear calipers off the car and am in process of rebuilding one of them. The rear brakes get little braking activity as the proportioning valves shunt 85% of the brakeline pressure to the front brakes. I wonder what your mechanic is referring to when he says they are worn out. I am replacing 1 seal, 1 rubber boot and a 2 way check valve, with total cost less than $50 plus my labor. Harry down at Viking Motors in LA offered to sell me a pair of calipers at $300 each, so the new ones aren't cheap. Ask your mechanic if the calipers can be rebuilt rather than replaced.

Title: battery/gear knob/HID
Message: Ryan, you may want to unplug your trunk light. The switch seems to be the culprit in most cases, leaving the light on. The battery may just be a goner, however. A battery shop can test it to see how the cells are. Philip, I have fitted a Momo knob and just left the gaitor loose. You can barely see at http://www.lotuselancentral.com/images/swheel/newwheel.jpg It looks fine IMO. George, careful on HID conversions. If it is just the bulb that is replaced, the orientation of the Xenon arc with respect to the stock filament within the reflector may be different. What happens then is the angles of reflection change and your beam pattern may be horrible. This happened to some extent when I replaced higher output bulbs (not even HID) into my Subaru. If you do, replace the entire reflector assembly, otherwise you may be very disappointed.

Title: B+C service
Message: Hi, Does anyone know of a good and inexpensive place to get a B+C (cambelt change) service. My car has 84000 miles on the clock and I am quite sure its still on the original cambelt. This plus the usual need changing and checking over.The guy I usually use has quoted me a rough price of £600-£700. This seems a bit rich (SJ Sportscars quote £425+ Vat)but that's in Devon and I live in Windsor, Berks. Thanks for previous advice on dump valve etc.

Title: Rear Calipers M100
Message: John, the handbrake lever can seize in place causing the pads to contact the discs, sliding pin problems and that's about it. Your options are, buy a seal & pin kit from SJ and do it yourself (beware there's a special tool required (?)) or get them re-con'd by either SJ Sportscars or Classic brakes, both of which are circa £120-130 per caliper. Failing that, buy them new from either Lotus (£200+ each) or off the internet, they're off a 1989 Pontiac Grand Prix (rears & pick the heavy duty version). For info, I'm having my internet Pontiac calipers fitted on 8th April, I'll report back my findings etc. Darren.

Title: Dave, HID Conversion
Message: Dave, I think the HID conversion kit requires you to replace the whole housing, which include the reflectors. With the H5006 type sealed beam the factory use on the Elan, it seems that every time you got a burnt out bulb, you have to replace the whole housing assembly. Did you do a conversion so you do not have to replace the whole housing but just the bulb? You mentioned you got higher wattage bulbs for the Elan, was there a noticeable difference? If that's the case, it may a route I'll go with instead, since it's a lot cheaper... By the way, do you have to modify the wirings so the new bulbs get the electrical current it requires? Thanks, George

Title: rear caliper question
Message: Mark, as you have your rear calipers in bits at the mo' would you be good enough to tell me if I will be able to fix a non operational "ratchet" adjuster thingy? My mechanic has advised on an exchange unit but I would prefer to fix it if its possible.

Title: Rear Calipers
Message: There may be something I am missing here..but I was told by several people that know, that the rear calipers are form the W body GM cars from the late 80's. I would think that these are easy to find and cheap to replace. There was a huge class action lawsuit with these. GM had to provide the bushing kits to retrofit so they don't freeze up so easily. I have forgotten what the W cars were...but it was like the LaSabre or other mid range GM here in the States.

Title: Rear Calipers
Message: Tony, as mentioned above, I bought my rears from the US (long story) and can confirm they are from a Buick Regal 1990-1993/Chevy Lumina 1990-1994/Oldsmobile Cutlass Supreme 1989-93 or a Pontiac Grand Prix 1989-1993 (not sure if these are GM wide bodies, it's a UK thing). Your also right to say that the US versions are rebushed, to quote the sales ad "heavy duty option is fitted with problem solving hard anodised aluminium bushing and including lever, bracket and spring". Now, as also mentioned to Doug, I haven't had these fitted yet as there are a few subtle differences, namely the caliper mounting and one of the levers doesn't have provision to mount the handbrake cable but I'm hoping these items can be removed from my originals. I'll have more info after the 8th April. Darren.

Title: Calipers, calipers and more calipers
Message: Why I'm on the subject of calipers, the fronts are off a 1989 Pontiac LeMans GSE 2.0, make sure it is the GSE 2.0 and not the 1.6, as they're NOT the same. Hope this helps, Darren.

Message: Can anyone tell me why when I try to start my Elan all I get is a clattering noise from the starter motor which doesn’t engage the flywheel? Could it be a weak battery? TIA Graham
