S1 Exige With Built K20a2 Rotrex Blower Etc.

[dstevens]

Not wanting to rain on your parade, but I see a crank pulley with no inertia ring - not a good idea.

[dstevens]

I made the wiring harness. Joe did the mounts, shifter, axles & exhaust.

Watching

Keep up the great work folks.

Love the car. Subscribed and learning tons. Thanks for sharing your build-up

good lord! must be an animal from 4K and up.

I'm just surprised at all the supercharged cars lack of torque down low. I thought SCs provided relatively flat torque curves. Must be because of the highly tuned cars I'm seeing.

Did you have the cams in the engine? These are the same cams which we found make less power than stock: dynocharts06_09civicsi

Compare to the Lotus supercharger - it's got more torque at 2000 rpm than the factory charger makes anywhere...

It is a centrifugal supercharger - basically a belt driven compressor out of a turbocharger. The output is a square of the speed. You're probably thinking about a positive displacement supercharger, which has a more linear output.

wow.cool vid.i miss seeing this series.speedvision used to show it back in the day.was that a k20 powered exige s1?they where calling it an elise.

[CUP_240]

And Lucas's Exige had approx 350hp flywheel as apposed to your beast ;-)

Unfortunetly Lucas's Exige was writen off in a big hit @ Philip Island ... Was a great car !

Also this was not a tight track that favors the elise. Sad that this car was totaled in a brutal accident soon after. Knew about this result but was unable to find the video until now.

What do you guys do? Looks like a serious bit of kit in the avatar.

so this was an elise s1 when new?so they swapped the bodywork for exige s1?what was the supercharger this car ran?yea its to bad this car was totaled.the car in my avatar is a west wx10 d sports racer.im the chassis fabricator and a crew chief at the races.the wx10 can run in both imsa lites and scca.it has proven to be faster than the top running formula atlantic cars in the country.last year at the run offs d sports was the fastest class in scca.there is some good race footage on the web site.West Race Cars - West Race Cars - Home Page

i really like what you have done with your car.i wish i could convert my 06 elise to k20 someday.i have held off modifying my 2zz because i would rather spend the money on the k20.

Cool footage of the gt3 in action and very cool to see a lotus do well against some of the best factory racers. A privateer with an engine out of a junkyard... amazing! Can hear the supercharger working overtime......

Very Very cool video.

How did the GT3 do against the Porsche's in the end?

i have not seen an exige/elise with a north/south engine placement.other than the z cars hyabusa bike engine elise.witch im not a fan off.i thought that if you did do a north/south engine you would need to modify the firewall.the west car is a very fast machine.i have only driven them in the pits.cant imagine how fast they would be.the vids dont do it justice.pull close to 4 gs in the corners.one of my ideas for the exige/elise would be a full tunnel floor.the only deal breaker for it would be the rear sub frame lower rail.the one that the under try bolts to.if that was not there.you could put some pretty big tunnels on one of these cars.i would build a complete floor from the shear panel all the way back.the center section of the floor would drop down to create the tunnel.start the ramp aft of the fuel tank.the alms gt2 porsh cars had a similar setup.

At Superlap in 08 Peter's car blitzed everthing, but what surprised me is that Mark Berrys R32 GTR that finished second is a animal of a car, extremly well setup racecar with over 700hp ... This particular car was sent over to Japan to compete @ Tsukuba Time Attack and placed very well against many factory workshop racecars.

Do you have the contact for the K20a conversion for S2 ?

Im very keen on this ....

Cheers

i have not seen these cars before.never searched for them.the red car looks like a sports racer.there are a few companies in the uk building this type of sports racer.the big plate that the trans bolts to.is mounted to the chassis struts coming off the rear bulkhead.if that could be done in a lotus.you could build some very effective tunnels.the a arms need to come all the way into and mount to the gearbox.like the red car has.if you look at the sub frame for the green s1.the a arms are still outboard like the stock lotus would be.also has cross bars down low that would block the tunnels.i think the v6 would fit better.being 1 cylinder shorter than a 4 cylinder engine.on the west car.the rear spar.the machined aluminum part that the rear arms mount to.is a replicated hewland from a formula ford.it has all the same a arm pick up points.there are no gears in it.just the chain driven diff.the bike motor has the gearbox in it.i will search for some of these cars you mentioned to see what they have done.

[kmt63]

what is the state of tune on this car?i see paddle shift.fender vents.must be a full on race car.sounds really good too.

[kmt63]

the use of the hewland and formula car style a arms would make room for some pretty good tunnels.if you have seen what an atlantic or champ car uses for tunnels.that is what i thought would be cool on a lotus.so at the rear bulkhead that is where the tunnel would start to ramp up.then your lower a arm would be in the tunnels(most formula cars use a streamline shaped tube).if you could pull this off.the car would have huge down force with low drag.this idea is a bit of a pipe dream but would be really cool if you could afford to do it.

Obviously a very fast Elise, but towards the end of the video it looks like the car in front is carrying a lot more corner speed. But, it doesn't make too much difference once he hits the straight.

Your car is THE $HIT! I have always wanted an S1. They are THE REAL cars. In fact my exhaust tips that come straight out the back were designed to be a tribute to THE original. Your car must be AMAZING to drive..
I originally bought my car from Mark Starr. Do you have any idea where is he now??
Wasn't Hunting Ridge was one of the first high end dealers to go out on the east coast?
Two shots of my car in its latest configuration..

I think your car is bad ass and the fact that it is an epitome of the Lotus philosophy is what does it for me. Can't wait to get out West... going to come by and see your car once in the neighborhood if that's Ok.

I thought HRM was out of business but their site is up and one of the listed contacts is Mark Starr? So, perhaps they are back. How did you join those carbon panels? Love it!!

The C/F panels are overlapped or butt joined and sealed with Sikaflex 1A. I believe it is the same adhesive/caulk that Lotus uses to attach the crash structure and body panels to the chassis(it seems to have the same properties anyway).
It's not quite 100% yet but it looks as if the car is going to a Lotustalker that lives in the mountains north of Santa Cruz, Ca. If you have never been there(Boulder Creek) it is an absolutley gorgeous place to live. A virtual paradise until we get a severe pacific winter storm in wich case you had better have a generator and a good store of food on hand. I would give my left one to live there though. Falling redwood trees are not an uncomon occurence there
Did you get your car directly from Mark or from the guy that bought it from him? I knew he had the car for track events when I got mine and lusted after it then. In California that car would be a headache to get on the road legally. I'm guessing that the car is fine for the street in Florida though.
