Here is a teaser about the changes we've made to the car.  Check it out at Car Domain (http://www.cardomain.com/ride/2980038)

It may be hard to recognize it as the same car.  Check out our car in Performance BMW Magazine too!

Good lord.  Your car is incredible.  way to go

it says 310mm brakes in the article.  Is that right, or are they the 300mm massive kit??
Title: Turbo M42 Race Car, Version 2.0
Post by: E30PQ on September 29, 2009, 05:59:44 PM
Thanks for the kind words.  

It has taken a lot of work to get this far and many long nights working on the car.  

We need to thank some of our sponsors like Eurostop USA (fiberglass body kit), Vorshlag Motorsports (engine mounts, trans mounts & camber plates), Metrix Motorsport (high performance diff) and Howerton Engineering (water injection) who helped us with version 2.0.

The brake kit is the Willwood kit that UUC sells.

That is just excellent work there.  You guys deserve the recognition of the article.  Is version 2 the same car but reworked?  Or is it a "new" car?

I want to buy a set of those rear fender flares you had on version one for my project.  They wouldn't be for sale would they?
Title: Turbo M42 Race Car, Version 2.0
Post by: E30PQ on September 30, 2009, 11:37:46 AM
Version 2 is the same car but completely reworked.  We basically took the car completely apart and rebuilt it making a bunch of changes.  Some of the work that we did:

- moved the engine back 1.5 inches
- moved the exhaust system back
- installed Getrag 240 (318is) trans
- re-routed the charge pipe from intercooler to TB
- new engine mounts, new trans mounts
- new camber plates, new M3 control arms, new CABs
- minor engine rebuild (new rings is all the engine needed)
- new water injection system
- new diff temp gauge
- installed newer E30 fuel tank
- new fuel tank filler under the wing
- reworked rear fender tire clearance
- new fibreglass body panels
- new graphics
- new rear wing & custom wing up rights
- designed/developed a new intake plenum
- removed spare tire well

The old fender flares are long gone.  You could purchase a new set of those flares from Eurostop USA.  Tell them we sent you.

Im intrigued by your choice to switch back to the m42 tranny. Is this purely a gearing choice? or trying to get the car lighter?

Will be interesting to see how well it holds up. The car has turned out great, a credit to the effort you guys put in. I'm very keen to tear into mine for stage 2!

This car started life as a 325i.  When we put the turbo M42 into the car we used the Getrag 260 (325i trans).  To do that we needed to move the engine forward about 1.5 inches.  We considered it a temporary solution until we could track down and install a Getrag 240 in the car.  It not only required a trans but it also required a drive shaft.

Our first goal was to put the M42 where BMW meant it to be which improves weight balance.  That should also provide a slight benefit to braking and handling.  

As a bonus, the Getrag 240 is lighter and many of the "version 2.0" mods were done to lighten the car.

Lastly we think the gearing difference should be good for us.  We need to run the car more in this new configuration to fully determine that.  

One of the main reasons we decided to build the M42 was because it is cheaper to build this motor over any BMW 6 cylinder.  2 less cylinders worth of parts makes it more cost effective.  Another reason is that since this isn't an "S" motor (a motor that came from an M3) parts are much cheaper.  Cores are plentiful and inexpensive vs. any M3 motor.  Availability and cost effectiveness also applies to Getrag 240's.

As with many systems on the car, we bring spares to each race.  We will have a spare trans in the trailer.  We could almost build another E30 with the spares we have in our trailer.

Thnks for the indepth reply :)
I'm gearing up to tear into my 318iS this off season and go boost, but on a much tighter budget than you guys ;)

I'm planning to move the engine back even further, using a 6 cylinder tailshaft (~100mm/4" shorter) and obviously custom engine mounts. You guys can think of yourselves as inspiration!

Your reason for choosing an M42 are much the same that I stuck with mine. Congrats on the very nice build, goodluck with the upcoming races. The car is a true credit to the DIY, hope to get mine there one day.

I noticed you tried running the whole grill covered up.  Did you run into an overheating issue?  I tried it in qualifying at Road Atlanta this O'fest and it ran a little hot in traffic and at low speeds. So, I kept just the headlights covered like what you have.

Your body work looks great especially where the fenders meet the side skirts.  Nice job.

I've toyed with the idea of going e-mod to try and set records.  Use a combo or a m50 b25 and a euro m50 b20 to get me right at the top of the displacement range.  Maybe an s52 head also.  Just ideas though.  The guys that run d-mod around are FAAAAST and I don't know if I'm ready to try and compete at there level just yet.  I still have the rookie X on the back so a little time under my belt isn't a bad idea before I move up.

We just decided to open it up to get the most air possible into the rad and oil cooler.  With ambient temps over 100 at many of the races last year we decided it made sense to let more air in.

We took the rookie X off the back of our car just about a year ago.

We decided to run in D-Mod because we wanted to run with more people.  Right now the car is faster than the driver.  I know my driving skills will improve with more seat time.

I remember when you guys were first building up this engine, what did you modify this engine with, stock rods, and lower comp pistons? I sold my car a few months ago and the guy who bought it cracked the oil pan blew the engine and left the car at my buddies shop who proceeded to get it back for me for free. I was thinking about rebuilding and turboing the engine and it seems like you guys are running the most reliable set up out there with very good results over many race weekends. Is there a link to the original build thread?

Thanks

I have a question. When you were putting in the drivers side cam chain rail, was it up against the back of the tiiming case or was it floating? Mine is floating about 1/4 inch away from the block. It looks ok but there are several threads showing between the rail and the case (not the front cover) from the upper threaded sleve and I'm trying to find out if that's normal or the cause of my at idle chain rattle. The rail doesn't seem to want to move and I tried turning the bolt without pulling the front cover but it's tight. If you can remember, I'd appreciate a reply about it.

That screw allows you to adjust how far that chain rail sits off the front of the head.  I doubt it's the cause of a chain rattle, but I suppose it could.  There should be a screw in it and if that's missing it would be your problem.

Those are DTM Fiberwerks fenders (EuroStop).  Call Ary he can set you up with that kit.  It's fiberglass and it is a little wider than the E30 M3.  The fronts are bolted on the rears are riveted and molded in.  We left the seam in the rear since its a race car but for a street car you could mold the entire fender in.  

Not sure if you saw Ary's car (the guy who runs DTM Fiberwerks and sells these kits).  His show car uses this kit and has it fully molded in.   It looks awesome.

We only have one test day with that transmission in the car besides driving it around the block and on and off the trailer a few times.

We went with the 240 to get the engine moved back in the engine bay where BMW put the engine when it came from the factory.  We moved it up a little with the 260 trans and drive shaft.  That was a temporary configuration that we ran for about a year.

We keep spares in the trailer if we run into problems.  We could almost build a whole E30 from the spares we take to the track.

We ran out at Buttonwillow last weekend.  The BMWCCA club race group ran with NASA GTS.  We had a good weekend.  Came in second in class on Saturday but unfortunately no video of that race.

We fought a few mechanical issues over the weekend and a few electrical issues.  One of the electrical issues stopped our Sunday race.  

Here is a video from Sunday's race.  Ran well for about 6 laps before we took the car off the track.  Didn't get a good start but raced a few cars hard.

Cool site and I can't wait to see what you guys have up for sale soon.  With the coil on plug kit does the stock cover still fit?  The photos on cardomain show you guys using a heat reflective panel.

No, the stock plastic cover doesn't fit over the COP kit.

We expect to add some used parts probably the last week of May due to other commitments time wise.  

More racing info should be added by the end of the week.

Cools vids, sounds the car runs great!
Were you having some problems with 2nd gear? There was one corner during the practice runs (tractor/bulldozer in view) where it seemed like you were taking extra care and time in your shifts.

I think the turn you are mentioning is called "Off Ramp" at Buttonwillow.  For those of you who aren't familiar with Buttonwillow sometimes they run the track counter clockwise which is why they name every turn instead of numbering them.

That noise is driver error.  Some times I rush the down shift into Off Ramp by forcing it into 2nd.   If I wait an extra second it slips into gear without any noise.

So we had the car on the dyno again last weekend.  Established a new base tune and then tuned for our water injection.  Add timing and picked up 24 RWHP to just shy of 300.

This is a good comparison of then and now.

This video was the first time we put the new turbo version of the car (2 yrs before v2.0) on the race track for testing.  That side exhaust was brutally loud.  No muffler just a cut out on the right side under the passenger door.

http://www.youtube.com/watch?v=KdXD64OORPA&NR=1 (http://www.youtube.com/watch?v=KdXD64OORPA&NR=1)

We were overboosting back then (we didn't know it at the time).  We were probably making about 340hp at the wheels (conservatively).  Once we figured out that problem we tuned the car up to 333 hp at the wheels at about 18lbs of boost.  It turned out to be a little bit too much for throttle modulation.  We have since tuned the car down to 295hp.

We decided to add some brake cooling to the car.

Here are some photos of the our brake ducts installed in the headlight frame.

Before paint and stainless steel screening.

Here are some photos of the final install of the brake ducts.  The headlight brake duct install is a compromise.  We would have liked a direct shot from the lower spot on the front bumper.  The challenge for us is that we need to be able to pull our front bumper to be able to load the car on the trailer.  It would be too much work to also have to hookup the brake ducts every time we needed to either pull or install the front bumper cover.

The left front on jack stands and with the steering wheel turned full left.
(http://i266.photobucket.com/albums/ii260/pquattro/IMG_0244.jpg)

This is looking up toward where the duct comes from the headlight.
(http://i266.photobucket.com/albums/ii260/pquattro/IMG_0239.jpg)

This is a photo of the right side brake duct showing its path down toward the wheel.

Someone asked about the flex joints we added to our exhaust.  We added 2 flex joints in total.  One is visible in this photo.  The other is on the down pipe after the waste gate.

Yes, those numbers are to the rear wheels.

We have the wastegate set at 16 lbs (we havent't changed it from the last time we were on the dyno).  It's making about 18 lbs.

So many of you know that we run a turbo M42 in BMW Club Racing. We've had a lot of fun, but decided that over the course of this season we're going to take the car in a different direction.

In order to fund this, we're going to be selling some of our M42 specific spare parts. We have a few heads (at least one of which is fresh from the machine shop and never run), at least 1 block with custom rods, an aluminum fly wheel, intake manifolds, etc.

If there is interest in the 17X9 wheels (4 lug) we may make a set of those available as we move back to a square setup.

Check the For Sale section for details.
