Turbo M3 Track Day

Here ya go. This pull was in 4th gear, and the tune was intentionally left soft to keep the motor in one piece. Up top it had quite a bit of timing left to go but I didn't want it to make any more power and break

Sorry I didn't get around to posting pics today, I was having a really hard time with a very stubborn Mustang I was tuning today with a whipple, took most of my day. By the time I had a chance to take some pics one of our techs was already pulling stuff off the M to get the tranny off so its kinda in pieces right now. I'll post pics of the clutch when it comes apart and we see what the damage is.. I'm pretty sure I know what broke but we'll know for sure tomorrow.

Pulled the clutch out. The last disc welded itself to the floater. Looks like the diaphram fingers don't clear the part of the casing that supports the input shaft where the throw out bearing rides so the fingers were always depressed slightly causing the clutch to not be disengauged all the way. We're trying to work with the clutch company now to see if we can get this taken care of since it seems to be a design issue of the clutch itself from what we can tell.

Good Stuff Chris! Keep it up

Chris those numbers are pretty damn good for being on stock internals and to the wheels. The torque is also surprising to say the least. I am surprised this thread is not getting more attention.

Thanks, I think it may take more, but gonna have some fun with it first before we try to turn it up some more ..

Might be the title. I didn't even realize this thread was here until you posted the link from the proefi visit thread. If it would have said PRO EFI TURBO M3 HITS THE TRACK ! It probably would have gotten a bit more bites.

Anyway, GREAT RESULTS Bugermass !!!! Those are some crazy numbers !!! It's like hpf stage 2.75 with an assload more tq and without the motor build !

Feel free to change the title!! I don't think I can edit it at this point.

Eh, Unfortunately, i'm not he-man so I don't have the power. It's all good though. Hopefully more people will check this out as this is groundbreaking work by my understanding !

I'll defiantly keep things updated here. Like I said once we get everything back together and we run as fast as we can at this power level we'll probably turn it up a little at a time until she lets go. I'm very curious to see how much the stock rods and pistons can take.

How the hell ate you Malone 720 whp on stock internals at 20psi? I want this lol

You and me both man!

There is no way that the turbo is all in!! I just made 843 RWHP on a supra with a 6266 !! The 6766 will certainly make more!!


Great job Chris!!

Thanks Larrry, yeah I definatly agree theres more in the turbo. Just wanna keep it together for a while .. I have a feeling we may hit a wall with backpressure, as with this manifold I'm already at about 34psi of back pressure at 20 psi of boost. We plan an making a tubular mani later, but probably not until we pop this motor and put the built motor in.

I have a M3 now at the shop where the customer wants to hit 1K with a billet 76. I am now slightly afraid of the HPF log type manifold as being a restriction that will prevent us from hitting our goal. After seeing the results of Chris's car with a 82mm turbo, I think that we may need to explore the realms of a custom tubular manifold.

Oh it will certainly make more than 20 psi on a 3.2L motor. We routinely run 35+ psi on the supras and other motors that we use that turbo on.

Chris,
What are your thoughts on the internals longevity with this amount of whp and torque? Even if its close to 700whp, I would love to do the set up since its hitting the Stage 2.5 and Stage 3 whp territory and all w/out the build. Maybe adding the ARP head bolts to assist in holding it together? I am looking for all sorts of options/ideas to push the stock engine further.

Really good feedback there Larry, was this on E85 also?

Yes of course, and it made 844 Torque!!
