600 plus to 900 plus rwhp feedback

Ok who went from 600 plus to 900 plus rwhp and can give feed back on reliability with a solid built motor, the difference in power/feel/thrill or lag difference? I got the pro efi set up which will handle the traction control and probably going to run the 6766 or new 6870 precision turbo. Also cheapest way to prevent wheel hop on the stage 2 pro efi launch. Thanks

Unless you plan to go wide body/custom rear quarters stick with 6-700 whp is my honest opinion

Not so much on the 1000 whp beast but with my lsb vert I have hook up with only stage 1 max psi because of the stock traction control sucks compared to pro efi, going to try stickier tires next year but it's my summer cruiser so nothing that will affect driving in the rain, I wish one day to do a AWD conversion like you did but I wish it was possible on coupe, Mert your far past a boss your a king, hope to see more of your videos soon! Would love to see a UGR
Lambo vs your car once it's all done, I'll cheer for you brother, S54 is the best!!

Thank you Tom.

Hoosier R6 is what gave good traction in rwd mode, 315-30-18 R6.

On a coupe M3, it is possible but is it possible w/o cutting chasis is the question. In january, I ll be putting my M3 Coupe on lift and see if awd is an option.

Yes, it does hook but at the expense of 220 lbs of extra weight.
Yes, it does launch nicely. It does not spin wheels. Feels solid.

1 point I still cannot figure out is my E36 Euro M3 TT (RWD) does hook as good as my AWD E46 M3 from 50 mph. I really really cannot figure out why.
I am sad as I cannot find out why E36 hooks better on 12 years old shocks.

AWD M3 vs Gallardo, hmmm. They are the real big boys with 5.2 L engines.
I ll push S54 XM3 further and see what it will do.

Once we see good time figures with XM3, plans are getting another 330xi or maybe a E92 Coupe and swap a 440 cid billet aluminium V8 with twin 88 mm turbos. Most probably next year this time. But first see what XM3 can do.

Just saw your sig, it tells a lot. 3.91 ring and pinion.

Remove this ratio.

Put 2,93:1 ring and pinion.

Boost build / load build will improve, traction will improve.

for the strip or for the street?

your final drive is too short, 391 is sky high for turbocharging.

anywhere between 2.9/3.07/3.15/3.23 would be much better for traction

Fitting an OS Giken super LOK or E39 M5 clutch type LSD would also help wonders for 60' if your unit is currently a stock M-variable.


Locally a friend is running a 1200rwhp e36m without much traction issues (strip only). its got a lower final drive and built clutch type diff, quite reliable.

I'm a little over 800whp and don't have a huge amount of troubles getting the power to the ground above 2nd gear on 295/19's R888. I'm going to switch to a 275/40/18 ad see how it works.

At 800rwhp(ish) and 295 R888's or so (on 18's) you shouldn't have horrible traction. When your traction control is dialed in properly its amazing how much faster the car gets. Spinning isn't winning, pull out power until it hooks then bump the traction control up a hair from there, you want just a little loss, be on the edge. We did that back when I was on proefi and cut 1.5 seconds from my 60-130 and that was on 265's on 19"s.. not sure what my 60-130 is now days as I always forgot my vbox at home when I went to shift s3ctor but if I had to guess its extremely low 5's. Kenton's would be right around there as well, if not better as he had a little more meat.

Thanks for info. Car will be used for street. I had the 3:91 gears in before the turbo but they seem to work well though. I pulled the trigger with undercover performance to go 900 rwhp staying with the pro efi. I never been in 900 plus car so hope it's one fun run with traction of course
