hmm, i see, was he running drag radials or the stock RFTs? because his 60 ft is pretty bad too, nearly 2.2

Shiv, compared to the PROcede cars tested in LA your coupe with exhaust seems to make MUCh better power at the very high end

Is this because of the exhaust?

This would also make a substantial difference in your 1/4 mile times, since you can shift almost at 7K and reap the benefits of a better power curve.

EDIT: Woops, this is the dyno with the PROcede and exhaust. Still, significantly more power than no exhaust PROcede cars. And the flattest power curve I have ever seen! http://www.e90post.com/forums/showthread.php?t=43252

Any word on when you might have the exhaust ready for production?

For those of you that are running stock street tires at the strip DO NOT roll through the water/bleach pit.

Youre not looking for smoke or some crowd pleasing spinning. Just a quick warmup. Also, put the tire pressure more around 25-28.

Definitely shift around 6300-6500. Theres no reason to take it to redline to ween any extra power out of it. Youre already out of the powerband. If youre doing it because you think youll be in a better powerband in the next gear, it wont matter. The torque comes on at 1400 and stays there. You could shift at 4500 rpm and still be in the meaty part of the powerband. It has nothing to do with trying to get the best boost psi. Shifting should only take .3 to .5(if youre getting the hang of it) each. You can try powershifting(leaving the foot on the throttle between shifts) but could burn out the clutch sooner.

Good luck!

Does anyone recall any instances of parts breakage with a good street traction setup (low tire pressure around 25-28psi & a mild burnout to heat the rubber it bit), i.e, tranny gears, half shafts, u-joints, etc?

Lurking here for several months since people have been racing good Procede setups with exhausts and good gas, I haven't seen anything on parts breaking. That must mean there are some fairly over-engineered drivetrain components in these cars from the factory...nice warm fuzzy feeling building...

[ksfrogman]

Wow Tyler, that's awesome!

[IMJUSS2NASTY]

Theres no way to keep the boost running all the way till 7 k rpm?

His best ET was a 13.678....best MPH 103.692
My best ET was a 14.068....best MPH 100.602.

And that was in the daytime, warmer temps, 2700ft. Down at sea level, cool air, my M3 will run low 13's @106-107MPH, slightly faster than my 335i steptronic does(13.268@105.36mph+ under the same conditions.) So I just figured that the higher elevation affects the turbocharged 335i less than the NA M3 engine. So either that 335i wasn't stock like he said...or I don't understand how the Procede 335i is slower than his car. And even with the Procede, it seems that the 335i is only running .3 sec quicker, and about 3mph quicker than my stock M3. At Famosa my M3 ran a little over 104mph, and the Procede 335i sedans were running in the 107mph range. One was running low 13's and one mid 13's just like my M3. Actually I had a quicker Et than the one 335i with the Manual/DRs. Does this make any sense? Well at the Famosa event, I figured I would have to gain about 35hp to keep up with the Procede 335i. But at LACR, I don't understand how the Procede 335i is not running as quick as the stock 335i I raced against? In fact the 102.4mph of the Procede is only 1.8mph faster than my 100.6mph run. And in that particular run my 60' time was not that great at 2.362 secs. 111mph is really nice...but so far we have seen 102.4-107.6mph range from most of the Procede equipped 335i vehicles.

I used to race my supercharged M3 competitively on DR's for a few seasons(plus auto-x's) and the only thing in that time I had to replace was my clutch and a flex-disc(aka Guibo Coupler). We are talking probably about 30+ 1/4mile runs a season. I think the parts can withstand a lot.

[PresaMat]

I hit the track last night... couldnt get any traction and my clutch was slipping bad... i got some low-mid 13s and 107+ ETs with the MT and stupid runflats. There was no way around the water pit either. I really need to get a new set of tires and a clutch.

I really feel that because of the superstiff sidewall of the runflats, theres not enough flex in them to transfer the torque to the ground without slipping. This is where even normal street tires will help when you can lower the pressure a good 10lbs.

i guess ill put a link in my sig to the thread of my car so u all can see what mods IVe done! Yes I compared STOCK to PROCEDE it was about .3 .4 of a sec difference in the 1/4/mile for me at that same day!!! Im pretty sure i even posted the stock results somewhere on the first page of this thread.
havent had much time to get back out there sooon sooon there will be more slips!!
and Honestly i heard about your famosa trip u guys got 3 maybe 4 runs i think, Whats up with that? thats wack id be pissed i got over 15 runs that same day at lacr and couldve done more but we left! Ya its almost 3k feet above sea level but u do the math it comes right into play at 13.2!!!

[Inkidoo]

Wow, ADHD, those are some horrible numbers for a Procede. I would practive some more, or get somebody know knows to help you out.

mind you the track he is racing at is the slowest track on the west coast...and that is not even a joke.

Is that your car on dragtimes that ran 13.47 stock?

[AlexEvo]

if these cars break parts at 3xxWHP power levels then BMW really UNDERengineered these parts. i wouldnt expect to see parts breaking on them until the mid 400s range and thats IF you're running some super sticky drag radials or even slicks. on runflats you're probably good to 5xxWHP since they dont grip all that well.

[bnj]

Tire needs to be round. What you might lose in a start you gain easily back due to less rolling resistance.

Ouch! - is this your first manual car?

Yes... Sadly, I wanned more! but, I will wait until PROcede to go again.

By the way, I didn't mean to insult anybody saying you should get some practice. I mean, nobody is born knowing. I bet ADHD himself can get better numbers without anybody's help if he practices. There is a person here who said he got 12.6!!! (wow). I accept 1/4 mile racing is a very borring sport , but once you get addicted, you can't quit!!! . Mabybe this track that is real bad, I have never been there, so I apologize to everybody.

You know, I find it strange. The other day, a couple of weeks ago, I raced a 335i Coupe on the Orlando Speed Way. He had the same car literaly. 335i, Sport Package, Steptronic, and even Blue (just not sedan). But he was running a 13.8 . He told me my car HAD to have something else. In fact, he asked me if I had the PROcede, or if I changed the gasoline to a higher octane. He ran agaisnt me and he was doing 13.8 while I did a 13.5 that run. My worst number has been 13.7 with a friend by my side. And my best was a 13.415 (I think, I will try to scan it with the University's scanner).

Again, I apologize. My intentions were good

That is a pretty good time and nice looking sedan in Montego

Times can vary a lot with different drivers, and nothing wrong with saying it takes practice, because its the truth! I am sure that guys coupe was capable of 13.4, but it could have been anything from his launch, to shifting too soon, shifting too late, maybe had DSC on, etc etc. There are simply so many variables when it comes to drag racing.

Looking forward to seeing your times with the PROcede

[ADHD]

wow some people just expect perfection right away!!
NO this is not my first manual car ive had plenty of hondas and even a 89 stang supped up..
This was the first time out at that track with this car mind u also the car only had 600 miles or so..This clutch in the 335 is completly differnt than any of my other clutches!! It sits really high compared to what im used to. I like to drag my heel and have some kind of pivot off my foot but its causing slippage and slower shift times! I honestly dont drove this car that much ever since my accident so over time yes i will practice and you all will see much better times!!
