Damn guys,

I am very impressed by the progress you guys are making. Here I was thinking my car was quick running 11psi.

All that means is back to modding again for me.

Dude with you running that much boost, what are you thinking posting without a video clip....

uh oh I read on PT... whats the news buddy? Any ideas on what needs fixin?

Prolly just needs some tuning... We can only hope I guess.

Yeah post up those compression numbers. I am curious.

If all else fails, go with a stock DE. I have been pushing 18 psi for awhile now and all is well. 20k boosted miles now!

What happened? i wanna know, i hope you didnt blow shiet up. You should of been able to tune no problem with an egt gauge and a wideband....and even then you should still run it a little on the rich side to be safe. Keep us posted on what goes down though. Peace

Sounds like Fun and I know you are itchin to go fast... but stop being a damn idiot and go have your car tuned before you blow it up.

When I first looked at that is looked like Gay smiles.... Now I get it.

Anyways, All it takes is one detonation at 20 PSI and your motor is toast. But it sure sounds like blow-by from how you described it on probetalk cause that should really be the only way smoke comes out of your valvecover.

ahhhhhh man, that sucks soo bad. Makes me wanna go hit up a dyno asap. Sounds like you may have had your timing too advanced, so when boost came on.....boom. 20psi is alot of boost for being untuned, i'd only run 12psi semi tuned on my bp which is pretty stout, couldnt imagine running 20, too many variables to consider. Keep us posted. []Deace

Since my wideband broke, I tuned for 18 psi purely by ear.

There is a difference between being and idiot and not knowing what you're doing.

I wouldnt consider myself and idiot simply because I didnt go to the dyno to tune. It has worked out great for me thus far.

lol I didn't see this topic was going in (no email notification) anyways. ya 6 rings are dead. I was runnin fine on 20psi (14-15 degres timing) but I dropped down the boost a little for daily driving. that's when things went bad. For those who has MS will understand. I dropped down the boost WITHOUT changing the timing maps. That means I was running the numbers lower in the map (wasn't tune for it) so I was running like 24-25 degree instead of 14-15 (way too much) and I didn't notice it. result predetonation and 6 bad rings.

I'm taking the heads off soon, if the rings are the only problem, then I'm fixin and going ahead with my project (turbo cams, solid hla's head studs, tranny build etc...)
if the pistons are toast, there's no way I'm buying another set of pistons at the price they cost and I'm putting my car up for sale (well part out that is)

I surely hope though the the rings are the only problem.

and GRO yeah I was about to make some vids THE day things went the worst.
the only thing I got (no dyno, no slips, no vid.) is a 80-120 time
In 4th gear without downshifting, my 80-120 (kph) is around 3.8 sec. (not even in my power range) on 16psi untuned. probably like 3sec if I could downshift.
anyways that's it for me this year folks. Next year will be better. I will have a chance to enjoy my car at least

bmwm3guy · Post by **bmwm3guy** » September 15th, 2005, 10:02 am

the pistons are brand new... I have a hard time seeing them tosted already unless the motor was REALLY running rough.... and you prolly wouldve noticed that.

This project is far from over

babyblueMX3 · Post by **babyblueMX3** » September 15th, 2005, 10:04 am

I can still run with the car easily but burning oil like crazy. I can even boost again at 20psi but with clouds of smoke. BUT I play things safe and parking the car. Tuning car destroy an engine fast even if it's brand new

Damn that sucks, yea dont run the motor anymore! Doesnt it suck how a minor mistake cost so much money?
