what's the time for a 325i? you should have probably the same power but with less weight!

Not bad...
Plans for other exhaust ?

that seems slow to me? is that really what is expected out of 8psi? are you running an intercooler? and how much would you guess the weight of one of these cars to be?

Sounds slow to me also. I would think you would at least be running in the 13's. Last 1/4 I ran was with a 2.5 liter dodge avenger and I ran a 15.9.

Actulay Guy's it's a good time considering I don't have a tune,slicks, sporting a 2inch exhaust,230k motor, AFR was in the 10s

too shave 3seconds with the above conditions anybody would be happy

I just finished doing my 2.5 exhaust and I can confirm she pulls way harder and builds boost much quicker

i just wasn't aware of what to expect with your setup. i am currently building a turbo m42 to swap into my 1974 bmw 2002 and i was expecting a lot faster time than that so i was a little concerned. i will be running more boost, lower comp pistons, an intercooler, and a piggyback system etc. etc, but i was just wondering for a base to go off of.

with a proper tune,lsd and slicks a e30 on 12psi will do mid 13s
