going to test out my semi-stock setup this coming friday



S4 100% stock rebuilt longblock engine

S4 stock turbo (hits 12PSI) no boost controller

S5 Top mount intercooler

walbro 255 re-wired

Racing Beat full exhaust (old version that came with a 3" DP)

bigger injectors and a FPR

MicroTech ECU



ET street slicks (hoping for a 1.7-1.8 60'foot



12's@105-08MPH?

I might be missing something, but how does exhaust, slicks and tuning turn a 15 second car into a 12 second car?

yah it should run 12's no problem! local car here was doing low 12's with a 2.5" exhaust, tires, and pullies

hey the leaner it is the more power u make, so it would go faster.... till it pops that is...

blah car is slowwwwwwwwwwwwwwwwwwwww

14.1@96 best I could do

even with a 1.8 60' it got a vacuume leake somewhere(heard a big hissing noice) and was only able to build 8-9 PSI tops



oh well

the POS stock setup is going for sale as soon as I rebuild my 3rd gen race motor
