Hi, im new to ls1 camaros and i just got a 2000 z28 a4 (178k) its got a borla cat back, all the intake crap(slp stuff) minus the MAF,cat delete, nitto drs and i think that is it. I took it to the track saturday night and ran faster and faster...on the last run it did a 8.31 @ 85.037 1/8 on a 1.987 60ft(trapin like 109-110 in the 1/4 no times though) what kinda hp ya think im makin and is the car runin good for the mods or not?

 

Man, that's a lot of miles, does it rattle and squeak real bad?

If your trap speed is 110MPH through an A4, I'd say you're making about 340RWHP. Does the car have headers or an aftermarket camshaft?

 

No, it just has the mods listed(i think)... doesnt squak or rattle at all. The quarter mile speeds are not really reliable i dont think b/c(should have put this in first time) its measured off on the street and its got a slight hill through half of it and actualy its goin like 117 through there but i dont know how it could give me like 10mph its not that much of a help a well just foreget the 1/4 mile stuff...
