I used to won a 99 with a flowmaster cat back..........

Before I modded her, thats about what I was running....

I was about to get her down to a 14.80 timeslip before I sold her......

Re: ET question

Try launching off idle, get your 60' down to the 2.1's. You will probably see high 9's in the 1/8th and 15.5's in the 1/4.

Re: ET question

2.1 60's arent really possilble with open diff and 3.08's though. MAYBE high 2.2's but 2.3's is about the best I've seen with exhaust and stock rear end.

Re: ET question

yea my best 60 was a 2.2 and i pretty sure my stock rear end has a lsd
what would it be with a 3.73?
and whats a good launch rpm?

Try launching from idle, each car is different with launch rpm, the best launch you could possible get you will hear just a chirp. If you give it too much RPM, you will spin. If too little, you won't hear anything or you'll bog. Try to find your "chirp" point.
