i'll be running a 1997 GT 5-speed, with 3.73s and a Flowmaster cat back with no rear seat or spare/jack.....plus I live in CO where elevation slows us about 1.5-2 seconds compared to sea level.....any ideas what I'll run using this combo, I was thinking low 15's maybe high 14's. thanks

 

That's a pretty good guess, it's really hard to predict what someone will run. There are so many variables that come into play. Not to mention driving skills or lack of.

 

good point, pretty much i will be slow since it's my first time and elevation sucks

 

15.5...i see alot of races here and your non pi gt with just gears..at 5000 is gonna be high

 

Whats the altitude at your track?

 

mile-high!

 

Depends a lot on your driving? but with good driving up here mid to high 15s!
