I just bought a 98 Z28 Ls1. The track that i usually run my cars at just closed so i need a lil hel on what this car could run. It has an slp loudmouth exhaust and a K&N intake on it. Its an automatic also. Anyone know what this could possibly run?

 

You didn't specify gears, but you'd probably be somewhere in the mid 13's to start with.

 

Yeah, 13.5 would be my guess.
