what do you think the best time I can get with a 1998 z28 m6 camaro it has slp lid, slp bellow, ssra intake, pro 5.0 shifter, 3.42 posi on street tires.

 

Good temp and track conditions chould get you low 13's for sure...if you can drive. 12's are possible...but very very rare for stock or close to stock LS1 6 speed cars.

I got a 13.1 @ 107 on a g-tech when I had a Lid and a flowmaster cat-back.

With My Long tubes and ORY I should be 12.7-12.8 range...with good temp and track conditions.

 

high 12's to low 13's...all cars run differently

 

13.5 @ 105

 

Buddy of mine has those exact same mods, except he has a 00 Z28. His best time was a 13.45@106.xx with a 2.2x 60' on street tires w/an M6. The temps were good and the track prep was great.

 

I Ran A 13.33 @105.5 With A 1.97 60 Ft And Mine Is A Convert And Have The Same Exact Mods And My Car Also Weight's 3,856 I Need To Put It On A Diet :d

 

It really depends on how good your tires are and how well you can drive.

Bad tires can make the best driver look like a rookie.
A rookie driver can make the best car look like a Mustang!

If all things go well for you, you should hit low 13's.

 

so, did you ever make it out?
