LS4 Performance - 08 Grand Prix GXP 1/8th mile times.

Whats everyone running in the 1/8th with the front drive LS cars? I only got one run in before I got kicked out because I was wearing shorts:jest: Ran a 9.45 @ 78.5 on street tires only mod is magnaflow catback. Had a crappy 2.56 60' lol, due to wheel spin and the traction control still kicked on a little even though I hit the button. I was pretty impressed, seeing where if I could have gotten the 60' down to even a 2.0-2.1 it should have run an 8.90-9.00:burn:

I ran 9.2 bone stock with slight traction issues and bad 2.4 60s.. With traction.. Good tires or low psi.. These cars will do 9.0 I talked to a guy that i believe ran 8.9 with just running 17psi and like 1.9 60ft.. Forget his name. Could look in my inbox if you wanted his advice or whatever

I ran a 9.156@ 78.83 on my way to a 14.19 @97.22 essentially stock with only a Lew tune, with a crappy 2.181 60' time.......... That WILL improve later this spring when I go back to the track!!!

Look in the 1/4 mile sticky.

8.60@82.4 with a 1.96 60'

8.2@87

I ran a 9.5 @ 73mph with cat-back only. That was at +5500 DA though.
