Took the Z06 down to US41 yesterday (car club I'm a member of rented it out for the day.) It was in the low 90s, and SUPER humid, so I wasn't expecting much. The car was feeling poochy (to me anyways) so I figured if I could run the same times as I did when the car was stock (and in cool weather) then I'd go home a happy camper.
Needless to say, I was a little happy when I got the slip (was dancing in the drivers seat while coming down the return road /phpBB/images/smiles/icon_smile.gif ). I can't remember what the actual correction factor was, but they said with the weather, it was the equivalent of racing at 4500' (local tracks here are ~1500' ) The car was VERY consistent... out of 12 passes, 8-9 of them were 12.4x's in the low 117s (had 1 12.2, one 12.6, one 13.5 and one 16-something - clutch got hot and wouldn't let me into gear ) But all-in-all, not bad considering the car is stock aside from an intake, long-tube headers, and pulled cats. I'm wondering what some of the small stuff will get me (ported TB, TBB, new plugs/wires, etc.) along with some cooler, less humid air.
