If we could get a REALLY good driver behind the wheel of one of those Turbo cars I think we would see 12's out of a few of the cars here. It might help if they didn't blow up...

I do think that there are a few cars that are capable of 12's with a little more work. But, traction is the biggest issue here...
As Bill (pre98) said, The_Spy_Guy ran a 14.5 with REALLY bad traction issues. Keep in mind, he was running street tires. I think they're Bridgestone Potenzas but im not sure. His car should be capable of a low 14, maybe more but thats probably about it.
