Even driving conservatively, with half way decent driving it should still be able to break mid 12's unless there's something way wrong with the setup, like really bad tires, poorly prepped track etc. Yeah, there is more to going fast than power, there are guys in Vipers and Z06's that run mid 13's, certainly not remotely close to the car's capability. But it would take some pretty bad driving for an outcome like that. The difference between traction/shifting should mean it runs 11's or 12's, 12's or 13's would = really bad driving or a major problem somewhere(ie, bald tires, bad track prep etc). I'm ASSUMING the OP's setup is adequate for the power and he's at least an ok driver. In the end, it runs what it runs though. My money's on mid-low 12's driving conservatively.
