Don’t get me wrong, my 60’ times aren’t terrible (best of 1.47, average of 1.5/1.6), but they’re holding me back from getting into the low 9’s. And, my local track doesn’t exactly kill it on the track prep too. It’s a pretty low dollar operation. The people are nice, but if the track prep is anything like the bathroom maintenance…. So, I suppose this could be a track issue as much as an issue with my setup. Car trapped 148 last run out, so the power is there in my humble opinion.

So, am I at the point where I *need* to do a 15” conversion? Is that how you get down to 1.2 60’ times? Or is the suspension more important (coilovers)? I’m not sure how many 8 or low-9 second guys are on this board, but appreciate any advice or thoughts from the Forced Induction squad.

When the car and the scan data tell you that you're spinning the tires on the hit and/or down low, or on the 2/3 or 3/4 shifts as mine did. My 305/45/17 ET Street R weren't enough up here much less at Topeka or Vegas, and they might not hold yours.
