Couldn't get better than 2.0 60' this weekend, even dropping the PSI to 11.5.
I have two primary issues I believe.
1) Can't get a good burnout because my ebrake doesn't hold the car back.
2) Tons of low-end torque from a small turbo blows the tires off on launch.
Even slipping, launching off basically idle it spins the tires when I went WOT.
The best 60' times resulted in 4K RPM launches with very little clutch slipping.
I do question the track prep though. I saw no VHT used on the track, and they were bad about keeping the water box wet. (it was a track rental day)
At any rate I blew away my previous best of a 14.11 with a 13.63.
Hopefully next year I can see some low 13's.
