did that while racing a BPU Supra several years ago. In fact if you ever heard of 20/20 Auto Body in LA it was against the owners Supra (Tommy). We did a 40 roll on the upper deck of 183 (here in Austin) at 2am, when I looked down (real quick) I was at 7200rpm in 5th......and had him by 1 car length :) That was the fastest I've ever been in my Z...so far.
