Bill,
You can hit 150 mph at around your 6000 rpm rev limit. Change the gearing in your ZF to 3.77:1 and 170 mph "may" be obtainable if your motor & it's sub systems are up to it.
The rules for the air strip read anything above 135 requires a roll cage, and you have to have competition seat belts (harness) regardless of your speed.
Sounds like fun.
Your bud on the DTBB, George
