here's what really scary! Our PT cars do this without even a second effort and with LESS safety gear.....This is me at 145 on Michigan International Raceway, in a streetcar, no cage, no driving suit......after that event Jane now has a cage because at 140mph on a 30 degree bank you think about SAFETY a lot, shifting into forth and floored the car will easily surpass 140 but any faster was REALLY scary without safety gear
