Supra is definatly slow… my 04 750 went 10.8 on my 1st pass ever on a bike, im sure the 1000 is definatly faster with 30 or so more hp. Id like to see your car race a gsxr-1000 with a good rider, since you are a good driver yourself. Are you sure it was a 1000 and not a 750, lol… Id put my money on the bike, you car is fast no doubt, not to take anything away from it, but I dunno man, I beg to differ back.
And to IROC… a T88 is a small turbo compared to the street trim turbos people are running on Supras these days.
