I love those modified Supras. Those 900+ horsepower ones. I raced one on the highway and it put buses on me immediately(I was running all motor h/c at the time). Then, they go to the track and run 13s and high 12s all day, lol.
The fastest I've ever gone in my ls1 TA was around 155 mph on Alligator Alley(yea, very stupid, stupid thing to do), racing an ST1 of all things.
Besides, who the fuck still has a stock LT1 car, especially if they race it? Yes, they are a bit of a dog bone stock, but it takes very little in mods to make it run deep 12s/high 11s. Hell, there are cam-only LS1 f-bods that run low to mid 10s.
