aright, here's what i think. . .off the line, the firebird will probly beat you, but as soon as you hit 2nd you should start to beat the firebird. i know the supra doesnt have too good of a start becuz my bro has an 89 turbo. dont go on what ive just said, wait for other people to comment, i wouldnt want to be the reason y u might lose 100 bucks.
