very very good point. no matter what numbers u say ur shee has theres always gonna be that one asshole who says his 450 is that much better. so with that said as long as u go out there and race him and win, it doesnt matter. BUT with a 13 in the front (guessing 41 in back) u prolly get 60 or 65. im at stock gears and im at 70 or 75ish. and ive learned that more engine only makes u get there faster.
