total B.S.

This guy in my english class just got a 88 RS camaro. and all he dose sense he got it is talk **** about how his car will whoop on mine and how he wants to bet me money when we race. (dont get me wrong i will race him) I dont know my camaros but he was saying that he got a dyno test and the machanic says he has 290hp. i dont think a rs with a chip and exaust can get over 225hp. and when i asked him how much it cost he said 30$ for the dyno and when i asked to see it on paper, he then thinks his mom threw it away. basically what im getting at is i now that i can beat him. I'm just tired of his crap and i need some amo that will shut him up. untill his car gets out of the shop from being worked on (imagine that his camaro needs some work for the third time in under a month) and he has had some time working on his 5 speed.
