Today I raced my friends 98 hatchback with a b16 A1 engine with like 70k miles. he has a full exhaust and intake. we did a 40roll and let me just say i pulled from him more then the cobalt did me lol, i was about 4cars ahead at 100.Then we did a 65roll and i destoryed him again. Makes m feel alittle better now lol. I did hear though that they are way better only from stop, so we have to try it again.
