Ok, I know street racing is looked down upon, but I'll tell this anyway. Coming back around 1:30 am last night and run into a bunch of cars. An integra, cougar, maxima, and some other ricey thing. Raced them in 6th and easily won. Now the fun comes, a little bit after that there was a newer GTO (dual exhaust in back). We were going like 105 and pulled up next to each other. Put it in 5th, and floored it. Well we all know the outcome, but I redlined 5th and reached our speed limited 145ish and he just blew passed me. And kept going. So yea, we all knew what was coming, but wow it was so fast. So how can I improve that top end?
