I beat a GTO, the 350 hp 04 5 speed version on engine twice and he was modded with headers, after cat exhaust and a cold air kit with stock tires. I have nitrous but he wouldn't race me with it. I have 03 gt w/3:73's, mickey tompson drag radials(they wear out fast, but man do they hook) 75 mm throttle bottle, c&l intake elbow, bbk cold air, 80 mm mass air flow, chipped and a short throw shifter. First gear pulled a car on him everytime on the launch and he never gained after that. He had the power, but those things are suppost to be heavy and he had to be either launching soft or spinnng cause I ate him up out of the whole.
