Could I beat a ...
 

new GTO with my mods. I had my first race with one from a roll at like 20 mph and pulled about a car length ahead of him at about 65. It seemed like he had the pedal to the floor but I dont know. It sure felt good to blow by him though.

doubt it..the newer gto's have the corvette engine in them...the 6.0L

o well it was fun anyway

ls1 GTO - possibly, depending on how modded he is

ls2 GTO - no

Anything is possible...

the 04 GTO had 350 HP and 05/06's have 400hp.....they are kinda heavy, but the 05/06's are pretty damn fast dude.....from a dig you might be able to get the jump cause I hear they are hard to launch, plus they have IRS....but once they get up in the power band...bye bye!
