my jetta would do 160 with an intake, it was a 98 glx vr6 all stock cept for the intake, those cars are fast right from the factory, i got busted for doing 130mph in a 70 on the interstate and i was just on my way home coming down from 155, and believe me he prolly had more rpm to go, cuz the power band on that car is hellacious, if you were doing 160 he prolly had about a grand more rpm to go before he hit the redline, and then you still have some power.
