Depends on the engine rpms. my car trapped 135 mph with a 3.90 gear, 26 inch tall tires, around 6800 rpm at the end of the track. This is with a final trans ratio of 1:1.

First you need to figure out what will be your engine's max rpm? Then pick a gear and tire diameter so that it hits the max rpm at the target trap speed.
