11psi pulley, exhaust, and some gauges. From a stop i lost by a couple of cars. From a roll it was pretty even, he might have pulled a 1/2 car or so. Bet he was runnin about 300 hp at the flywheel.

damn i need a supercharger......wind up toys are good!

 

Yea those things have a ton of torque down low. Once you mod that pulley, that is one fast car.
