WRX has a touch over 700awhp (useless bhp) and the VR4 has a touch over 600awhp (very usable bhp). Also, the VR4 has bolt on turbos that you can literally bolt on to where the stockers were, upgrade fuel, tune and go. VR4 is also full weight on stock cams, heads, pistons, and bottom end with over 100k on the motor.
Matt Monett's DR-750 turbos were used in this run. VR4 shuts down 3/4 the way through as he was not doing the full KM (just over 1/2 mile) that run.
Enjoy.
