Edelbrock Supercharger
 

I recently had an E Force Stage One Supercharger installed by the folks at Watson Racing. Excellent product and excellent results. 2010 GT Premium...8000 miles...4.6/3V. Runs great, plenty of power on the pedal at all times. 452 RWHP/425 RW Torque, with the supplied tune and pulley. Very pleased.
