TC Fab Upgraded Supercharger Rotors

Spinning the supercharger much faster than stock yields a huge increase in horsepower and torque but usually shifts the entire power curve to the left.  The horsepower peaks at a lower RPM than it did stock.  These rotors increase the efficiency of the supercharger at high RPM and allow the engine to make power out to 7000RPM.  Power increased by 25rwhp up top with no losses anywhere on the TC fab test vehicle.

Tuning not required but recommended.
