Magnuson GM Truck and SUV Supercharger

Cadillac, Chevrolet andGMC Trucks and SUVs, realize gains of 120hp and 120ft-lbs of rear wheel torque!

The genius of this design is the 180 degree rotation of the supercharger to better deliver a straight air path into the supercharger inlet... reducing pumping losses. This unique air to liquid intercooled system is integrated into the manifold and utilizes the proven Magnuson MP112 supercharger... that features a unique internal bypass valve that dramatically improves drivability and extends reliability. Depending on the presence of aftermarket products and engine condition, expect power increases of 120hp and 120ft-lbs of torque.
