Ive heard roots superchargers are not efficient, how is the HPS system different?
Traditional roots blower design is old engineering, and admittedly is not very efficient, but engines designs from that era were not very efficient either. As engines have improved over the years so has roots supercharger design. The Magnuson, Inc./Eaton supercharger is a hybrid-roots blower pump, with substantial design improvements. The rotors have a unique involute lobe shape and are engineered to a specific L:D ratio. Each rotor has been twisted 60 degrees to form a helix. The two counter rotating rotors have three lobes, which intermesh during operation. These twisted rotors, along with specially designed inlet and outlet port geometry, seal timing, and axial air flow help to reduce pressure variations resulting in a smooth discharge of air and a low level of noise during operation. This arrangement significantly improves efficiency over traditional roots superchargers and reaches a volumetric efficiency near 98%. Magnuson Products, Inc. applications have an adiabatic efficiency t
