How does an HPS supercharger compare with a centrifugal supercharger?
A centrifugal supercharger is essentially a belt driven turbocharger. Centrifugal superchargers systems frequently have less horsepower and torque than the naturally aspirated version of the same engine at lower rpms. There is a narrow rpm band where an centrifugal superchargers perform well but this makes them peaky. The peak horsepower from this narrow band is what centrifugal manufacturers advertise but most experienced people say that the true measure of a supercharger is performance at all engine rpms. Magnuson Products, Inc.s roots hybrid positive displacement superchargers deliver additional horsepower and torque right off idle and maintain horsepower and torque gains through all engine speeds. With the standard integrated bypass system Magnuson Products, Inc.’s are less parasitic than centrifugal.
