What is the Roots supercharger design theory?
The Roots supercharger is a proven design used for many years by leading automobile manufacturers. The Eaton supercharger used by HPS is essentially a Roots supercharger with precision-matched airflow chambers. Each rotor has been twisted 60 degrees to form a helix. Each of the two counter-rotating rotors has three lobes, which intermesh during operation. These helical rotors, along with specially designed inlet and discharge ports and ductwork, help to reduce pressure variations resulting in a smooth discharge of air and a low noise level during operation. The port and duct arrangement improves efficiency over traditional Roots superchargers. With helical rotors and an axial inlet, the supercharger can be spun to up to 14,000 RPM, thereby reducing package size versus a slower-RPM system. Our systems are designed to integrate seamlessly with the retained factory components and present a clean OEM-like appearance.
