The most common types of supercharger based on design. This includes Roots, Twin Screw and Centrifugal types.
A centrifugal supercharger uses centrifugal force to push more air into the engine.
Also Known As: Blower
A Roots blower draws air in using outward spinning rotors that pump the added air to the engine.
Also Known As: Lysholm, Rotary Screw, Twin Screw
A Twin Screw supercharger, like a Roots blower, draws air in with spinning rotors but is designed to compress air unlike the Roots system.
Also Known As: G-Lader
The Scroll supercharger uses two scrolls, one fixed the other moving, that draws air from the open end of the spiral and compresses the air as it moves to the center spiral.
Also Known As: Rotary Vane, Sliding Vane
The rotary vane blower draws air in and compresses it between the blades before delivering it to the engine.
