Supercharger Types

The most common types of supercharger based on design. This includes Roots, Twin Screw and Centrifugal types.


ATI ProCharger Cutaway

Centrifugal

A centrifugal supercharger uses centrifugal force to push more air into the engine.


Cutaway of an Eaton Roots Type Supercharger

Roots

Also Known As: Blower

A Roots blower draws air in using outward spinning rotors that pump the added air to the engine.


Cutaway of a Whipple Twin-Screw Supercharger

Screw

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.


Handtmann HSL Scroll Type Supercharger

Scroll

Also Known As: G-Lader, Spiral

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.


Rendering of a Turbocharger

Turbocharger

Also Known As: Turbo, Turbosupercharger

A Turbo (AKA Turbocharger or Superturbocharger) is a forced induction pump that uses exhaust gases to drive a turbine and compressor to force more air into the combustion chamber.


Cutaway of a Sliding Vane Compressor

Vane

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.
