Lately [when?], centrifugal superchargers have become very common in today's performance automotive world. [3] Superchargers are sometimes installed as original equipment on some vehicles manufactured today.
A mechanically driven supercharger offers exceptional response and low-rpm performance, as it does not rely on pressurization of the exhaust manifold (assuming that it is a positive-displacement design, such as a Roots-type or twin-screw, as opposed to a centrifugal supercharger, which does not provide substantial boost in the lower rpm range), but is less efficient than a turbocharger due to ...
A turbocharger for a car engine A supercharger (on top of a dark-grey inlet manifold) for a car engine. In an internal combustion engine, forced induction is where turbocharging or supercharging is used to increase the density of the intake air. Engines without forced induction are classified as naturally aspirated. [1]
