nested in the center (valley) of the engine, will absorb heat (heat soak) during operation due to thermal transfer from the engine block and heads. Elevated temperature levels in the supercharger directly influence discharge air temperatures that next enter the engine. Higher engine inlet air temperatures result in reduced power increases and an increased likelihood of engine damage resulting from detonation within the cylinders. See also

result is air that is highly pressurized, but that travels at low speed. The high-pressure, low-speed air is then fed into the engine, where the additional pressure gives the engine the ability to burn more fuel and have a higher level of combustion. This results in a faster, more responsive vehicle due to greater engine volumetric efficiency.

Centrifugal superchargers have become popular in the aftermarket as a bolt-on addition to improve performance. By design, centrifugal superchargers allow for easy integration of air-to-air or air-to-water intercooling. Several companies build centrifugal superchargers and also offer them as complete

The centrifugal supercharger draws its power from the movement of the drive where it is attached. At this point, the supercharger powers an impeller – or small rotating wheel. The impeller draws air into a small compressor housing (volute) and centrifugal force sends the air into the diffuser. The

The four main components of a centrifugal supercharger are the volute (compressor housing), diffuser, impeller and transmission. Volutes are typically cast into a form from aluminum rather than other metals due to the combination of strength, weight, and resistance to corrosion. Volutes are then

Centrifugal superchargers are typically mounted off to the side on the front of the engine. Distancing the supercharger from the engine via a mounting bracket greatly reduces heat transfer from the engine to the supercharger during operation. By comparison, a twin screw or roots blower which is

The transmission provides a step-up ratio from the input shaft (driven from the engine crankshaft) to the output shaft, to which the impeller attaches (it is not uncommon for centrifugal supercharger impeller speeds to exceed 100,000 rotations per minute). The basic components of the gear drive
