Comprex Superchargers
A comprex supercharger is a type of forced induction device used to increase the power and efficiency of an engine. Unlike a turbocharger, which uses exhaust gases to create pressurized air, a comprex supercharger uses mechanical energy to pressurize air. This type of supercharger is typically found in high-performance engines and often features variable compression operated by an on-board computer. It is designed to spool up quickly and deliver large quantities of pressurized air.
The comprex supercharger was developed in the 1970s by a team of engineers led by Robert K. Johnson. It is based on the Roots type blower, which was invented in 1854 by Philander and Francis Roots. The Roots type blower was initially used for industrial applications, such as pumping air and gas.
Unlike other types of superchargers, the comprex unit does not need complex drivetrain components to generate boost. Instead, the comprex unit utilizes a set of counter-rotating lobes or vanes. The vanes are connected to a crank shaft, which turns at a significantly higher RPM than the engine. This causes the unit to generate a large amount of pressurized air.
The air is then compressed using a series of one-way valves, which ensure that the air is transferred to the intake manifold with minimal turbulence. The compressor housing is usually made from aluminum or steel and is designed to create a smooth air flow, reducing the amount of noise generated by the supercharger.
The comprex supercharger features an on-board computer that operates the variable compression. This allows the user to adjust the boost levels according to their needs. The amount of boost can be dialed up or down to achieve the desired performance. The comprex unit also features an adjustable bypass valve which can be used to reduce the boost if the engine is put under severe stress.
The comprex supercharger is a popular choice among those seeking to increase the power and efficiency of their vehicles. With its ability to spool up quickly and generate high levels of pressurized air, the comprex unit can provide an extra edge for those looking to take their performance to the next level.
For decades, comprex superchargers have been used in many different types of vehicles, from high-performance racing applications to everyday transportation. This type of supercharger provides a reliable and efficient way to increase the power of any engine.
