What are the types of superchargers?
2 Answers
There are three types of superchargers: centrifugal superchargers, Roots-type superchargers, and screw-type superchargers. Centrifugal superchargers are similar to turbochargers, except that they are not driven by engine exhaust but by the engine's belt. Their principle of pressurization is the same as that of turbochargers, where air is drawn in and pressurized by centrifugal force to achieve compressed air. Roots-type superchargers draw air into the supercharger, where two helical blades compress the air before sending it to the intake manifold. Screw-type superchargers are derived from the basic type; when air is drawn into the supercharger, it is forced into the intake manifold by helical blades. This type of supercharger is very effective in increasing horsepower across all RPM ranges.
Having been into cars for years, I can tell you that superchargers mainly fall into three categories. The Roots-type supercharger is the most primitive and common, like the one used in the Ford Mustang GT500. It delivers insane low-end torque, making acceleration lightning-fast—perfect for stop-and-go city traffic, though it's less efficient and thirstier on fuel. The Screw-type supercharger, found in some high-end sports cars like Lamborghinis, compresses air more efficiently and quietly, with linear power delivery and zero lag. However, it's complex to manufacture, pricey, and requires extra cooling to prevent overheating. The Centrifugal supercharger resembles a turbo but is mechanically driven, unleashing jaw-dropping horsepower at high RPMs—ideal for performance builds, though throttle response is slightly slower. Choosing one boils down to trade-offs: Roots for daily convenience, Centrifugal for track thrills, and Screw for balanced refinement. For maintenance, regularly check belts and oil to keep your supercharger from calling it quits.
