What Are The Different Types Of Superchargers Available?

Superchargers are classified into three types: Roots, centrifugal, and twin screws. Although each one works in a different way, they all work the same: Compress the intake air and force the fuel into the engine at higher pressure.

What Type Of Supercharger Do You Prefer?

A centrifugal supercharger wins this battle, as it operates with greater efficiency than a positive displacement supercharger, especially at higher boost levels. A centrifugal supercharger will cool the intake air and produce more power for the same boost pressure.

What is a Supercharger? Working, Types, Advantages

If you’re a hardcore racing fan, you might have seen it in NFS and other racing games. What are superchargers? What are their advantages and how do they work?

Let’s find out everything we can about them right now!


These are pressure-boosting devices (compressors), which raise the pressure of air before it can get into the cylinders of the internal combustion engines.

Supercharging is the process of increasing pressure or forcing more air into the engine.

Why Do We Need Superchargers?

Let’s not get into the long, complicated formulas.

The mean effective pressure is what determines the engine’s power. The average pressure inside the cylinder. The average pressure directly affects the power.

Power Mean Effective Pressure (MEP)

Pressure increases during the compression stroke and decreases during the exhaust stroke. These data allow us to calculate the average pressure.

The MEP Is More Efficient Than the Engine

If more air is compressed and forced into the cylinder, it will result in a higher mean pressure. This will lead to more power! They are needed to force air into the engine. They are also known as forced-induction systems.

To force more air into an engine, you need to increase the density of the charge that is being injected into the cylinder. The engine performs poorly at higher altitudes and hills because the air density is lower. Superchargers are required to offset power loss at higher altitudes and for vehicles.

Superchargers at Work

Superchargers are compressors/blowers that take air at normal ambient pressure, compress it, and forcefully push it into the engine. The belt drive transmits power to the compressor/blower from the engine.

An increase in the engine’s mean effective pressure is achieved by adding more air-fuel mixture to the cylinder. A higher MEP means that the engine produces more power. This is why a compressor can be added to the engine to make it more efficient.

Supercharger Types:-

• Centrifugal Superchargers

These are used frequently in vehicles and are powered by an engine via a belt pulley system. The impeller is where the air-fuel mixture goes. The air then passes through the diffuser to increase the pressure. The air finally makes its way to the engine through the volute casing.

• Root’s Supercharger

Root’s type has two rotors with epicycloid shapes. Root’s type has two rotors of equal size, inter-meshed and mounted on 2 shafts. The engine powers one shaft via either a V-belt or a gear train depending on its distance. There can be 2 or more lobes in a rotor depending on the requirements. Air enters the outlet through the inlet and gets trapped. The outlet pressure would therefore be higher than that at the inlet.

• Vane Type Supercharger

The drum of the supercharger is fitted with a number of vanes. These vanes are pulled outwards by pre-compressed springs. This arrangement allows the vane to remain in contact with the body’s inner surface.

Because of eccentric rotation, the distance between the vanes is greater at the inlet and smaller at the outlet. This means that the volume of air entering the inlet is reduced on the way to the outlet. Air pressure increases when volume decreases. The mixture at the outlet has a higher pressure than the one at the inlet.

ProCharger Parts

There are different types of superchargers available on the market, each designed for a specific purpose. ProCharger parts are designed for high-performance applications. They offer a variety of different models, each with different capabilities. ProCharger is designed for use with small engines, while the ProCharger is designed for use with larger engines. Each model offers different benefits, so it’s important to choose the right one for your needs.
