What a Supercharger Does

You might be wondering if adding a supercharger to your car will really provide an increase in performance, or whether it is worth the money. Let’s take a look at what supercharger kits can do for your ride, and what to expect regarding performance after installation.

A supercharger is a forced induction system for your engine, sometimes referred to as a blower. More simply put, it is an air pump driven by the crankshaft which allows for a greater volume of air and fuel being brought into the combustion chamber to provide boost. There are two types available: a centrifugal, or forced induction, kit which acts similar to a turbocharger, and a positive displacement supercharger. Which you choose will depend on your vehicle and what you hope to realize with installation of one of these kits.

A centrifugal supercharger kit is generally used in smaller vehicles which have less space in the engine compartment. It works as a compressor with an impeller wheel which is driven by step-up gears to move maximum air into the engine. This process does not work until higher rpms are achieved, so it will take a few seconds, after reaching 2,000 rpms, to experience boost. However, the step-up gearing means you can still create maximum displacement in a smaller sized unit, making it ideal for foreign cars. These centrifugal superchargers are most like turbo charger kits, which usually cost more.

Positive displacement superchargers are those commonly seen in classic hot rods with the hood raised or cut out to accommodate their larger size. These systems pump air into the intake manifold, but do so at a very high, fixed rate which is proportionate to the size of the supercharger and the engine speed. This means that over-boost cannot occur while boost is experienced instantly. One disadvantage, in addition to size, is the fact that this type of supercharger generates a great deal of heat. Fortunately, you can counteract this effect by installing an intercoolor to chill the air intake. For larger sports cars and racing applications, a positive displacement supercharger is the way to go.

The advanced technology of today’s supercharger kits mean that you may realize nearly double the horsepower from your car’s engine. Many systems claim an increase of 45% in both horsepower and pound feet of torque, while some simply state a 50 – 70 gain in horsepower can be achieved. No matter what results are actual in your vehicle, you are sure to experience highly improved performance.

Look online to find the best prices for supercharger kits and make sure to do your homework beforehand. With the purchase of the ideal supercharger type for your car, you can blow away the competition in speed and performance.
