Superchargers
With all the different superchargers available these days, choosing the best supercharger for your particular engine can be a bit of a challenge as no one supercharger can be described as "The best". All superchargers work well, and they all have their strengths and weaknesses. What you need is an idea of what you want from the supercharger and an idea of what to expect from each type of supercharger. Especially as different vehicles and different engines may benefit from one type or another so it's important that you know what you're looking for.
There are two types of superchargers that are commonly used on internal combustion engines:
- Centrifugal superchargers, which are very similar to a turbocharger; and
- Positive-displacement superchargers, such as the Roots supercharger

Turbochargers
As a forced induction system, a turbo is nothing more than an air pump that is driven by the engines exhaust gasses. It consists of a compressor-wheel and a turbine-wheel that are connected by a common shaft. The compressor increases the density of the air that enters the intake manifold by forcing more air than what the engine would normally suck into the manifold. This higher intake air density than produces more power when combined with the correct amount of fuel. This is similar to the way NOS allows more fuel to be burned by providing extra Oxygen as explained by Ian. The major difference between NOS and a turbo is that the turbo provides a constant supply of extra Oxygen while NOS only provides a limited supply.
- You can buy an OEM turbocharged car such as a Mitsubishi 3000GT, a Nissan 300ZX, a Nissan Silvia spec-R, a Toyota Supra, etc.
- You can buy an aftermarket turbo kit for your car. Here there are many options to choose from. There are Garrett turbo kits, STS turbo kits, Turbonetics turbo kits, and so much more.
- You can also build you own turbo system.
There are a number of things you need to consider when selecting a turbo. These include:
- Engine capacity
- Number of valves
- At what RPM to you want the turbo to come in
- The type of fuel you plan on running
- The turbo boost you plan on running
- The amount of horsepower you want.
