When one is trying to boost the power of one's car and pushing the boundaries one is faced with a difficult choice between bumping up the capacity and remaining naturally aspirated or going in for a supercharger or turbocharger. Each has its fans as well as its own advantages and disadvantages.

Naturally Aspirated (NA) are simpler to run and maintain. They also give the most linear power delivery and therefore more fun and less tiresome to drive (less gear changes). Problem is they are bigger and heavier (for same power output) than Forced Induction engines and this also affects handling.

Supercharging is a relatively easy way of forcing more air into the engine. The supercharger is a pump that forces more air into the engine and is usually run by a belt, like the timing belt. Advantage is that superchargers work well at low RPMs. Disadvantages are that they are not as effective at higher RPMs and they use otherwise useful engine power to run. They are also relatively bigger than turbochargers.

Turbochargers are thought to be a better way to force more air into the engine because they primarily use the waste energy in the flow of exhaust gases to run. They normally give a bigger increase in torque / power than superchargers. Disadvantages are that they complicate the exhaust system and heat the charge necessitating an intercooler to cool the air that goes into the engine. Turbos are difficult to install and need complicated plumbing for oil etc. and are more difficult to maintain. They are effective at higher RPMs but not at low RPMs but that is fast changing with new innovations in turbo design.
