Superchargers

 Pros:

•Increased horsepower: adding a supercharger to any engine is a quick solution to boosting power.

•No lag: the supercharger’s biggest advantage over a turbocharger is that it does not have any lag. Power delivery is immediate because the supercharger is driven by the engine’s crankshaft.

•Low RPM boost: good power at low RPM in comparison with turbochargers, which need to build their boost from exhaust pressures.

•Price: cost effective way of increasing horsepower.

Cons:

•Less efficient: the biggest disadvantage of superchargers is that they suck engine power simply to produce engine power. They’re run off a belt, gear, shaft or chain connected to the engines crankshaft, so you’re essentially powering an air pump with another air pump. Because of this, superchargers are significantly less efficient than turbochargers.

• Long Term reliability, as with all forced induction systems (including turbochargers), the engine internals will be exposed to pressures and temperatures above manufacturer specifications, which can affect the longevity of the engine. You will want to make sure your vehicles engine can handle the increases load before you upgrade and if possible it would be best to build an engine from the bottom up planning on handling the increased pressures.
