Turbo chargers are a type of "forced induction system". this means they compress air into the engine. a turbo charger allows an engine to basically cram more air and fuel into the cylinders to give a larger "power stroke".
the exaust from the cylinders spins the turbine which is connected by a shaft on the compressor. the exaust gases that come out of the cylinders pass through the turbine blades. the more exaust gas that passes through the blades the faster they spin. the faster the blades spin, the faster the shaft spins the compresser wheel, and the more air is compressed back into the cylinders. most turbo chargers have a "wastegate". a waste gate is valve that allows exaust to bypass the turbine to reduce lag at high engine speeds.
Superchargers are also forced induction systems.. but unlike turbochargers (which use exaust gas to drive a turbine).. superchargers are powered by belt-drive from the engines crankshaft. superchargers are not subject to lag like turbochargers because they are engine driven. the faster the engine runs, the more compressed air the supercharger produces.
lets talk a little about gas turbine engines now. in a gas turbine engine, an engine creates its own gases by burning kerosene or jet fuel. these gases are heated, so they expand rapidly and spin the turbine.
juss a few notes i felt like writing out cuz i wanted to make a blog too. lol... yay for multitasking.
