Turbo, one of the coolest words to put on the back of a sports car, Turbochargers work on a very basic principle of forced induction.

The Otto Cycle: Or 4 Stroke cycle of an engine involves Intake, where the engine draws air or "Breathes", Compression, compressing the air to a higher temperature, Ignition, the explosion, and Exhaust, expended high pressure air leaving or the engine "exhaling". Turbochargers focus on the last stage of this cycle with engine exhaust.

Turbochargers take the waste exhaust air from the engine and uses it to spin a turbine which takes in more air and pushes it back into the engine. The more air available for the Fuel/Air Mixture the more can be burned thus increasing the speed of the engine. The amount of this air being pushed in by the Turbo is measured as psi. Because they use a turbine, Turbocharged vehicles make noises similar to jet engines depending upon its stage.

Intercoolers: Taking in more air and forcing it back into the engine also causes this air to become hotter. Too much hot air inside of the combustion chamber can cause spontaneous explosions also known as engine knock. This can cause increased wear on the combustion chambers, to avoid this cars equipped with Turbochargers also have a device known as an Intercooler. The Intercooler chills the air being forced into the engine from the turbo before reaching it.
