How Turbo Systems Work
The turbocharger uses wasted energy from the exhaust gas to drive its turbine wheel that is linked to its compressor through a shaft. As the shaft spins, the compressor sucks air through the air filter and forces that air into the intake manifold. As the inlet valves in the cylinder open, a greater mass of air is forced into the cylinder to be burnt with the fuel. Hence the term "Forced Induction".
The extra air forced into the cylinder along with an efficient system design and proper tuning results in a large power increase. By adding an intercooler to the system engine power can be further increased. An Intercooler removes the heat of compression before it enters the engine. Delivering cold air means that there is more oxygen per cylinder (cold air has a higher density than warm air) thus more engine power is attainable.
