A turbocharger, or turbo is a centrifugal compressor powered by a turbine that is driven by an engines exhaust gases. You can also reduce the pressure drop in the intercooler, which allows you to run the same boost in the intake manifold while while having a lower turbo discharge pressure. For an intercooler, the ratio of the thermal capacities of the heated and cooled fluid may be significantly different, and thus the ratio of thermal capacities for intercoolers could as low. As the air cools down, its volume shrinks, so the amount of fuelair mixture fed to the engine and hence the power output. Its benefit lies with the compressor increasing the mass of air entering the engine forced induction, thereby resulting in greater performance for either, or both, power and efficiency.
