What is a Power Cooler?
An intercooler is recognised as a fundamental of a turbocharger system. It never has been, nor should ever be, considered icing on cake. A proper intercooler is more cake. The intercooler is a radiator - or, more correctly, heat exchanger - positioned between the turbo and the intake manifold. Its sole purpose get the heat out of the intake charge that turbo put into the charge while compressing it.
Removing heat from the intake charge has two huge areas of merit. First, the reduction of temperature. Denser intake charges make more power. Second, but no less important, is terrific benefit to the combustion process brought about by reduced temperatures in the intake charge. Detonation is reduced by any reduction in intake temperatures. These two areas of merit are the reasons a proper intercooler can increase the power and marginof safety of the turbocharged engine.
