Turbo and supercharging have been crucial in modern automotive performance. These induction add-ons help your small displacement 4-cylinder punch above its weight class or help your monstrous V8 achieve ludicrous speed. In any case, the process of forced induction heats your charged air, which is less than ideal for keeping your performance machine, well, performing. Intercooling systems have long been implemented to mitigate this issue, but as these systems evolve, things can get a little convoluted, which is why we're here! Let's dig in.
To start, we need to understand the fundamentals of how a forced induction system works and why that leads to hot intake temps. Your turbo or supercharger is, in essence, an air compressor. The concept behind forced induction is to cram more air into your intake system than the ambient air pressure allows. Naturally aspirated engines are limited to the atmospheric pressure of the
