Intercoolers

Cool air contains more oxygen molecules than warm air does.

Both turbochargers and superchargers require additional cooling of air and or oil. This is because these power boosting devices create additional heat. Intercoolers provide additional cooling of the air before it enters the combustion chamber. This cooled denser charge increases the engine’s horsepower. As air heats it gets thinner. This means that there are fewer molecules of air in the charge. By cooling the air we increase the number of molecules in the air charge. This increase in air molecules increases horsepower and prevents detonation.

Intercooler

An intercooler looks a lot like a radiator placed near or on top of the engine. It may be air cooled and or water cooled. They’re found on both turbocharged and supercharged engines.

Performance engines stress and prematurely wear the engine oil as well. Most supercharged and many turbocharged applications require an oil cooler as well as an intercooler. Many parts on these engines must be reinforced to withstand these additional cylinder pressures.
