Intercoolers explained – Modification Tips

24 January 2012 No Comment

We all know that cold Air carries more oxygen that warmer air. You may have noticed that when air is compressed it gets warmer. With forced air induction engines which us a turbo or a supercharger the air is much warmer than in an engine that doesn’t have forced induction.

Intercoolers work much like the radiator of a car. The cold air from outside is forced through the fins of the intercooler to where the warm charge air is contained. This has the effect of reducing the warm air stored in the intercooler and rapidly cools the charged air. All intercoolers will create drag or slow the flow of intake air coming into the engine, but the benefits of having a colder air charge is much better than having hot air potentially cause detonation in your cylinders.

When designing an intercooler much work goes in to preventing this drag effect this is commonly known as Turbo Lag. The size of the intercooler, along with the size of the internal piping needs to be matched to the requirements of your motor and turbo.
