Question intercooled aftercooled

I know this is a dumb question but what is the difference between intercooled and after cooled?

Smile Pretty simple actually...


Intercooled simply means you lower the blower/turbo discharge air temperature either within the intake manifold (i.e. Allen Superchargers, '03-04 Cobra, '99-'03 Lightning, etc) or within the intake system itself, by using heat exchangers. Intercooler systems can be either water-to-air or just air-to-air. The belief is air-to-air is more efficient.

Aftercooled is a term that Vortech really uses to describe their "intercooler".

The use of the term 'intercooler' on any single stage boost aided engine is actually not correct. It is a term that has just kind of ‘stuck’.

The term ‘Intercooler’ was coined as an inter-stage aftercooler became a necessary device in the performance evolution of large displacement 2-stroke diesel engines (specifically Detroit Diesel). These 2-stroke engine require a supercharger to operate but were limited in terms of loading and heat rise when boost was increased so the performance solution was to use 1 or 2 turbos whose discharge was then ‘intercooled’ and then fed to the supercharger. So, technically If the cooler is between boost devices it is an intercooler, if it is after the final boost device it is an aftercooler. Powder & Ceramic Coating
