cooler air = more power?

This is a discussion on cooler air = more power? within the External Engine forums, part of the LSx Technical Help Section category; No it's not. Your talking about free flowing air compared to compressed air. That's why the intercooler is there. When ...

    No it's not. Your talking about free flowing air compared to compressed air. That's why the intercooler is there. When you compress air, it gives off heat.

    Wikipedia
    Turbochargers and superchargers are engineered to force more air mass into an engine's intake manifold and combustion chamber. Intercooling is a method used to compensate for heating caused by supercharging, a natural byproduct of the semi-adiabatic compression process. Increased air pressure can result in an excessively hot intake charge, significantly reducing the performance gains of supercharging due to decreased density. Increased intake charge temperature can also increase the cylinder combustion temperature, causing detonation, excessive wear, or heat damage to an engine block.

    I've seen turbos put out 240+ air intake temps without intercoolers

    I realize that compressing air increases heat, but along those same lines, the majority of heat exchange comes from the turbo itself being super heated and the connected tubing being hot also (Both Heatsoak).
