I'm sure no one has actually addressed the issue of intake temperature realistically.
Starting with forced induction:
Simply, compressing gas of any description creates heat meaning less density.
The intercooler/charge cooler is there to exchange heat and try and bring down the intake temperature of the compressed inlet charge. Most of these are 40 - 70% efficient in reality.
The problem with this on an n/a engine is that your inlet charge is already ambient temperature. So your trying to reduce the temperature beyond this which a normal intercooler isn't realistically possible.
If your happen to be running your beams in a boat then you can use the water to create a charge cooling system beyond 100% efficient as the water is colder than the ambient air. Even this would probably be unsuccessful due to the restriction across the heat exchanger.
Also any hope of using air con system to cool the charge ha to be run off the engine and simply could not offer the vast amount of air your engine requires
