Its not a real issue so long as the temps don't get out of control, and coolant isn't boiling.

Lets say your supercharger at 2000 rpm sucks in 100CFM of air and right after the supercharger the air is 150 degrees F. Also assume that the volume of air in the intercooler and intake manifold is 3 cubic feet. Lets also assume the same mass of air is going to be flowing out the supercharger regardless of temp or pressure exiting it.
If you take the same mass of air and cram it into two containers that have 3 cubic feet of space and cool one of them, the one that is cooled will have a lower pressure.
It takes less work to compress 100CFM of air to a lower pressure than it does to compress it to a higher pressure.
Also cooler air will reject less heat to the block during the combustion process keeping energy in the gasses so you can extract power from it.
Also note I don't buy into these claims about a warm air intake. If engines burn 98% of all the fuel that goes into them the maximum improvement they could get would only be 2%. I can assure you though they are not getting that.
