some of the faster turbocharged drag and top speed racers use giant tanks filled with ice water mounted where the passenger seat would be to cool the air charge.. they can convert 50 pounds of ice into 50 pounds of warm water in a couple of minutes..

A question.
Have you ever worked with water/air ICs? Not ice-bath units, but ones with heat exchangers.
The heat exhangers typically are a lot smaller than the typical automotive condenser. (The one on the Toyota GT4 was not much larger than a heater core!) They use coolant as a working fluid. No heat of evaporation utilized, just straight old-fashioned heat exchange. It worked just fine.
I installed a "huge" water/air IC on a supercharged Corvette. The heat exchanger was maybe 12"x24" - not very large. It kept the air temps within 10-20 degrees of ambient when under boost with a 10psi Eaton-blown setup.
So: Are you seriously suggesting that intercooling of any sort is not worth any power?
It is a given that an A/C system works better than standard heat transfer because it supercools the fluid before cooling the air, then superheats the fluid before dissipating the heat. It increases the delta-T across both heat exhangers.
Would this added benefit not be worth the 5-10hp worth of parasitic losses?
