cooling a cast iron intake to the point of making frost

Thirty years ago before knowing much, I could build horses into a motor by cooling the air and upping the fuel to match! A engine built from scratch with all the cooling tricks I could come up with! By running a 75 percent reduction on a tricked out stock water pump, I added a few horses by reduction of drag on all the driven parts! A special 4 blade fan design to move the air at low speeds was needed! A 150 degrees on a .066 350 engine with a few oiling tricks as well as coolant solutions with vaporization of fuel to put frost on a cast iron intake at 150 degrees engine temp. using pump gas! My flow was through the roof and needed way more fuel to match! A bit hotter in the cylinder with all that cold air, it leaned quickly if not kept under control! No upgrades or tricks applied to the intake itself was used! I have seen them sawed with aluminum plates added between the coolant's ft. ports and intake runners or stainless heat and oil shields underneath for extra cooling that helped! Vacuum vaporizing the fuel at a low engine temp and giving the expansion rate a boost once heated by compression and combustion sent more horses towards the checkered flag! I have never had a aluminum intake do this as it absorbs heat from the engine! Some of the extra horses from running alcohol is because of its refrigerating most easily! What ever it takes to make this happen yields more horses cheaply by design! It will be worth the effort and time you invest to gain these extra horses!
