lol, just for a laugh.
Active cooling for inlet flow on an NA is possibly quite useless.
Sure, you could use water to cool it, but you'd need a massive surface area to exchange heat, otherwise a matrix jsut becomes a restriction. After that your left with the dialemma of how to cool the water you'd heated up....radiator you say...sure, but thats being cooled by the air outside so will only ever reach current air temps, which is what you would be starting with in the first place.
Second is the intercooler, again, your just increasing complexity of passing air through a cooler which has air of the same temp on the other side.
All assuming that the rest of the inlet tract in both of the above adds zero heat energy to the air, then you get to the inlet manifold which is attatched to the head and made of ally, a great conductor of heat.....so all attemps being wasted.
Isolate the heat transferred into the manifold via the 100+ deg cylinderhead its attatched to and you'll probably net more gains than active cooling.
And before anyone suggests liquid gas cooling lol.
thats it, i'm going to bed.
