Hi guys.

It is a proven fact that water is over 14 times more efficient than air at heat exchange.

I do see very much what your saying Craig, for sure mate. And your right.

What your talking about, is the efficiency of the entire system. Compared to a air to air, you dont have unlimited quantities of water to use for it and then you have to extract the heat from the water.

Weather or not it is better in circuit racing where you will be driving for long distances, depends on the efficiency of the entire system.

Interestingly, drag racers with one pass holeshot intercoolers have over 100% efficient water to air intercoolers.
