IMHO this will become the cooling system of choice.

Hey; calm down already!  Aside from being ugly, high drag, and very
vulnerable to a stray rock kicked up by the prop nose wheel . . .; well,
it is cheap and simple.

Who says it is high drag?  I suspect it is no more drag than a P51 scoop
duct and exit slot. In fact I will wager you won't be able to measure
the difference.

With gup (composite) side plates it does not have to be ugly.
You can't even see it unless you get down on the ground.
You can always cover the bottom with fine mesh hard ware cloth to defeat
the rocks.

Another subtle advantage is the rad can be almost any size with no need
to limit the frontal area due to cowl space limitation. You can have a 
modern high efficiency thin rad as wide as the fuselage and three feet 
long. It comes as close to having skin surface radiators as one can get.

The more I think about it the better it looks.
