Believe it or not........a 'hot engine compartment' is somewhat of a myth.
Besides the IC, there just isn't much in there to create heat - think about it for a bit.
Hobie brings up a good point whether he knows it or not - and that is:
A fan which pushes air UP and out through the tail. Yes, that's right. Virtually no high pressure exists in this outside-of-the-tail area. If one could rig up a set of fans to push air from, say, the bottom of the IC and up through the IC and leave the rest of the tail open........every component 'wins'. Cooler air for the engine heads, pistons, and cylinders - and efficiently cooled air for the IC.
