I dunno, I've had engine setups that wouldn't see op-temps below 230*F. This one's never seen even that high, so I'm not worried about it.

Those hood vents might work, but now you have to consider air volume of the flow, to make sure that you're not attempting to compress the flow to get it through the vents, otherwise, you're just wasting HP to needlessly compress air.

You're also not really increasing underhood temps that much, because you're still flowing air some, but the engine's coolant is almost always hotter than underhood ambient temps, so there's no reason to fear the air temp increase under the hood.

Since the inside of the hose is always hotter than the outside, raising the outside temp shouldn't be too much of a problem.
