I hope your idea works. I like the novelty, but every liquid cooled engine on every plane and car I have ever seen had the radiator directly facing the airstream. Unless forced by a fan, I doubt that enough air will pass thru to offer any effective result. Please don't take this as a deterrent, I just want to express my concerns. Best regards in any case.
