Let me do a little searching, I may have a cool vent idea for you. A guy from one of my other forums (Chevelle-El Camino forum) built some cool, functional fender vents on his car. They looked clean, sporty and his vented underhood heat, but it could be easily relocated/ ducted to vent high pressure air. They could look pretty sweet, but require some cutting and bodywork.
