has anyone bothered to measure the air pressure in the engine comapartment at the speed people are seeing the hood lift?
A simple magnehelic pressure gauge is all that is needed.... Seems prudent before trying to design a solution to reduce positive pressure in the engine bay Since it may actually be lift causing the hood to flex rather than pressure in the engine bay.
Plus if it would provide a means of measuring how effective the designed solution is. And it turns out that the engine bay is not under positive pressure you could use the side vents to reduce pressure in the wheel well instead
