When traveling at about 60 or above I get so much air pressure under the hood that I feel like it might blow the panel right off. the only areas where the under hood air can escape are the opening directly below the engine, the header opening, and a cut-out in the hood for the engine. As well as a narrow driveshaft tunnel (BEC). None of the openings are oversized. They are all just large enough to get the job done. The surface area of the inlet in the nose is no greater than the surface areas for exit, but still... the air seems to build under the hood, like a baloon. When driving at speed, I can see the rear of the hood lift up where it meets the scuttle so the air can escape. I'd like to equalize this pressure, so the hood dosent want to fly off. how have others delt with this issue. I'd like to avoid cutting up the hood, but if i do, I'd like advice on the most efficent opening that will draw air out.
