Thought about that my self, decided the cooler clutch was a better (scoop on left side, less wind) this nose to tail racing is hard to get use to. We not only deal with the plate,we also have a gear rule 13/59 and a rev limit. Having to teach drafting to eight yr old. Back to the scoops some people tie the air hose real close to carb to keep engine cool!! who knows. Try waxing,good coat of wax makes a slick car might be worth a tenth . T. Worthy
