If they could use a hood scoop or ram air , I am sure the motor builder would prefer that ?
Charles: How many drag horsepower is the hood scoop vs. the increase in engine horsepower (and at all speeds from, say, 140 mph to 200 mph) ? While the engine tuner might like it, the crew chief might not. Yes, it's true that's what they have to do by the rules, but that doesn,t necessarily mean it's not the best for their program. vic
