I'll bet 99% of forum members already knew that hood scoops and cool air ducts improve performance by only a small amount in real world driving.

Since lots of people think scoops look sexy, they aren't going away anytime soon, which will no doubt keep discussions like this one going.

Every NASCAR car that I have seen up close was getting intake air from the bottom of the windshield by way of a carbon fiber air box from the firewall to the carb. I'm pretty sure each and every NASCAR car has these air boxes that feed the carb cool air and supposedly higher pressure air that piles up at the bottom of the windshield at high speeds.
