I just thought about - the cowl induction hood was designed to create a high pressure area at the base of the windshield - in an effort to force air IN TO the underhood engine. Of course - it was sealed off and connected to the carburetor used at the time. But many don't actually use that anymore so that "sealed" area is gone.... but the high pressure area remains.
The vents are made in an effort to pull air out of the underhood area - yet we're asking the same hood to force air into the area. It would be interesting to see the airflow in a wind tunnel!!!!! LOL
We know these work - because others have seen the results of adding these to their hoods. I just got a kick out of the thought.

This is a great point Greg. I think these vents are probably actually most beneficial when the car is standing still or going slow, in traffic, etc. where heat just pours out of 'em. Would be interesting to see some IR photography and windtunnel work... but that's beyond my resources!
