I had part of a broken 280z hood scoop/duct that broke off a few years back when I dropped it. I was bored and decided to fit it to my hood for a little fresh air under the hood, one way or another ;-)
I need to attach some strings to it and see what this scoop actually does since I kinda put it on blindly.... What I am thinking is that because it creates a suction when air is moving over it that when I am moving it will bring air "in... and then it will act as a "vent" when the car is parked/standing still.

That vent will pull air out of the engine bay, even at highway speeds. If you look at old aerodynamic models of the SQ that is a low pressure area of the hood, even on the Z that it came from. I have the complete vent in my hood. Drastically reduced under hood temps.

Ya, this seems to be working really well. I also have my air filter positioned a little further in front of the scoop and down by the stock air filter location so it doesnt get in the way of the air flow and rain.

Cool hood vent. I'm about to do one aswell. This FL heat ain't no joke. Gonna hit the j yards for one hopefully. If not..anyone know a good place to buy them like eBay ect?
