This is a link to a wind tunnel video that is actually USEFUL, versus just the usual puff of smoke over the hood and windshield. Lucky for us, the A2 aero guy was in the tunnel at the time to show the other fella where the important areas were on the car.
There is a '71 SuperBird video I posted earlier much like this one, but this one is
so much better.
Note how that the reverse hood scoops mounted on the fenders are functional at extracting high pressure air from the wheel well at 5:46 in the video.
Also, note how that the air is a mess around the front tires and rear window. It is interesting to see where the boundary is in the turbulent air back there.
You can also see the low pressure area as the guy sticks the wand in the cowl just behind the hood.
