hood scoops how high and which ones work.

Get a long piece of yarn or thin rope, tape the beginning of it to the very front edge of the hood, and the other end to the edge of the front of the roof. If the scoop opening is not above/in front of that line you just created, the scoop is not working effectively. The exception to this rule is a NACA duct laid into the hood. Air flows over the hood, and along the very top of the hood. That is from the old Direct Connection bulletins.
