Gary Hall told me years ago that he had done some airflow tests with

various scoops, and that the "pretty" ones that only come out a couple

inches are only for looks.  The big Earmuffs (or Elephant Ears as I call

them) apparently do get out in the boundary layer.  I tried the old yarn

trick when I used to have them on my car, and sure enough air was blowing

out of the inside opening.
