[DeTomaso] Airflow test # 5/late for work 2012

[Matt]

We'll I don't have any salt flats nearby so we might have to settle for what I can get away with. I'd rather not remove my raingutter completely(one piece) but I think I can simulate something close enough to see what the results might be. Using some filler material and tape to smooth out the frontal impact area is possible.
You'd still have some dropoff area directly behind the gutter so that could affect things but if improvements were realized with proof maybe the ORR guys could possibly benefit.
I like a test that might result in future improvements and this qualifies Jack.
Besides anything for a guy who has given so much of himself for the good of the Pantera community. Thank you Jack (and Judy too!)
I'll get to it as soon as un-retired life allows!

  VERY interesting, Matt. It agrees with similar tests done in Sweden a few years ago using a chase car & camera. One suggestion for more work for your project; I suspect most of the turbulence and resulting thick boundary layer along the sides comes from the frontmost section of our rain gutters, which are only pop-rivited on. Could I talk you into re-running this particular test with the driver's gutter removed or at least duct-taped smooth? I could be way-wrong, but maybe a simple front of the gutter removal would make the smaller scoops efective? Al Bloomberg's record-setting Bonneville pushbutton had its gutters removed but were never really tested.
  THanks so much for your work- J DeRyke
