[DeTomaso] rain gutter aero

[JDeRyke at aol.com]

No- the tufts showed a boundary layer close to the body.... but if I 
remember rightly, not up at the windows. My experiment a decade ago with 
evaporative cooling on a damp finger stuck out approx. the back-middle of the window 
showed the boundary layer right in front of the left gill seems to be about 
4" thick. And thats the area I thought most likely affected by turbulence 
off the section of rain gutter on the front pillar.
I could be wrong but that seems to square with small scoops not 'scooping' 
any air at all, and wider elephant-ear scoops only working above around 150 
mph. Aero is interesting and very unpredictable at the same time. Cheers- J
