Roof plug 16.
Typical !! Tried several different side vents, and settled on the original
NACA air vents, i originally used in previous roof.
"Basically a NACA scoop is a recessed vent that aerodynamically draws air into it from the surface boundary layer air stream with very little penalty of drag."
http://en.wikipedia.org/wiki/NACA_duct
The rear section , as can be seen, has been removed , to allow for a drop. I have actually today, slightly widened this removed section.
Tomorrow, i plan to cut two NACA ducts, and use one half of each, to blend sides in. The reason for cutting two ducts, is that i originally made them as left and right, so not truly symmetrical.
