Al, very nice install job and thx for the pictures. Should work very
well. What
are you going to do to anchor it within the wing?

Thanks; and your welcome.  The inside end was actually molded to fit a
mockup with space for support pads of Kool-Mat.  Also at the bottom and top
corners of the outside end are spaced with Kool-Mat so the rad nowhere
touches the fiberglass, and the is a thin flow path around to outside to
keep the surfaces cooler.  It is further supported by the cover plate as
shown in the attached pic. (Gasket material between plate and radiator is
not shown).

Don't have a picture of the inlet scoop yet, but it extends into the air
stream only about 5/8" out the bottom to minimize drag, and is a precise
airfoil shape going into the scoop to accelerate to air up and in.

The shape of the ducting is certainly a compromise because the space
constraints here are quite severe, but I tried to match my analysis as
closely as possible.  The exit air faring area is about 1.8 times the inlet
area to accelerate the air back into the airstream.  I'm expecting (hoping)
that the airflow through there will be a fairly low drag situation.  Inlet
or outlet flaps were just going to be too much hassle.
