Paul,  I have been trying to come to some finality on the radiator
plenum.   I reversed  your process and started out with physical
model
of poster paper and plywood and then as I encountered problems, tried
to work it out with cad.  Anyway,  here is what I have come up with.
Please take it into consideration with the cowl designs.

     The cowl should slope back from under the spinner to a point
5/8"
below the rear lower corner of the radiator header tank.  From there
the louvers take over and it will flat and horizontal back to the
firewall.  The flat bottom needs to be 14.5 inches wide to allow room
for the louvers.

The photo was taken before I put the extension on the plenum to get
it
out the front of the cowl. In the photo, the plywood represents the
radiator and the duct tape is the header tanks.  The plenum opening
is
48 sq in which expands to 71.5 sq. in.  before it enters the wedge
portion.   Jerry

     Don't need to do that. Keep a constant AREA duct up to the start
of the core.

Jerry,
Have you bought a spinner yet? I'm planning on a 16" spinner also,
maybe from a mustang II, and was wondering about the price. Your
radiator has the same dimensions and looks like your inlet duct is
similar to what I'm planning.

No,  I have not bought the spinner yet.  I think the Mustang 2 spinner
will be quite expensive.  If we could get a few guys together, we might
be able to get Brian Alley to build us some CF spinners.  His work is
beautiful.    I have not talked to him about this and have no idea if
he would do it or the price.   Jerry
