Mike,
This is for a canard aircraft where the P-51 style scoop is the ‘Out
of the box’ solution but for an air-cooled engine vs. a water cooled
solution.
Ed,
I sent the North American Radiator page. It’s a little
big. It’s pretty large so if you have any trouble, let me know and I’ll
post it on a web location.
Thanks,
T Mann

Cant help
you there Ed, but I can tell you this. The inlet and exit on Strega, the
unlimited Reno racer, which is a highly modified P-51, is even smaller than
stock. Strega probably produces two to three times the HP of a stock P-51. Many
years ago when first contemplating the 13B install I walked around the Reno
pits with a tape measure and took a bunch of notes (which I've long since
lost).
Another
interesting tidbit about Strega is the inlet eliminates the boundary layer
splitter found on the stock Mustang which is supposed to be so necessary.
Having said
all that, I still think its easier/better to keep the cooling system under the
cowl in most cases. More likely to come up with something that works out of the
box, and I'm sure it works better during extended ground runs/taxi, something
even stock Mustangs have a problem with.

Boy, they really skinny down the inlets and exits on that P 51
duct. If you ever come up with the dimensions of the radiator I would like
to know them. I’d like to try and calculate some of the airflow
parameters in the duct while at 400 + Mph to see how much power it would
theoretically dissipate based on air flow alone..

I’m still on my quest for information to improve on
my design of my P-51 scoop. I did acquire an accurate drawing that is a true
scale rendering of the scoop and the diffuser. I figured I’d better share
it. It’s a little difficult to find.
I apologize for the quality of the drawing. It’s a print
from digital rendering from a microfiche of the original blueprints from North
American. It’s enough for me to transfer to CAD and then scale to my
application. Interesting stuff.
I scaled it down but it’s too big to attach so please use
