C. Air enters a sealed duct, goes through the rad and exits directly
outside. Perry and Ted Nickel. Works great. Perry and Ted both with
very small rads and are not complaining about water
cooling. Perry still
has an oil cooling problem we think but we are not sure.

Here is a picture of Ted's set up with cowl flap.

Paul, I understand an fully intend to use a sealed
inlet and some sort of cowl flap. It may be the blow out arrangement 
with "gills" or the exit duct arangement
with a exit flap hinging into the airstream on the sides.
 My plan is to build a test fixture firewall and cowl to
test with. It is sort of costly but like your home dyno
it will allow full power testing for at least short periods.
 The plane in the air will have higher airflow due to
forward speed. If I can keep it cool on the ground I
will have made a good start.
 How big is Ted's radiator? It looks like a nice arrange-
ment. Thanks for all the vital info, Bill Jepson

I don't recall the exact size.
Here is a test rig I used to verify K&M findings.
I guess this was before your time.
