Al,
The SJ cowl is the one pictured in Dennis
H’s. posts. No cheeks, just a large scoop underneath the prop.

Al,
My plan was to pull from
the radiator scoop of the Sam james rotary cowl. Do you think this area
would be pressurized sufficiently at high speeds? Any significant effect
on radiator performance?

Bryan;
I know not of the Sam James cowl, or the
diffuser shape, so I can’t be of any help. I’d say the amount
of induction air is a small fraction of the cooling flow required.
