My spinner is 16" in diameter and the duct opening is 16x5 inches for a
frontal area of 80 square inches. The radiator is 17x18 x 2 inches
thick. I was thinking that the opening of the duct ought to be a little
smaller, say, 4x16 for an opeing of 64 square inches. that would be 20%
of the frontal area of  of the radiator/oil cooler.Anyone have any input?

20% should work fine Brian. You might contact Will James.
He may have a cowl for you with that type of scoop that will fit.

You should do this now before you get too far along.
