Perry,

You might take a look at CP47, page 11, (Canard Pusher, EZ newsletter).  This
page shows work that Dick Rutan did for the Voyager, regarding oil cooling.

It shows several I would say "fences" (they call them scoops), configurations
ahead of the oil cooler, on the low pressure side.  Delta P's ran from 1.8"
H20 to 3.8" H2O, depending on placement.

Sorry I don't have a scanner.  Perhaps you can scan that page and get Paul's
input.

Joe:

Thanks for the tip.  Some people at Arlington last summer recommended
something similar. My exit louvres emulate this first picture of a 3rd
gen (red).  But I think the little deflector in front like in the second
picture (black) might help, or the full reverse scoop like Voyager. I
can scan the CP at work on Monday.
