Joe,
The cooling air exit needs to be pointed aft like a jet engine exhaust.
Blast to the rear, not down.
Sorry if my semantics have created any confusion.

Pete,
The idea for the larger opening size is to accommodate the increased air
volume due to engine heating. However, the exit methodology is particularly
critical to the overall efficiency for getting the cooling air overboard and
back into the airstream. Simply cutting a big hole in the bottom

The other alternative would be to open up the openings underneath and use the
already high pressure air being forced under the cowling to assist in being
drawn into the cowling, and install vents near the firewall baffles, closing
off the openings in the front behind the prop. If you look at the
