Bob; The 40 sq. will not cool the engine. Ed and others are
using a 2 1/2 inch x 10 inch hole under the spinner for the oil cooler, as more
than half of the engine cooling is through oil, as I understand it. I'm
working on the oil cooler opening as well as the round holes to cool the
coolant. My exit is currently 61.8 sq. inches, so it appears that I need
to add some type of cowl flaps to exit more air.

inlets
That's good to know that you think around 40 square inches of air inlet
will cool your motor. I'm planning to run an underbelly air scoop to the
radiator that will have 51 sq. in. inlet. I had no idea if that would be
enough. but from what you guys are saying, in should be sufficient for my
20B.
