Dan, Something occurred to me as I was looking at your cowl pictures. You stated that the outbd sides of the slot-scoop are going to provide cooling air to the bottom of the engine. If you do that, won't that cause air to stagnate inside the cowling and overheat the engine? The cooling air from the upper openings behind the prop is high pressure. By allowing high pressure air to the bottom of the engine, haven't you effectively shut off the flow of air? To achieve proper cooling, you'll need high pressure / volume air at the top / front of the engine flowing into a low pressure area below and aft of the engine. In other words, you're needing a pressure differential to achive flow. I think that maybe you should block off the lower side openings and use the scoop only for carb air, or at least be prepared to do that during flight testing.
