Tom,

As you know I was running a fully enclosed Taurus 52 on my Edge. The only air inlets were the stock "cheeks" in the cowl and the lower faux "scoop" that I opened up to permit air entry. Incoming air at the cheek inlets missed the engine completly and the lower scoop impacts the middle cylinder head directly. Exit area was met by opening up the raised half moon on the bottom of the cowl. There were no heating issues that I was able to note with the Taurus installation. Speaking of half moons and cowls, that would be something nice to incorporate into the Extra cowl. When opened up, the remaining lip for the raised area creates a nice low pressure zone.

As for the Sukhoi, it should have more than enough inlet area to meet the need of any single that would fully fit. As in anything else, exit area will be the critical item, and there should be no probloem providing that at the bottom of the cowl.
