I guess we are trying to find the edge of the envelope. Charlie Airesman is using a small rad and a NACA duct with an augmenter and is doing over 200 mph with a 4 to 5g/h fuel burn. On the pusher, we can optimize the duct length. The augmenter will be tricky with the rotary. Ed provided some btu numbers to start with. Thanks

Isn't the conventional wisdom 3 cuin/hp? Al Wick's Subaru is about 2.5 but his
Soob doesn't have the cooling requirements of a rotary and I believe he has a
really nice (efficient - good recovery) plenum. I would think 3 minimum unless
you have really good ducting and plenum.
Just a theory ... Jim S.
