Here's an interesting question.

 

Considering the exhaust heat of the rotary is so much higher than a

Lycoming, if doing a side-by-side comparison of the two with equal fuel

burn rates, wouldn't the Lycoming have more engine heat to remove from

under the cowl than the rotary?

 

The short answer is that it is not a very interesting questionJ.  Too many variables, and not a real important difference.
