BTW it is extremely important you think through the
ducting for the cooling system before you proceed.
Since as much heat goes out the cooling system as goes 
out the prop shaft in the form of HP on all internal combustion 
engines not just the rotary.
You will be dealing with 200  HP times 746 watts per HP or
about the equavalent of 124... 1200 watt room heaters.

It can be done but it takes planning. Think about where you are 
going to put the rads and how you are going to duct the air  both
in and out. This is the key to getting the performance you
expect with a 200 HP engine. rrheat.jpg
