Gentlemen,
   I am reaching the point of purchasing an engine and trying to make a few decisions on what I want/need. What I have is a single seat biplane, what I need is 200/220 hp. Maximum airframe speed is 180 mph. I would like to use a n/a Renesis engine, p-ported if needed, turning at 6000 rpm using the 2.85 PSRU. I like the 6000 rpm as it is easy on the engine. I like the 2.85 because the prop turns in the "correct" direction. Using the slower turning "monster" prop as has been discussed here appeals to me especially if it increases climb rate. Is this HP realistic with this setup?  If this setup is not the best for what I need then what is? I am not an "engine man" so my decisions will be based on the experience of others.
Thank you for your advice,
Randy
