I am still on the fence, but would like to decide what engine to use.  I am building a Large wing Velocity, not the XL.  One of the original designers of that version of the plane recommends that an  io-540 250 horse would be the ideal engine.  Now I was thinking of either a 2 rotor that would be turboed to 200+ hp at sl not at 10K or a NA 3 rotor.

I would like to get a consensus of the better way to go?  Suggestions?  If I have to, I could probably hang the exhaust out the cowl, or modify the cowl so as to get some airflow over the exhaust to help cool it.

Bob, the turbo puts the exhaust exactly where you want it, acts as a very good muffler and you harvest the hot gasses for more power. I vote for13B Turbo.
