Sounds reasonable to me Randy. You probably have the option of
either raising the RPM limit to 7000 or P port to get the 200 - 220 HP.
I'd opt for the former rather than the later for cost & time
reasons. You will still be cruising at 6000 or less when geared and
proped for the 7000 limit. If you do go for the P Port route, I'll be
very interested in the results. Be very careful about location & size
of the port though. This is virgin territory you will be tackling.

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
