Wahoo,
another Velocity Builder. I am building a standard (with the standard
wing). I am using a two rotor, just not sure if standard 13b with standard
porting (for approx 200 hp) or a Renesis. The standard
Velocity can actually use a 160 hp which is a standard non ported 13b (or a Lyc
320) and still push it along at about 167 kts.....well according to the sales
literature <g>).
I was
seriously thinking the three rotor 20b when I first started my research, but
decided against the extra weight, scarcity, cost and complexity. I have
been constantly told the 13b should be able to be ported to 190 to 200 hp
without any real issue. Even though the turbo will add some complexity it should
give you the power you want.

Slade is using a 13b turbo in his Cozy and should be flying any day now....Right
John? He as a great website (with a lousy URL that I can't remember) but you can
link there from my builders site under the engine page)
Please
keep me/us posted as I am very interested in what you decide and how you do
it.
All
the best,
Chris

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.

I would go for the Renesis, the RX8 engine if I
was starting today.
It is much lighter for the same or better HP
than a 13b with turbo like I presently have.
