Make that a <G>. I have a standard
Velocity with a Lyc LIO-360 at 205 hp (allegedly) and I can make about
140 - 145 kts. Maybe 150 or 155 so with wheel pants. Mine is
not an ideal or optimized Velocity, and there's a lot of weight in the
front seat which is important on canards, but I would regard 200 honest
hp a good place to start.
I would go with a Renesis. O-540 power right out the gate, and
always the option of turbo. Who was it said brand new renesis
costs like used rebuilt 20B?
That would be my choice .... Jim S.

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

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.John
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

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 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. Rino
