Where do you flying guys set the manifold pressure
when on approach in the pattern? I would assume somewhere between 15 to
20 inches?? What does that give you in RPM? I assume you are
approaching at about 90 knots?

Most of my flying with the Velocity 20B is between about
16-21” MAP. That may be equivalent to about 17-23 on other installations
as my MAP pickup is near the ports. On downwind I’m probably somewhere
around 16”; haven’t paid attention (that’s about 4000 rpm and
100kts, and on final maybe 13” or less. With this slippery airplane
I’d say at some point on an approach the throttle is closed and MAP is 9-10”,
and the prop is my air-brake.
