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.
