If the prop load was maxed out, the rpm
would not increase, but the MAP could go up. It sounds, tho, like this
might not have been the case since Earnest felt the prop was not pulling.

Why
wouldn't you expect the map to go up when you have a blower pressurizing it?
Well, if the MAP was
actually higher, the engine would be making more power. It wasn't because
the rpm in both cases was the same. That's why I'm confused by the graph
if it really is MAP ( Manifold Absolute Pressure) you are measuring.
