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.
