Is the rpm limit because of diameter (tip speed) or = a structural blade limitation ?..............=

The prop is adjustable, it is hydraulically control= led.  I current have it set to the fine pitch setting.

This is not full throttle, I have to stop at 6000 RPMs do to the 2150 = RPM limit on my prop. I am using a VARI PROP, it is great so far. &nbs= p; I have plenty of throttle, just prop limited.

23.3 is just about ex= actly what would be expected.

Perhaps the throttle is not opening al= l the way?  You would have to have a pretty convoluted intake to lose = 3" of pressure in it.

My static MAP before starting the engine was 23.3
