Doug, What is the engine turning at WOT..170 kts at 8000 DA?
I did this during my Phase 1 testing back in mid-2016, so the memory's a little fuzzy, but I think it was in the 2850-rpm range. I'm uncomfortable spinning the engine that high for any length of time, but I just wanted to "see what she'd do." Highest TAS on the way back from OSH was 161 kts at about 2700 rpm.

I'm extremely happy with the mix of economy/speed the -9 delivers.

The prop itself has a redline of 3200 rpm.

I have had two different engines on my -9, both with Catto two bladed props.

There is nothing else out there that combines the smoothness and performance of the Catto.

My first engine was a 135 hp O-290D2 and I now fly behind an O-360.

My numbers donít compare to an O-320 other than I can go faster while burning more fuel.

75% power for me is right at 175 knots / 200 mph but my typical flight is in the 155 to 160 knot range burning 7 GPH.

Climb rates depend on OAT and GW but it is not uncommon to see 1600 FPM when heavy.
