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.
