OK, so finally finished my wheelpants and dialing in the prop.
RV-9A, Titan IO-340 180hp, WW GA-200L prop
75% 2650rpm 9.2gph 164kts TAS 8500' (189mph)
65% 2540rpm 7.9gph 154kts TAS 8500' (177mph)
56% 2440rpm 6.8gph 149kts TAS 8500' (171mph)
50% 2400rpm 6.0gph 146kts TAS 8500' (168mph)
I was expecting a bit more at the top end; I was at full throttle, peak EGT.
Van's website numbers for 160hp list 186mph at 75%, I figured the extra 20hp would buy me 10mph?
