This is the first time I've flown at WOT at altitude. The first time i was going over 2700RPM and was unsure about staying over for a little bit of time. This time i wanted to measure top speed so I stayed at WOT long enough to do that.
So at 2750 RPM, 21.4 MP, 73% power, 9.7GPH, 138 IAS, 162 TAS, 8670 DALT
When I compare this to Vans web site 75% power and 8,000 solo weight they state 187MPH or 162.5 KT. This matches up pretty well and I'm happy with that.
So the questions from a newbie here is... If I'm at full throttle producing 73% power, I presume with a fixed pitch prop there is no more in the tank so to speak. This is going to be my maximum speed. So is the only way to get to Van's top speed number with a constant speed propeller?
This is with an O-320 carburetor running one Mag and one EFII ignition. The prop is a 3-blade Catto 67x70 carbon composite.
