Hello,
Seems you guys talk about higher speeds than I see. At 2700rpm / 7600 DA, I was seeing 159 TAS. Does that seem slow to you? I have an O320 with an after market Injector - The previous owner said 160hp. And a Catto Prop. Not sure which pitch but Catto website says they'll all do the same top speed just at different RPM. This occurred at 1150 pounds.

What are your top speeds? Does it make sense I'm only getting 159?

Thanks

Ray

What is your INDICATED airspeed at 7500 feet? How are you converting to TAS?

142 IAS. Dynon is doing the heavy lifting for me there. This picture isn't exactly 2700 and 159 TAS but that was what it flattened out at over a few minutes.
