Today, I was just tooling around at 2900. Wide open rpm was hovering between 3350 and 3400 but I did not stay there long enough to get the speed up. I did not want to push the engine just yet after doing all that work on it. I guess I am slowly building my faith back up. Here are the specs I recorded on my voice recorder while I was flying level at 6000'. Altitude: 6000' Altimeter: 30.06 Oil Temp 195 RPM: 2900 Exhaust temp: 1250 Oil PSI: 35 CHT: 280 Indicated MPH: 125
