The following are the figures for my old engine. I have not done the flight test with the new motor yet. The new engine seems to turn a little slower for the same fuel flow rate. This fall I will fly a new set of test and collect new performance data for the plane with the new engine.
-DA-----RPM----%Power*---GPH----TAS-MPH/Knts
3500----2450-----75------8.4------128/111
12,500--2750-----69------7.8------142/123
17,800--2500-----58------6.8------130/113
*% Power is based on the Lycoming Fuel Flow vs Power Tables for an 0-320-E2D at best power leaning. (The SportHawk is not equipped with a manifold pressure gage.)
