As part of the recent condition inspection of my RV-8A, the Whirlwind RV200 prop was sent back to Ohio for the 6 year tear down inspection. The plane performed the same as before the condition inspection for roughly 2-3 hours. On a recent local flight I noticed that the plane did not accelerate as normal, sluggish, on the take off roll and at 1,800 feet, 27 inches of manifold pressure, and 2500 RPM the plane was only indication 130 Knots. At this altitude and RPM it would normally take 19 inches of manifold pressure to get 135 Knots. In the pattern the plane was much slower for any combination of manifold pressure and RPM when compared to all previous flights. The prop does cycle properly and responds in flight as it is adjusted. Could have something happened with the prop to result in these performance changes? It was the only thing changed during the condition inspection.
