I'm just curious what others are seeing with their Sensenich prop/RPMs at various power settings and altitudes? I have an RV-4 with an O-360, dual P Mags, and the standard Van's 85" prop.
Since adding my wheelpants and fairings to my new RV-4, I am having a lot of occurrences of hitting the 2700 RPM limit unless I pull the power back quite a bit (sometimes I have to pull it back to about 1/3 of the way). This is happening up high as well (7,500+ in altitude) - not just lower altitudes where the engine can develop full power.
At the beginning of my takeoff roll I'm showing just about 2180-2200 RPMs, increasing as I pick up speed. The numbers are pretty good - 2,200 FPM climb, and just over 200 MPH TAS. It seems like I could go a lot faster if I had more prop bite (2 - 3 inches more pitch) and could therefore be at full throttle. Anyone else run into this?
Thanks,
Rick
