Running my Cherokee 6 at LOP at ~7500 feet. I was doing laminar flow testing on the wing, so wanted to get near best climb speed (110-115mph). Dirty oil was run along the front of the wing, and where it pooled where areas of detachment.
Specs as follows:
1970 PA32-260, over FWA
Turbo not engaged
MP 19 inches (throttle plate pulled back about 1/2" to mix air better)
RPM 2300
Fuel flow: ~9.9 gal/hr
EGT diffs 35-40F
Indicated airspeed: 115mph
OAT: 15C
True airspeed: ~131mph
Doesn't you ALT show 7400 feet at 0:24?
