Took my bird out today for a local flight, it was between 0 and -10 F. Hadn't received the oil cooler shutter yet, so I taped most of it off. Should have blocked it completely as the highest oil temp I saw was only 178 F.
I couldn't lean the engine nearly as much, only down to 8.8 GPH at 8500, but the true airspeed was really up there, 182 knots, verified by GPS groundspeed. This at full throttle and 2500 RPM.
I also noticed the increased lift at during the flair, which lasted about twice as long.
It was a beautiful sunny day, with smooth, thick air; at one point I throttled back to 135 knots and flew above the Missouri river at 500 AGL, following each curve and curl of this river that is just really a baby at this point. Hard to believe it ends up draining one-sixth of the continental US before it joins the Mississippi river just north of St. Louis Missouri. I flew over the dam where hydroguy2 works, but much higher than 500 AGL, that's a tight little spot there.
