Lean of Peak operation

[JeffAxel]

Herb, 50LOP was where I ran the P Skymaster and it worked well. If I went leaner, the engines would start to miss, especially the rear one. If I went richer, I would get into temp issues (CHT and TIT) until I was quite a bit rich of peak, like 150ROP. If I had that plane now, I would try running it at 2450RPM, top of the green MP and 50 LOP. This might get me more speed. I was running at 60-65% power the way I was flying it. I took the APS course after I sold the P337, and would fly it a little different today. In my P210 I run 50LOP, but at higher power settings, so I really don't loose any speed, just go the same speed on 3gph less fuel. The TSIO 360 will run smoothly LOP if set up properly.
