Last cylinder to go LOP

How far LOP do you take the last cylinder to go LOP?

It depends on how much power you are going to run. On my Turbo 260c I figure Lop fuel flow determines power, so with 8.5:1 compression ff*14.89/engine max horse power determines percent power. So with those calculation 60% power I figure I should be approx 20 degrees on lean side of peak, and at 85% power I should be approx 90 degrees lean side of peak.

steve,
i would think that depends on u'r gami spread?
The question in my mind would be not the last one to go LOP, but how far has the first one gone now?
The leanest one might be unhappy and getting too quiet?
Just my thoughts....
I've also tried to go LOP at high altitudes, teens, summer, but found the air too thin to cool my CHT's, so i pulled the MP 1"
and went 75 ROP, and got similar speeds, FF, but my CHT's were better...
otherwise to answer u'r question, no idea????
