Read on another forum that appears to be dedicated to chainsaw performance about a fellow testing his cutting times when using different fuels/chains. He did it all freehand, or simply timing his cuts. This did not seem very scientific at all as there would be so many variables injected into the tests. Scientific = best.
I believe the best way to test a chain would be to build a fixture that would only allow for vertical movement of the saw. The saw would be fixed to the fixture, and using a recording tach, the time from rpm drop to rpm increase would be the time-in-cut. Since human hands wouldn't be involved, this would really show which chain, or which pitch chain/sharpening method would work the best. All that would be required is the log diameter closely measured so each cut would be the same as the last, and the saw would have to be allowed to cool for a given period of time. But I haven't heard of anyone using something like this. Why?
And...
Why doesn't anyone dyno their saws really wring out what fuel and mixture would give them the best results?
