About a month ago my dad and I did timed cuts with full skip and full comp chains. All cuts were made with my Walkerized 372xp with 22" bar and chains. Cuts were all made with saw warm and chains sharp. Some in poplar, some in red oak. Didn't measure the log diameter, since it doesn't matter for this test. I would guess it to be in the 14" range. Also made some cuts with my cousins new 460mag and my walkerized 346xp. Here are the numbers. Enjoy.
W372xp 22" bar
poplar full skip 3.06/3.00/3.02 full comp 2.28/2.44/2.5
red oak full skip 7.8/8.0 full comp 6.52/6.7
white pine 3.6/3.7 bigger white pine 9.6/9.1/9.4
white pine 3.0/3.1 bigger white pine 6.2/6.1/6.3
bigger white pine 11.8/10.8/12.2
Interesting to see the numbers out of the 346 compared to the 460, considering the displacement difference.
We also ran comparisons between a stock 346 and my walkerized 346, and between a 16" bar with semi chisel and a 20" bar with full chisel, both safety chains, different cutters.
Here are those times.
Stock 346 16" semi
poplar 10/10.1 20" full 6.7/7.25
Walkerized 346 16" semi
poplar 7.25/7.28 20" full 5.3/5.9
Sorry about the length, but here are the numbers.
Sorry fellas, I screwed up with my terminology. The numbers for the 346xp are with semi-chisel and full chisel. Too much homemade wine.
