Did more testing of the chains that I still have minus TRX's chain, that I still did not have a .063 84DL bar to run it on, but I will and still have the cants in the stand, so those #'s will be coming some time later in the week..
The test mule was a ported 7900 with an 8 pin and 24" bar.. AWOL and Redhorse ran the stop watches, and we made mental notes and discussed some things about each chain after the runs were made... We had some "ah hah" moments, and some head scratching moments..
Here's the chart. I'll add my thoughts and details I noticed about each chain later. We used 2 different wood types and sizes.
The nasty Hackberry was sawn into an octagon about 14" and the pine was sawn square. "much more material in the pine cant."

Awol and I inspected the chains to see if there was any "extra" work done to them, like chassis work and thinning inside and under the cutters, or stoning / milling the outside.. If there was, we dubbed it a race ready chain.
Anything that was just filed, we dubbed a work chain.
Redhorse got to inspect the chains and scratch his head too...
I'm sure he and awol will add some observations to the discussion later too..

Try to focus on the pine #'s...
We came to the conclusion that Hackberry chunk just sucked... Would have been a good dollar race log!!!
Though I noticed the chains with the lower rakers made up ground or passed the smooth, high raker chains, with more power..
 
Oh, and for what it's worth, I liked the stock RS offering better than the stock RSL!!!
It was smoother!!
Moparmyway's chain found a saw it really liked in the 7900.. Pulled hard, but was smooth, and skip to boot.. It had about 20-25 degree top plate FWIW... Was just right for the Hackberry, just couldn't remove the gobs of pine fast enough.. Teeth were a little short..
Just some observations...
 
were the chips off the different chains all close to the same size ? did more raker help in this test ?Is the chain i sent you for the 36 inch bar still sharp ?If only 15 inches is being used does a longer bar slow them down all that much ? am curious how that first chain was compared to the one i messed with the rakers on

Hmmm... Let's talk chips...
There weren't any chips really from the Hackberry... I think they were breaking up before discharge. Very stringy, but most of the chains were doing a good job of shearing off the fibers... The end of the log looked pretty good except we noticed some fuzz from the stock RS.
The pine showed some nice chips.. But the longest peels came NOT, from the fastest chain... But it did have good chips.
Awol and Redhorse can chime in any time with their observations.
 
Yes, the fastest chain in each species did have tunneling/ thinning done, whether from the inside or outside. The second fastest chains in each species were not thinned at all though!
