What are the times on those?

It was at the end of the video, but my editing skills suck so I couldn’t get it to stay on the screen very long.

I really appreciate the extra effort of putting this in the video, as supposed to no numbers or scrolling through a video to find them.

Sorry, didn't hang in to finish the last saw.

The 572/361/390 seem on par

7 ish for the 572, just over 7 for the 361 probably the same 7 in the 390, but more tq

I agree with you, I think the dyno numbers seem to make sense in conjunction with the video results.

I actually got the saw because I run a short bar Yes, my wood is small

Should have let them purely self feed for even better accuracy. That's what I'm trying to do lately.

Tall freakin order IMHO.

 

[RI Chevy]

Just need consistency in your cuts.

It's about reducing variables. taking one hand and a bunch of leaning out of the equation leaves only one hand, wood conditions and powerhead weight as the leftover variables. See here how my one hand is floating around the handle bar only as a safety measure.


Does that look so hard?

See here how my one hand is floating around the handle bar only as a safety measure and to catch the saw at the end of the cut.

When I run saws I run them where they want to be in the wood. After you run enough saws over the years you can pick one up and tell how it wants to be ran in the cut. Maybe that’s wrong idk but it works for me lol. The chain, sprocket and wood species is also a variable. But really the dyno eliminates most of those variables. I was just stating that what I saw with the 361 when I had it here in the wood made sense with what Joe saw on the dyno. Which is nice to see.

Ive noticed my wood gets smaller the older I get.

Prolly for the best, keeps us outta trouble...

Your hand should be firmly gripping that top handle with your thumb wrapped around it. You're asking for trouble. Just some advice from a dumb guy.

How many cuts before the self feeding slows down?
Then file and start over? What if there are 5 saws to test. Chain is compromised after the first two saws. Hundredths lead to tenths, tenths lead to seconds.

Wood is for sawyers. Dynos is for horses. dis da dyno thread...

Slowest saw is 7.1hp ~

Fastest saw is 38% quicker

38% more than 7.1 would be 2.69 ~

9.8 hp ~ roughly... if we think the correlation is 1:1

Hp gain vs cut speed gain.

Im guessing you're referring to letting huskies self feed and stihl some mild pressure in the cut

Maybe @crowslayer17 should send that 6100 in for a run and see how she does...

I've been thinking about it. I need the address, I can't even keep up with this thread and it is awesome.

Depends on the model more than the brand. The 394 needed a lot more pressure than the 064 and 660 in the video.
