Another chainsaw dyno...

[huskyboy]

I spend most of my time between 8500 and 11,000rpm when felling timber or cutting firewood. I left the fast tach on the saw for a while and observed (which is quite annoying because it is in the way lol). As soon as the chain gets a little dull in the real world, it cuts better with pressure at a lower rpm than a higher rpm. This is where peaky builds usually fall on there face, they are more fussy with chain sharpness and aggressiveness. I don’t make a habit out of cutting with dull chains... but it’s just a reality when working out there in the woods and ya gotta finish a few cuts with a slightly subpar chain before you take a filing break. Rocked chain or dulled from dirt I stop and sharpen right away though.

Lol. That wood would be my neighbor’s dying and rotten oak tree

There ya go! You're still young. When it comes to saws and women dont be picky. Try em all. Little ones big ones medium ones... you get the idea

Well I will be buying an Echo 501P for Father’s Day. Should be the perfect saw for my size wood

 

[Bigmac]

An 044 would be considered overkill for the size wood that I cut, usually around 14” diameter

You need to find reasons to find larger wood!

Working in a tree service once I turn 16. And I can always hear what sounds like an 044 in at least one tree service

 

[NPKenny]

This thread is full of wisdom.

The dyno chart on the 044 tells me that that is about the only saw to have as a 16 year old. It certainly won't care if you are only cutting 14" trees.

Thanks for all that info, you are confirming why I have kept my 10 mm 044 since Dec 92. Along the way it has embarrassed several 046/460s and 066/660s, but to be quite honest I am usually running the "better chain".

My 044 does not have any port work, but with a BGD and TA, steel screen filter ant dp cover, I'll bet it is real close to the one you have there.

Great stuff … THANKS!

SN 129 + change. I think around 93 or 94. Some of the early 12 mm saws (especially the slant fin jugs) run very well, as do some 440s, they just don't seem to be as "consistently strong".

I had a 440 that ran just as strong as another 10 mm 044 that I had, but this 10 mm (the one I had since new) is just a little stronger than both of them were. The other one was an early 10 mm Black Lever, with the 4 mm recoil bolts.

 

[huskyboy]

With this 10mm 044 talk also comes with a question. When did they discontinue the 10mm 044 and replace it with a 12mm?

Weak cranks. Guys were pulling on pinched saws and breaking the crank apparently. The 12mm crank is stronger and has a larger wrist pin bearing hence the “12mm” designation.

 

[MustangMike]

Some broke, and some seemed to go through Heck and back and still run. My tree guy is still running one, and his guys are not easy on saws.

So, who is gonna send some saws for Joe to dyno?

 

[Bigmac]

See this is where it gets fun... do you run a 8pin on that 395 and let it hog at 9k?

And a 7 on the 066 at 11k? Then what?

Can't wait till I get this stock 395 on the dyno.

That would be a cool test. 11k 7 pin is pretty equal to 8 pin at 9.6k chain speed wise. It also depends on the operators style, a ham hands will love that 395, but it is ported too. Eventually when you test more saws you will have good baseline on several models.

 

[Terry Syd]

Some mods take a fair bit of time and effort to execute. It would be interesting to see if the time and effort of putting in 'fingers' or 'bridge ports' was justified.

After seeing the graphs. He wants the 066 ported.

Try and make thast one gain some.

Awesome! Will be fun to see the results

What did the 395 have done to it? Anything?

Sorry if I missed that. The 395 looks like it’s being choked for air. My bet is that the muffler needs to be modded badly.

As much as a Stihl guy I am, a 395 should walk all over an 066 in terms of overall power. In terms of weight and ergonomics, I’d take an 066 if I had to swing it all day. But for bucking big wood, the 395 really still is “The King”. Rarely seen a well done 066/660 beat any good 395 through big wood. The 066/660 are limited by their piston skirt width, and it seems that dual port saws (like the 394) always feel more brutal than the faster running quad port saws.

Just my $.02

I think the 661 shares the throne with the 395 ............. they can both be long bar monsters !

When I get my 661 built it is going to head over to Joe's place

Your $.02 are spot on.

The 395 drop HP so steeply... Doesn't make sense.
