Another chainsaw dyno...

[jacob j.]

I rationalize the total cost this way:

Mike - you don't have to rationalize anything. This is a chainsaw forum. Pretty much everything we do here would be considered ridiculous by normal people...

Eh, we’re the normal ones. Normal people are the crazy ones

Good troffs ^



I'm saving the last 35 pages here for this weekend.


Dis ting broke yet?...

Couple things to a dress, but no actual breakage. Taken a few good hits too.

This is one of my favorite threads ever! I have been watching from the beginning and it's pure enjoyment! It's amazing that some of the ported "work saws" are seeing upwards of 33-34 % gains from manufacturer numbers! The hybrids and strokers are crazy! Curious @Red97 do you have a list of all saws that you have run on the dyno or some kind of spread sheet, just a list with saws , hp and torque?

Thanks!

I know my saws are strong. I am just not up to the risk of sending my saws out through USPS and getting them back during these times when the mail has been put to the limits.
I'd love to test, but I'm not a gambling type of man. I work hard for my money. LOL
Sorry, just me.
I do admit, this is a cool thread. Good to see whats going on out there. [emoji106]
Keep up the good work Joe. Thanks for doing all of this.

Wouldn't a dyno have been cheaper, simpler, smaller with a friction brake or eddie current brake? Then rig up one of those simple cheap computers like Arduino or raspberry Pi for data recording/graphing.

Amazing thread btw.

I wonder if the irregular power curve up in the revs is a result of reed valve 'flutter' on the 6100.

A change in reed material or thickness might change the curve.

I always wanted to see how a different set of reeds would affect the 6100. I suspect the factory may have found a particularly strong running set of reeds, but the reeds could have been too fragile for commercial sales and it would reflect poorly on the 6100s reliability.

If I ever get one of those puppies, I'd go with a bigger carb and thinner reeds with probably a lower reed stop.

EDIT: Was the 'limiter jet' in the carburetor's low speed circuit enlarged?

I’ll chime in on this one. Lol. Yes I missed the carb in this saw. You have to or they won’t run right when ported.

Build one, eager to see your results.

The absorber is just 7" diameter 3" thick the a 16" arm

The stand/table is what takes up the room.

I didn't want all the trial/error in a complete custom setup/control. Wimped out and went with a store bought ready to run system. Just had to make a way to hook the saws up. Simple jackshaft, hooked to a saw chain.

I think your sand bagging a little, like most everyone else!

Nah. If it’s more than that I’m real surprised. I’m just guessing based off the other 66 that tree monkey sent in.

Afternoon John. How are the fibers?

 

[Redfin]

Bright and fast today. Sat not so much. Got a call for a mux failure at a radar sight. On site tech asked if I wanted to go up in the dome.

Hell yeah I do. Was cool to see it.

 

[Wilhelm]

Like for all the tested Dolmar saws!

Thank You very much.

 

[mdavlee]

Too much money to send, test and send back. Just sent a package to Denver, CO. Guy says he never got it. Cost me $300

How about a prepaid fedex or UPS label? I’d like to see that 66 and maybe Kevin’s non decomp on the dyno.

Your not thinking very positive...lol

Gotta get it out there AND back Mikey...lol

You can print them for both ways at once[emoji23]

you forget his wife has a lock on his wallet
I have 3 in the mail now

I'm just a poor man who has too much to lose if the saws get "lost ." I have way too much to lose monetarily.
If someone wants to foot the bill both ways to get a saw to and from I'll consider...
