I've been playing with a 346 lately,very sporty little saw.

A carb and boot upgrade is definitely going to happen.

My 340 is Out For Delivery. I'm anxious to see how it fairs on the dyno.

Brad I should be able to get you graphs for this saw tonight. I'm going to try to get them all out to the various saw owners before the night is up.

Eric, I never got to see / compare the graphs for my saws... though I did see Brads. I was too focused on getting the runs on film. If its possible, put 7 "best" averaged runs together on the same graph, color coded?

PB w/ muff mod
saw #1,3,4,5

PB w/ stock muff

ya....7 ... would be awesome to see such a graph.

Hey Matt -- I will make an attempt after I get all of the graphs to each saw builder (including you!) as I know they are patiently waiting for their data.

What it makes it tough is the number of points collected for each varies and the RPM scales at the bottom vary greatly.
I do have the time stamps every 100 ms for each -- so if you don't mind the time being at the bottom of the graph and the RPMs as additional lines that might work... it'll be so busy though I don't think they'd be readable.

I'm not sure what's best to do, but certainly after all of the regular graphs are out I'll play around in excel to see if I can get what you are after.

On the list of things to do for the dyno as "features" is the ability to plot multiple runs on the same graph. It may require some fiddling with each RPM sample to match them up... Someday if we have a dyno where the computer controls the RPM (don't get me wrong Bill does an excellent job at getting a nice RPM curve with the hand controlled brake!) we can more easily "line up" the various lines on a common RPM increment.

See ya!

Thanks for Sharing Brad, and thanks for the work Matt.

Erik, you can post the graphs any way you like, but I think the most information to be gleaned from the challenge is to be able to overlay the graphs best as possible. ie, somehow come up with a "best example" interpolated curve for each 350 and then overlay them all on the same graph with different colors.... you can do it!

This was the strongest saw we dynoed. And the strongest saw I've ever run! Thanks for sending it out Jason!

Deets saw didn't make it for the gtg, so here is a peek at it with Jason's saw for comparison

That's a couple strong saws.

Every ported 064 I've ever seen or heard about has been a beast. I'm surprised it they don't get the love like the rest of the 4 and 6 series Stihls.

You ain't kidding Jason! They are beasts for sure!

at least you are wearing a shirt in this one

Those saws do sound very robust!
I just noticed that it looks like a chain snapped on one of the saws.
And it seems like when you do a certain cut, letting tge tip go way down toward the ground, when leveling back off, it makes the saws bind. You're probably leaning on it really heavy.
Other than that, those 2 saws are awesome. I want one. Lol

I've got my chaps on...
That was for Al! Lol

It threw the chain at the end of the cut. Yes I was trying to load the saws but they weren't clearing chips enough for the pressure I gave it...
