Another chainsaw dyno...

[Red97]

ever had a diesel chainsaw on the dyno?

Nope lol

 

[Stump Shot]

Nope lol

That why it's called a dy-no and not a dy-yes?

MustangMike: likely the engine powering this thread is out of mixed gas.

unless someone straight gassed the thread

Here is the graph for an 064 I recently acquired from Shaun:

Nice gains! That s/b a real nice performer!

I think it will make chips fly.

What bore? Looks stronger than the stock bore Tree Monkey 064 I had.

I believe it is a stock bore.

My story is even though Joe is a friend and I have several saws I'd love to have on the dyno. It just isn't in the cards. So other than some ball busting and banter...... I've got zilch to contribute

I wonder how it would stack up against a ported 395? What's a Shaun 395 look like on a dyno?

Depends on who ported the 395 and what the goals were for the build. Shaun has videos posted of this 064 along with several other 90cc saws. Probably can’t draw conclusions from it due to varying log size and chain condition, etc, but the 064 cut at around 41 seconds his 394 at 37 and a 395 at 38 & change.

I won’t believe those numbers. But u can see the gains and the change in the curves.

No? Care to explain why not?

 

[MustangMike]

I believe the #s! I've seen TM 066s produce similar gains, and I've seen them run in wood!

I think what is meant is that every dyno is going to produce individual results based on who built it. So theoretically the numbers are subjective to that machine but not universal.
Joe's should be close to factory correct though.

I would trust Joe’s rig to as reliable as what the OEM uses. I think it is hard for some people to believe how much gains can be had. Also, as has been said many times before, peak HP while cool to look at, isn’t as important imo as the area under the torque curve.

It was a very stout "stock" 064 Joe put as the comparison graph. Built from NOS hand picked parts as well as it was muffler modded.

The numbers don't really mean all that much anyway. The curves do tell the tale.

But the numbers can be used against most any others posted in this thread. As they are all taken from the same machine.

Any updates to the dyno that could bump the numbers up a little?
