Another chainsaw dyno...

[qurotro]

That.. Look like a clamshell saw made by Efco in china.

Plastic case half clam.

Like a husqvarna 350.

 

[Red97]

Purdy clean 044.

 

[Canadian farm boy]

Now that’s an impressive improvement. 2hp increase and moved the peak out almost 2k rpms. Very nicely done Mr Joe. I’d happily run that saw any day.

Thank you.

It needs more muffler, and a maxflo. I'm still happy with the way it turned out.

I love dyno’s. That 044 sure looks like a power house.

I wish I could test that saw in wood.

I’ve not met the man in person.

Just what I see on this forum.

Same.

 

[Fruecrue]

He’s the same in person.
What we can’t see here is the grin he’s wearing when he’s trying to get a rise out of people.

Closed port 365

Baseline runs were gasket delete and slight muffler mod.

Stock carb, nothing crazy. Very happy with these gains.


And ported 365 vs ported 372

That's pretty good for a stockish and ported 65 cc saw

To my surprise the 372 is only that much stronger that the 365. I should dig up that used 365 jug in my junk pile.

 

[TreeLife]

The curve on the 365 looks more work friendly if I'm reading that graph correctly

Some 50cc gains from a 501p

Lots of grinding, but these are getting better.
