Another chainsaw dyno...

We're you part of the race with Heath and the 1201?

Yup

 

[Red97]

Yup

Yep that one.

Prolly real similar to the cs1200 power/graph I posted.

They sound like dogs when I've seen them run. Big, heavy, slow. But I'm sure a few of you guys here could give one a boot in the arse and wake it up.
They pull long bars though. More torque than HP. LOL

I think many have been tuned incorrectly over the years, not tuned to 11,000rpm governor disconnected as per full service manual.

Peak power is 7000rpm, where it should be cutting, so if it sounds like a complete turd it ain’t right.

Good to know. I have yet to see one of any sort that ran worth a crap. Always seemed under achievers. I know they can ravage a rain forest (eventually).

Even tuned right they’re turds. But cool turds.
Dual 661’s were 3x faster (and 3x lighter) than dual 090’s milling red elm in PA

Where's the FUN FACTOR though? Come on now...lol

Well of course they are turds to a 661, they are a 1960s Model saw.

Well I did say cool turds.

 

[rogue60]

Mine runs ok that's some extremely hard wood.

 

[RI Chevy]

Nice.
Tighten your chain up a bit. Lol
I hear that White Knuckle Guy can really wake them up! [emoji16]
Were you running .404?

 

[Wolverine]

So moral of the story is... there IS a replacement for displacement. It’s called technology.

 

[RI Chevy]

LMAO...YES...[emoji2957][emoji28][emoji1787]

Also called porting...

Chain was fine for what I was doing it's a hardnose bar the chain does that gets loose fast under stress just part of running a hardnose bar.

Who's White Knuckle Guy?

Yes .404 RS do they make other kinds of chain? lol

Oh you mean Tony yeah I'm not really in the ported saw seen stock with a good chain is fine for me occasionally I might attack one with a Dremal and I hate loud exhausts lol

 

[RI Chevy]

OK. Gotcha..[emoji106]

Or positive intake pressure

 

[MustangMike]

Well, Joe said he would send my saw back on Wed, and the postman just came and gave me a large box! Thanks Joe, I guess return shipping went much smoother than sending it out there! Did not open it yet, but box is undamaged.

It is nice to know my "hardwood noodler" is home again!

 

[ferris]

Yeah that would suck not a cheap saw now days seen one here sell for over 4k awhile ago was new I think from memory.
Mines stock no port work some say 9hp some say 12 or 13hp never really found the truth on what they are?

12 or 13 are SAE HP

 

[Red97]

Lots of activity in the 20cc class

Yet another lead change.
