Snellerized MS461 on the dyno

[chadihman]

Hey do you have a picture of the saw on the dyno I'd love to see it?

This an MS 660 on the dyno taken a while back less the electronic testing equipment. I also added an electric fan on the oil cooler.

Thank you both! This is so cool, and I can hardly get in the woods to cut. I think the oils and alloy's in today's saws are so good that break in happens at a snail's pace. So slow that you can hardly notice it happening. The dyno tells no lies.....

Chad, I have said this before: get a patent on that beach. The guy that invented the push button socket release for the Craftsman ratchet got screwed royally by missing out on patent rights... etc.

You guys wondering about break in.

I tend to think the seals do more to drag down the engine than anything else. I'm sure the rings getting bedded in makes some difference, but a new set of seals really makes the crank a lot harder to spin by hand when assembling an engine.

Truth. I have seen rubber seals cut a groove in a hardened steel shaft in filthy environment Ag applications. There is definitely plenty of seal friction...

I'm gonna go out on a limb here and say Brad is gonna get snowed under with folks wanting a 461 done.

Ok so the 461 is awesome. Now have we ever seen a 460 on the dyno? I'm curious since that's what most of us that build saws from junk piles still have[emoji2]

Glad I didn't dyno a 441, lol.

You would still have junk by my math ,but i am a junk man and i like junk

Very true, Randy. That's why it's essential to center a crank before installing the seals. The seals put so much resistance on the crank that you can't tell when the bearings are free. Great point!

460 is VERY good junk in my books! Might even see a higher max HP!

I'm too poor to buy a 440 and put a top end on. I think they have gold in them somewhere

A 460 I don't have, but would love to see my hybrid on the dyno. I think it would have a but more HP, but also at a higher RPM. The curve would be a bit more peaky though.

pretty sure that's what chad started out with was 460's

 

[Lignator]

if someone has a stock 460, i am modding one as we type. could compare. I would love to see how much power I lost!

 

[mdavlee]

Redfin has a hybrid that runs decent. I have a 046 but haven't done machine work yet on it.

 

[blsnelling]

Well, I do have my Dad's awesome running 1st year 046, but I won't use it.

Or chad with folks wanting a saw dynoed.

What I want to see is a back to back 044 12 vs 10mm dyno. I have a feeling the discussions on this site and reality are two different things.

So what's the charge to get a saw dyno'd?
