Huskyboy meets the 572xp

[CapitaineHaddoc]

@CapitaineHaddoc in your typical 5h clean cutting time, does the saw have significant breaks between re-starts to where the engine cools off considerably? Just trying to understand the heat cycles that your saw sees in a typical cutting day.

It depends the kind of trees I have tu cut.

Yesterday morning I had small pines, all learners, and really close to each other, so I don't stop the saw until I have to refill.

Yesterday afternoon, I had a few nice douglas, and I had to hit de wedges or even use the jack for one of them, so I stop the saw. But when it's on the ground, I had almost a full tank for the limbing, so there's not much difference.

Last week, for cons, I had some huge beechwood to cut, but only a few trees on a very large surface, so the saw isn't running that much.

 

[TreeLife]

Yes, thanks. Still can't get that file to open. What that tells me is that the change was to the piston, not the cylinder because the piston part number was changed. Glad these things aren't failing, because the price certainly hasn't changed: $329 for a P&C kit.

Yeah, it sucked buying one.

 

[huskyboy]

I hope they come down on P/C prices, that’s an appalling price. Almost stihl esque dare I say (LOL). Granted the saws are holding up good so at least it’s not a serious concern at the moment.

Yeah, my saws failure wasn't operator error or the saws fault. Exhaust roof too flat lol all well

I’ve been kicking around getting a new saw, but I really am having a hard time justifying it when none of these have much on my 2171’s.

I hear ya. I have 3 2171’s, 2 with heat. All ported and run exceptional. I’ve been kickin around getting a 572 myself. Just not sure if it’s a good idea

 

[huskyboy]

A stock saw is no comparison to a ported one. A stock 572 wipes the floor with a stock 372 and uses less fuel doing it. A ported 572 and ported 372 are about the same level of performance even though the 372 was less powerful stock. This is because the old style saws have more potential modified for several reasons. No strato, no autotune ect.

In those terms, it really looks like the 2171 is where it’s at, but the numbers are off by a bit, and the AV and fuel efficiency is much better on the newer saws.

There is more to it than just cutting one or two seconds faster in a cut than another saw though lol. If your using the saw for several hours a day the ergonomics are a consideration. Saws like the 572 and 462 aren’t a mind blowing gain in cutting speed over there predecessors... but yes they are a bit quicker in stock form. But the main improvement was that they are more comfortable to run all day. There a more efficient package. Imo they made the electronic carbs more reliable and refined than previously as well. If your just a hobbyist, then some of that might not really matter as much to you. You might just want a “hotrod” to run for a hour or two every weekend or so in the fall. For a serious user it might be different. That said, “old school” saws like the 372 and ms460 still get things done. Just not as many bells or whistles.

Agree . The 576 gets a bad time on here and else where but run one for days on end and the superior anti vibe ( still unbeaten in any saw I've run) and ergonomics come into their own . Run an 044 or 046 beside it and they might have a little more power but at the end of the day you feel way more worn down by them . Of course I might not be as tough as some guys on here

I've logged with ported saws. I won't again. Chasing the fuel can around all day outweighed the gains you got from the porting. Not saying any of what you said isnt true, just my opinion from the logging mtns of PA WV VA MD.

Makes sense to me. That’s why I left one of my 572’s stock with only a muffler mod. It still has good power and snap imo. I grab that one when I know I have a long distance to go. The 572 is a miserly saw though, even my mildly ported one is not too shabby on fuel. By the time it runs out I’m about out of “gas” myself and fill myself up lol. I can comfortably keep ahead of the skidder felling trees or forwarder guy bucking logs usually.

 

[MustangMike]

Maybe I'm just naive, but I find it hard to believe that most properly ported woods port saws won't put more wood on the ground tank for tank than an unported saw.

It would be hard to do, but I would like to see some king of controlled test on this.

 

[ferris]

@MustangMike
The saws are more efficient when they come from the factory.
Maybe u gain 40% of more performance compared to stock. But I would bet 1000$ that the fuel consumption is 50-70% over Factory stock.
Stihl and husky putting tons or R&D to get the saws in the epa regulations and make them efficient as possible.
No porter can do this

 

[RI Chevy]

Some porters can. Think of it like an orchestra. Everything matching up perfectly.
My MOFO 026 is absolutely amazing with power and fuel consumption. You have to experience it for yourself to believe it.
On the other hand I have some ported saws that just guzzle fuel.

 

[CapitaineHaddoc]

I can assure you a ported 562 will put more wood on the ground than a stock one with the same amount of gas. The same with a 346.

A ported 6100 or 7900 is another story, they're really thirsty.

 

[Sawrain]

If it’s anything like the automotive/industrial world from an EPA standpoint exhaust emissions trump fuel efficiency, and fuel efficiency can suffer as a result.

Best emissions (least harmful) and most efficient use of fuel don’t go together.

A Simple example being NOx Emmisons, high peak combustion temperatures cause their creation, so simple fixes to please EPA regulations are retarted timing and lowered compressions ratios to keep peak temps below NOx Creation thresholds, unfortunately peak temps are a factor in an engines thermal efficiency, higher being better.

Same with air fuel ratio, different for best emissions or efficiency, more of a four stroke consideration this one though.

The freedom aftermarket porters have that OEMs don’t at least gives them a chance to compete when talking fuel usage.

Didn't read all, but sory to hear you lost a saw, I think I read it
was a porting misadventure, is this so.

 

[MustangMike]

None of my ported saws loose anything close to 40% of run time. (The exception may be the 660s when milling).

I know the new saws are getting better, but I'll bet anything that a porter can improve the efficiency of most older saws as the port timing on them was all over the map!

Also, knowing that the EPA just compares emissions to saw displacement, (w/o any consideration of efficiency) it is not hard for me to believe that additional efficiency can be obtained. In addition, your time is worth something also. As my Dad used to say "You can't buy more of it".
