575XP help

[ShoerFast]

Cutting with a friend that has a just broke in 575XP , that I was not impressed with, but I don't know much about Husky's .

We timed some cuts, traded stop-watch for saw and found we were close there, ran it against my 361 and had a fairly consistent 7 second -to- an 11 second difference (575 at 11 seconds) In about 14" of Douglas Fur. I'm just wondering what we could do to pick the 575XP up a little?

All we did so far was tweak with the "H" and picked it up a little cut time, what is next?

Gut the muffler nad put some holes in it.

Past that sending it to one of the numerous builders out there.

Has anyone figured out how to mod these Strato engines yet?

I did not even know that it was a Strato engine, pulls well at most RPM's, but dose not pull hard.

It the muffler crimped like a 361 / 290 - 390? , (Search is not working the last 2 times I tried)

so a 361 outran a 575? by 4 seconds in the same wood, with comparable chains?

Not completaly compairable, a somewhat rocked out and doctored RS on the 361, and fairly new Oregon chisel on the 575,,,,, Equal sharpness, but I would put a little more angle on the Oregon chain if it were mine,,,and the 575 cut better.

I'm not bragging the 361 up here, I have no doupt that the 575 should beat it hands down, it just dosan't

That's what it sounds like. Duck! Here comes the Husky crew! :hmm3grin2orange:

I'd check the compression on the 575

 

[sILlogger]

im just thinking of one of the logging crews that i cut with the run 575's and i always give them a hard time around running sissy 'lil hedge trimmer saws!!!

then again i run a 660 w/ 24" bar and used to have an 084 wearing the same length

Oh that would be classic! If the 575 had low compression, that would be huge rock for the Husky crew!

It pulls over like you would expect it to pull over, starts fine, will idle forever, just not a lot of power. There is a chance that I did not get a good tune on the "H" but it seems the fastest I can get it in a cut.

 

[rahtreelimbs]

The 575 has never been known for stellar performance............at least by the few that have ran it on here!!!

I believe JP Hallman was the one and on advocate of that 575!!!


But a 361 over a 575..............pretty doggy!!!

The 575 has a rev limited coil and you may be leaning the thing out way too much. If it's getting whomped by a 361 it's probably a cut or 2 away from blowing up.

No way a 361 should beat a 575, and that has nothing to do with the usual brand argument. 357 isn't going to beat a 441 either.

If that Oregon chain was new, it may be an idea to take a look at the rakers.
Some of the 73LP chain I have gotten lately has had way too high rakers (5-10 strokes needed to get them right)......

5-10 Strokes WOW is there any raker left when your done??? I can see a few extra strokes on the 73V because there is just more meat to file away. But on a LP chassis 5-10 strokes would have you below the depth gague on the driver itself. LP is a dual raker (depth gague) chain.

Unless of course your raker file is too dull

The file was not dull, but slightly used, I use the 8" variant (Husky), and change them quite often - btw, the LGX chains that we got from you were perfectly OK.

On those LP chains, the real rakers is still quite a bit higher than the ramps, and they will stay higher until most of the cutters are used up, ime.....

I was going to say that!

Ok something has to be wrong with that orange saw come on. I would make sure everything under the side cover is ok and go from there. set it by ear till she four strokes and back off. Take a good look at the chain/bar and make sure the bar sprocket is not binding. try a brand new chain set the rakers to the right depth and see what happens. Is there a 7 or 8 tooth sprocket on her? look at the bar and dress it if necessary. You may just have a good strong 361 and he has a doggy 575 but I think something is not quite right with his saw. If nothing else bring it in under warranty.

 

[sILlogger]

or maybe it is that them d*mn high revving, ear piercing, screaming 575 is vibrating itself apart like i have seen several of them do....had a buddy of mine has the piston come apart on one the other day....piston broke clean in half...wish i had some pics

hey, this is my 500th post....i need to get a hobby

It really seems like a runner, we can get a real good burble, fattens up well, the fastest we can get it in a cut is slighty leaner then "to rich" Bill, my friend never thought anything about the performance, and really is stihl not displeased with his saw, it is a runner.

Could it be that were running at close to the 10,000 MSL line on the mountian? Or will a non-muf modded 575xp not wake up?

Were dose the limiting coil start to cut them back?

 

[manual]

13.500 rpm
If you don't use a tach. Your not getting optimum performance.

 

[Grande Dog]

If the horsepower required to cut your 14" is less the horsepower of both saws being tested, the saw with the highest chain speed in the cut is going to be the first through. Now if you wanted to put a larger sprocket on the higher displacement powerhead to make use of the additional horsepower converting it to chainspeed, or make your tests on piece of wood 24' in diameter. I'm sure your results would be the opposite. I'm not trying to defend or attack one model or brand because this will hold true.
