Husqvarna 372 XPW (True) vs 272xp "Torque Monster"!!!
ฝัง
- เผยแพร่เมื่อ 28 ส.ค. 2024
- In the ongoing saga of experimentation, ponder-ation, application, etc., I wanted to try my "patented" "Torque Tweak" to an older 2 series Husqvarna.
I had already done a few late model Stihl saws and my buddy Dave in Ireland's 357xp BB. This cherry 268/272 seemed like a worthy candidate. Supposed to be getting a 390xp in for a similar "Torque Tweak" update which will be a nice addition.
Timewise, I thought that the 272 was a touch faster and mentioned such. It definitely wins on the lowend grunt. That we all watched. This means that if a guy wanted to run a 36" bar on both the 272 will be a better choice.
A side note I forgot to mention - they weigh exactly the same fully fueled - @ 17 lbs.
Looking at the timed runs:
Insane-O S 372xp went 8.09 down and 7.75 up
Psy-Ko 272 Torque Tweaked 272xp 8.04 down and 9.20 up - lifting log off
7.58 up foot on sawbuck
8.10 & 9.22 up
No need to mention the pulsating on the throttle rocking the log back and forth while the weight was resting on the chain.
Yah, stopped the chain - but - the whole process rotated putting the chain in a bind in the kerf.
I did mention, twice, HOW well pleased the "Torque Tweak" version of the 272xp turned out. We all watched it happen.
I'm currently available for custom saw modifications. Please shoot me an email if you are interested.

Looks like that chain cutting pretty sweet after all! Love those old Swede rippers, especially that 272!
I’ve run 5 tanks of gas through the 372 in this video. It just keeps running better. I am extremely pleased with the saw you built for me.
Both are really sweet builds, to my eyes/ears, but yeah, gotta love that low end torque! Beautiful work, Jack!
Loving the 272, and the xpw, both amazing runners.
I’ve running a 056 mag with a 32 Oregon bar for 15 years. I think I need to get something lighter weight. I can’t imagine flicking it around like that. Great videos
Still running two 056 mag II's there heavy but such torque monsters...better then my newer 066,661 (this model is a joke)...and our Husqvarna 390 and 395...only saws that I have that give the 56"s a run for there money are my two Husky 2100's...there the bomb... 30 years later still the bomb!! Shoe
Great video. The 200 series husqvarna were torqued out of the box but man, you get one that's been ported, they're down right scary! Love my 288, I save it for those special jobs.
Wow awesome builds, great job!! Love those older Huskies....
Afternoon Jack, the first saw I got from you was a 372 XPW which I worked for 5 odd years and led to a few more from you some 9 years later ! Both good saws but that 272 is quite special, now I know why you mentioned it ! The 357 is waiting to start work and indeed another special saw from the short test run it's had.
Dave hi.
I couldn't remember when the first saw made the, across the pond, voyage.
I'm cautiously optimistic you'll be well pleased once the 357XP Torque Monster gets a mouthful while you're on a "prowling" (Dave's word, although I really do appreciate it) mission.
This 272 is kind of a Monster as well. Maybe you need it too, lol.
Thanks for watching.
@@hotsaws101 Friend, how best to position the L nozzle .....?
@Sensei948 hi.
How are you not getting heat form that tuner who uses the same avatar?
You can set it wherever you want. There is no way for me to tell you it is "this", and it is "this" every time.
The chain is going to play a huge role in the process.
Also, thinking that I've gone down this same road with you numerous times before. My stance is not going to change.
The link to the video shows how I do it. It is the same every time when doing a one time adjustment session on a saw that is broken in. On all saws that allow the operator to adjust the needles that is.
1st. Get the low speed circuit set. I like the saw to drop off of high idle fairly quickly. No Da Ding Ding Ding Ding Ding like what can be seen sometimes on a 2-cycle dirtbike.
One or two then they hit lowspeed idle.
Adjust the high speed circuit according to how YOU want the saw to perform.
I never owned a tach until ~ 4 years ago. I tuned in a falling application by ear. This requires the chain to be dialed in. It is what keeps the engine in check.
An audible miss at high idle will net a good running saw. I've found they will last a long, long time as well.
I've never, sans the 346 in the high winder series video, melted a saw down. I did it on my 346 purposefully.
I'm not into "x" rpms personally. The factory says 13.5K for the upper limit on the 372 series saws. It would depend upon the saw's state of tune however.
Some saws will run better at a different rpm level than others. So,,, having the saw testing done where the saws are at the same rpm is not necessarily fair to both.
You need to experiment. Because again, there is no "x". It's get the b&c on, go use the saw while listening to it run. Again, audible miss at high idle, freewheeling.
The assumption here is that the saw being tuned has the b&c on with the chain tension is set for use.

Thanks for watching.
When you said flow over compression on the 372.. out the 50mm I’ve done the ones that I pay more attention to the transfers on I feel are stronger. Seems they really benefit from the transfers, exhaust and intake mods. Either way those are some killer builds you’ve done there 👍🌲🌲🌲
Jack awesome comparison. That air filter is cool on the 272.
I've been considering a mod like your "Got Flow 2.0" on my 395xp. Do I need to worry about venting air from the built in "Air Injection" if cut out too much?
That'd give the ms 500i a run for its money... Can't wait to see what you'll do a 500i when you get your hands on one 👍 Nice work as always!
You may not have to wait long......
Is there somewhere I can go read what your different porting terms refer to?
David hi.
Not really. Seems like most tuners use levels. Level 1. Level 2, etc.
I have names. Insane-O, or Insane-o-ized. That one is in the middle at 3rd.
Insane-O SS is 4th on the list.
Psy-Ko, or Psy-Ko-ized is 5th on the list.
Psy-Ko S is a ½ step up.
Psy-Ko SS is the top of the heap.
Thanks for watching.
Looks like you're crushing on that 272 Jack.
WTF hi. I had a couple when they first came out. Zipped with a 32" they were a nice little saw to pickup a corner and/or deal with some small wood (well what was considered small back then anyway).
They do have nice flick-a-bility. Great for limbing.
Thanks for watching.

You're one hell of a saw builder. I'd love to have you build one of mine. How about my 500i? Lol
sparker2289 hi.
My contact information is in the description area. Please shoot me an email.
Thanks for watching.
Great video again! What tachometer do you use?
Nice work on both saws. Are they running 7 or 8 tooth sprocket? Thank man.🌲❤🌲✊
Watching you run those sweet saws makes me wish I hadn't retired 6 years ago. Nah, just kidding. I'm done.
Steve T - I LOL!
Thanks for watching.
Your back will remind you if you forget!

@@Sensei948 hi. That is a really tight window in the rpm range, all things considered.
What you ask is virtually impossible for me to tell you "over the phone".
Generally speaking on saws that the operator can alter/adjust the low and/or high speed needles:
The saw needs a slight burble at high idle. Where that is with your mo-chine in your location (read - elevation, humidity, barometric pressure, etc.) is hard to tell.
The state of tune and/or amount of run time and/or condition (mechanically - maintenance) and/or condition internally (read - fresh, tired, clapped out) will have bearing on where the saw-weet spot is in the rpm range as well.
The screen/s should run at a hue of a brown paper bag. That "usually" nets the correct plug color.
Most of the time (again generally) having a slight miss at wot (wide open throttle) is about right.
The aforementioned points of interest will usually hold true for all saws in their various "condition".
In the end, and with saws that the operator can "tune", the guy squeezing the trigger will need to alter fuel input and find the sweet spot.
Thanks for watching.
Jack, do you prefer replacing decompression valve with plug on 372?
Hi Jack have you zipped any more 572s and if so what do you think of them? Mine seems like a heavy built saw. Thanks
Hey jack! Just curious.. what is your all time favorite saw that you have built?
how did you install the air filter dales some husqvarna 272 base
Very nice!
What did you do to that 272 its a freakin monster!!!
Thank you.
I tuned (ported) it up.
They will "come around" nicely once properly "did".
Thanks for watching.
What other full wrap bar would fit on a 272xp? Maybe a 395xp full wrap?
Friend, what the best speed max for 372 xp oe 2003
13500/13200?
How many bar plates does the 272 got on it I just recently got a 272 and trying to figure it out
Its Trollen hi. They have one version where you run an inside bar plate only. The other option is to get the "big kid" pair that are an inside and outside matching set. These work better at keeping the chain in the rails.
Thanks for watching.
I have a 272xp that my dad bought when I was a little kid, he hardly used it. It's a great saw and I've been using it on the fireline. I love it but it would be even better if it had a full wrap handlebar. Is there a full wrap for another saw that will fit it?
Daniel hi. I think that the 266 version with the spacer will work but good luck finding one of those. I think that the super early 268 handles were like the 266, but cannot remember. I did not use those much since they were too small of a saw for most of the timber we were cutting back then. The late version 268 is the same as the 272.
The only other option is to weld up a set.
Thanks for watching.
@@hotsaws101 Friend, how best to adjust the L-needle in the carburetor?
@@Sensei948irst close it fully then open up 1 1/4 tweak from there
Where do u get those k&n air filters ive got 266xp that i put 272 big bore on it an want to get more air flow an ive looked for something like what ur running cant found it.. was thinkin using air filter off valve cover on a 350 chevy
You have to make a velocity stack to mount the k&n on.. My buddy Red Beard Saws on Facebook 3D prints velocity stacks for most models
@@patrickallred850 thks buddy everyone talks about likes its made somewhere.. ill look ur buddy up but i can fab something up
Sir which one is best
What are your thoughts on the Husqvarna 257? I got one for free that doesn't have an air filter or chain tensioner, so I'll have to buy those for it. I've heard mixed opinions on it, though.
J. T hi.
Honestly, I've never run one. When they came out, we were felling way to big of timber to use one.
I did have a good running 262xp for swamping out, cutting trails, and the once in a blue moon corner-o-crapp on the edge.
It would handle a 28" decently.
I wouldn't worry about all the hearsay. If you like it, then hooray!
Thanks for watching.
@@hotsaws101 I'll let you know how it is after I get it fixed.
@@TheWoodsmanMilling If you’re not happy with it as a 257 you can always make it into a 262xp, it’s not that hard. My current favorite firewood saw is a 262xp that I built from a burnt up 257
@@dieseldave71 the one I got had only been used once, but it was left outside for 15 or so years. The internals are all good, but it's leaking fuel. I have got it to run, and it seems like it'll be a good limbing/light use saw.
140psi Good compresion 372xp oem?
Good job ! What do you think about 365 x torq?
Balanel hi
In all honesty, I think that they are lagging even more than the 372 x-torq. I quit running Husky after wearing all my true xpw saws out.
Never used an x-torq felling.
Of course I am only speaking from a zipped saw perspective.
Thanks for watching.
where do you get the air breathing mod on this saw? I have a 272XP.
Tjackson hi. The main part is a velocity stack.
Turn it on a lathe or get lucky and find one somewhere.
Thanks for watching.

Kilikina hi. Really, really close that's for sure. The times are in the description area. But, not putting to much pressure on the 372 bars. It would have slowed up tremendously had I done so. Is the 372 a slouch, by all means no.
Maximum pressure on the 272xp Torque Monster bars. It still tractored right along - especially with the rocking action where it took the weight coming back which equals a lot more force than when its just a static load.
If they were to get a taste of a 42" bar the 272 would be noticeably out in front.
Thanks for watching.
👍
How do I go about to have you modify my Husqvarna 572 XP .
Danny hi.
My email address is in the description area.
That's the best, first point of contact. Thanks for watching.
Do the lite weight Bars have much Flex.
Jeff hi.
Depends upon which version. The Sugi & Tsue, not so much. But they are more heavy.
The Stihl is in the middle in both flexibility and weight. The Oregon LW bars are the lightest by far but are far superior in "flexure" as well.
The Cannons are on the heavy side of the lw concept and a bit sitft from the look of them. Those two go hand in hand with current designs.
Thanks for watching.
Jack . 272 , Wow !
