Thank you for doing this for the saw community joe, you answered many questions here today. Some that's been lingering around for decades, finally we can put to rest that never ending xt vs oe argument. Now we know the differences, while the heavier piston on xt makes bottom end wear out sooner they're not that bad at all. Im humbled to be part of this, thank you again brother. Look forward to participating in more of your contents! You're the best!
It’s amazing the power increases you can get with these pipes. I definitely remember reading years ago on one of the forums guys saying pipes don’t work on saws and it would take tons of work to get one to work. Now we have technical data and graphs chucking that right out the window. THANKS JOE!
The pipes have to be matched to the ports. That is why the x torq is down on power vs the oe saw. Now I'm not sure how practical pipe would ever be in the woods lol
Man these videos have so much useful data that the saw community has been debating for yearsssss on the forums. You are the GOAT for making all this happen brother! It’s incredible how much power these saws make with a properly tuned pipe. Very impressive. Much respect to you and all the builders/owners of the saws that are being sent in.
Fantastic video. Peak performance through r&d makes for great content especially for ones like us who like to see numbers and graphs. When you get a port job and a pipe matched it’s going too be a ripper. 😎👍
A factory upgrade muffler for a 372 is to put a genuine oem 385/390 muffler on a 372… The outlet on the 390 muffler is larger and flows better. Just figured I’d throw that out there. Great video man this is really awesome content Joe…
Thank you for all the effort you put in this to get the info out!👍😎... amazing what those pipes do even if it’s not really a thing for a work saw! But 8hp on the ported saw as it is is awesome still 1 hp over a stock 90cc saw😯... start to think about getting a saw build from you.. just a Long way to get it shipped up here!🤦♂️🤣🤣... keep it up 👍👍
nice to see, that a good ported saw is not that far behind the piped one. if you think of working with those saws, a pipe is not really a practical thing to deal with in the woods, it's just for show and great to test like you did and for this the ported version is pretty much the best i think.
Yep, trying to help them dial in the pipe recipe. That way when they are ready to sell it is a true bolt on power mod. Unless just having fun or bucking logs in a lot the pipe isn't very user friendly. But it sure it fun to run.
Awesome video! I have always liked the OE 372 over the XT and you showed a striking difference in the weight of the 2 stock saws. Pretty much the same power but over a Pound of difference. 👍
The biggest difference was the unlimited coil on the original 372. That helps a ton with top end acceleration and limbing. The other part that was annoying was the X torq would burn up PTO bearings. My old original 372 then I got back in 2001 is still producing wood today. I blew up my X torq 2 times. Now it's in a landfill somewhere.
I have a fully rebuilt old 372 and I like it. It was a turd with the stock muffler but I stock on a dual port and it was night and day in performance. It's a good saw.
Thanks for the excellent testing. Personally I would prefer a broader powerband with the lower Peak number been a real high peak number in a very narrow powerband. Just my two cents.
i was looking at the ported saw with the first pipe and thinking the same thing. now we need a saw factory built with the pipe as part of the saw body/handle so it has pipe power without the bulk of an add on pipe.
Test cuts are still very important. A sharp chain makes all the difference. All the power in the world on a dull chain is slow cuts and lots of heat. I just leave the chain tuning to the end user.
14:45 one thing that might make easier for the viewer is if you use a highlighter and mark the peak numbers so its quick and easy to look across all the saws. Its something quick and simple but will add the the viewers experience.
Now I want my own saw dyno. Love the channel Joe! Do you have a video where you show the dyno in detail and how it works etc? I’d sure be interested in a video like that.
Nice Video again Dyno Joe. A thing that people have been taking about lately is the crank stuffers. You could test the stock 550 first and then take out those stuffers and see how those dyno curvs chance. Or a 545 and test it with stuffers. We'd love to se a video on that.
Need to shorten the header length on both tuned pipes to shift the power curve to match the natural peak power of the muffler runs. especially for pipe 2 but also pipe 1.
Great job Joe. Will the graphs be posted on you FB soon, kinda hard to see the numbers when viewing UA-cam on my phone. Thanks, have a great weekend 😉👍
Nope, it was always a good deal if you were willing to do the work. And while you're doing that you might as well mod the muffler and set the squish(don't do a base gasket delete without checking some are tight).
Thank you for your quick response!! in your opinion is one version of a saw, intrinsically better than the other. I’m pretty good at resourcing things. You mentioned that the X Torq would be fine given the fact that I won’t do any porting, however, is one version better than the other? Thank you again.
Are you having to tune the carb between pipe changes? A wide band O2 sensor would be nice for info. But have read the 2 stroke oil will ruin the sensor. With my Dolmar 120si and the hacked 50cc race dirt bike DG pipe I had to give both circuits more fuel.
Thank you for this wow!! If you were to get a new 372 today, would you look for a pre X-Torq or would you be ok with an X-Torq. I won’t port won’t port a saw either way.
If you are not concerned with porting the x torque will be easier to find and will be very close to the original. If you want to port someday the original is a better starting point
Awesome videos! I have ported a few OE 372 now. Got a couple X torque a friend was wanting. Do you remove the splitters for the fresh air ports? Contemplating ideas. Thanks boss!
@DynoJoeMods Fantastic content. I am on the 572xp and would love to understand what some piping/porting mods would do to the power. Also, how does autotune respond to "elaborate" modifications?
But the x torque held good torque and hp up to 12 and xp took nose dive! We all love the peak numbers. But hen I look at the graphs on your videos I try to look at the power band and see where I run my saws.
I’d like to mod out my 562xp mk2. I love the weight and usability of it and the power of a 572. What do you suggest for a 562xp mk2 to up its rev and torque and response without sacrificing its workability?
great info , why i look after my 2012 372xp ( i will port it one day, lightly just gasket delete and open transfers, should give me .025" squish) running with a 19mm ex euro type. Where do iget a high top and filter kit, preferably not chinese?
I was watching a recent Tinmans Saws video where he added a muffler based on a design by Ironhorse. Is there any chance that you could bolt on a stock exhaust vs an Ironhorse exhaust and see if there is much/any difference in performance.
I didn't build the pipes. These are mild steel looks like 18-20 gauge. These were just prototypes whipped up and sent in to make sure they were making power and going the right direction.
Unfortunately it's a shame. Nobody is going out in the woods to cut with a pipe like that I get your showing new products n such. But how about products the normal person is ACTUALLY going to use Edit..kills me to hear those internals in the recoil taking all that abuse when shutting off (I always pull the rope out) learned that after replacing a recoil on my dolmar 7310

i would march myself out into the woods with a pipe on my saw to buck up some logs. a HUGE pipe like that might not be the best for felling timber but it wouldnt be that hard to bring the saw with the stock style muff to put the trees down and then switch to the PIPE for bucking. with the gains you get it would save a lot of time bucking. I would just strap the pipe to my backpack that i take with me everywhere, and i already have the tools with me to change it out. im just saying that some people operate a differently than others.
Over 5 FP on the torque and over 9 HP, plus a broad power range. That's one strong saw. Thanks Joe.
Paveen ported up a monster 372, and even if the pipe wasn't matched to the ports it still made good power on pipe.
Very stout muffler saw too.

Great informative video for sure Joe!! To quote you on stock saws seeing the smidge diff between the two on dyno is non debatable LOL!!
Thanks for dynoing an OE and XT, been waiting on this for a while. Not much difference stock for stock putting a ton of urban legends to rest.
The biggest difference was the unlimited coil on the original 372. That helps a ton with top end acceleration and limbing. The other part that was annoying was the X torq would burn up PTO bearings. My old original 372 then I got back in 2001 is still producing wood today. I blew up my X torq 2 times. Now it's in a landfill somewhere.
@@austindenotter19 How does the unlimited coil help when it has less advance at lower rpm than the limited.
Thank you! I just ordered a 272 🙂
My 371xp came with the big air filter. Bought it brand new in '98
I have a fully rebuilt old 372 and I like it. It was a turd with the stock muffler but I stock on a dual port and it was night and day in performance. It's a good saw.

Wow dyno tests really make cutting cookies with a stopwatch seem so primitive. Of course the latter is still fun! ;-)

I'll have to get some highlighters.
The best part of a X torq is the bigger carburetor. We would rip out the dividing wall on the intake elbow. That helped them saws out a little bit.
Now I want my own saw dyno. Love the channel Joe! Do you have a video where you show the dyno in detail and how it works etc? I’d sure be interested in a video like that.

You may be able to order all the parts through a dealer. The high top on the oe saw was an aftermarket kit.

Hello
Would running the overseas muffler on my stock USA 372 x torq make it run better? With proper adjustment to carb ?
They were very similar output.
