- Finished a pair of brand new husqvarna 395xp. Machine work, full porting. muffler mod and dyno time.
Very nice gains to be had porting these saws. Much stronger than stock, pull long bars, more efficient cuts.
Great option for large tree removals, and heavy duty logging operation. Or if you just want a big bad saw!

I developed that intake design about 30 years ago with great results in bigger wood! Glad to see it catching on! He’s gonna be happy with both saws! Good job!
Seems to work well on this 395. Never bothered playing too much before. Now is the time to see what things are actually doing inside these builds.
Well , they say “talk is cheep , it takes money to buy whiskey” ... looks like the added flow on the intake added some gains! I think Ol Harvey can pour himself a glass of Tennessee ol #7... tape (or in this case , the Dyno ) don’t lie ! 😁. I’ve said for YEARS .... little things make BIG differences!
Amazing build. You and Ironhorse are inspiring with your builds and knowledge.
What a great resource of information, thank you for the service you provide. Extremely interesting to see some quantifiable results. Keep up these excellent videos, we appreciate the time and effort that goes into making all of this happen.
Thank you
@@dynojoemods2764 Great content! The 395xp is an amazing platform!! Do you take saws from all over to port?
Nice work Joe . Really enjoy the dyno runs
Well done, amazing closeups and details.
Very cool content Joe, can’t wait to see more dyno runs!!!
Crazy power! Nice work Joe!
Hey Joe. Thanks to this Video I've changed up my 395 porting recipe and just built 2 wicked saws for a couple of mates. Both of them are better than my own 395. These are the most helpful videos on the net bar none!
Really having a lot of fun seeing these different variables with many different saws. Great advice on the muffler mod as well.
Glad you enjoy the content.
Thank you for watching
Great testing Joe.
I've been told by more than one in the know to keep the uppers flat. That test proved them right.
Holy fudge! If I ever get a 395xp I know where it’s going to for a little vacation!
I'm surprised you don't have more subs. I love this kinda stuff!!
I've only been at this for 6 weeks. Growing pretty well.
Beautiful work Sir!
Thank you
That shaping appears to make a pretty huge difference. Wow.
Another great Dyno Joe vid! 👍🏼👌🏼
Thank you
Husky always number one 💪💪
Interesting results. Proof is in the pudding. Keep ‘‘em coming 😎👍
Awesome work and video!
👌🤝🤝🤝
Thank you
Thanks Joe good info. I thought that beast was gonna throw a chain on the dyno there for a second😆 I imagine it’s difficult positioning so many different variations of bar chain combos to fit your machine!
Yep it can be fun making sure things don't derail. I had been spoiled with lots of inboard clutch runs.
iron horse uses heart shaped intakes like that. well theres the proof clearly it works. another awesome build btw
wow truly amazing results, surprised me also
Some of these big saws gain well.
I think all your videos should have the Dyno Graphs! They are really nice to look at and comprehend all the data!
I try to include them on all of my builds. Great way to make sure I am going in the righr direction
Great video, awesome work.
Thank you
Nice work! Subtle changes moving in the right direction.
Thank you.
It is the little things that all add up.
Just a matter of trying to get them working together.
@@dynojoemods2764 Truer words have never been spoken. 👊
Nice video thanks for sharing! 👍
Thanks for the video man.
Nice work and really appreciate you sharing all of that. Of recent I have been CNC milling the combustion chambers and experimenting with the differences. With out a Dyno it all becomes a little cloudy and opinion based. But as best I can tell compression ratios around 9.1-9.5:1 with a squish band of 40% area seems to be giving me a very sweet running saw that revs freely. Not a big fan of over compressed saws. I've gone as far as having them run flat on top. Stock saws are about the 9-9.5 range as well with the squish set up properly.
Of late I have also been experimenting with transfer angles. For some time I have been angling the auxiliary port slightly up and been claiming a boost in torque. Very nice to see some confirmation on that.
I have been toying with the idea of building a Dyno for sometime for exactly the reason you demonstrate here. No bullshit no arguments just hard data. Love it.
Subscribed and once again really appreciate you sharing like that. Nice work on the ports too!
Thank you
What’s made the difference is basically what iron horse has always claimed works! Interesting numbers man, very interesting builds
All the pieces add up.
Machine work, adjusting the port time, adding more area. It all plays a part.
@@dynojoemods2764 great work man, your clearly getting the results
Awesome job 😎👍.... 10 hp starts to get scary!😂
great video!
Thank you
Awesome content Joe! I'll definitely be stopping by to say hello!. Let's go Blackhawks LOL. Take care Sir 🙂
Best channel ever
Thank you.
Joe I’ve really enjoyed these videos thanks for doing them. not sure if you are doing this already but running each saw 3 times and averaging the numbers is probably a good idea just in case there is any variations in the run. Heard you are getting some iron horse saws coming too!
Thank you.
All the saws get 5-8 pulls and I pick the 3 most consistent time/power runs and pick the one.
So I try to avg them the best I can. I will have to try using the avg function on multiple saws sometime. Only ever used it on single saws. Bit if I can do multiple on the same graph then that makes it simple.
@@dynojoemods2764 i just done a 395 no machine work i dont own a lathe..base gasket delete and mild port and transfer work blew my mind at how well it turned out....thanks for sharing this info!
Awesome vid. Id like to see a run with the muffler mod only. If its 60% of the gains for a fraction of the cost, its hard to justify the port work. Of course y'all need to eat too and all 😅
Muffler mod is normally the first 5-7% of power gain. Typically 0.5hp or so
Nice👍👍looks like my theory on transfer angles stand up on the dyno ive honestly never tonsled an intake though....
Angles, shapes, direction all matter when it comes to 2 stroke ports.
That is all part of the fun trying to put the puzzle together
@@dynojoemods2764 exactly!
10.2! what a hoss.
Very nice gains from this Pair.
great channel i really enoy watching your content. one thing i would like to see a video on is a muffler comparison on one saw, so we can see how the saw reacts to doing different things to the muffler. like stock vs what you do to a muff vs bark box vs opening up the muff as much as humanly possible, maybe run a saw without a muff, vs putting a pipe on the saw like dirt bikes have with the expansion chambers. i think that would be awesome to see the results of that in a video.
Thank you.
I have some stuff like that coming up.
Good stuff, ask the pro types.

Would love to see a stock ms200t vs a fully built ms200t on the dyno. My ms200t has had pretty much everything done from intake and exhaust polishing/porting, timing advanced and cylinder decked etc. Never ran it as a stock saw and always wondered how much more power it made. Work was done here in Canada by a reputable shop so would probably be about an average in performance increase. Thanks again your channel rocks and is going to grow huge as saw guys are going to love the content
It seems to be pretty hard to find a 100% stock 200t lol.
@@dynojoemods2764 I have one I’d let you use.. just throwing it out there.
@@Houseworksaws
Might have to take you up on that sometime.
I have a stock 395 with the dual port muffler and she RIPS!!! Id love to have a little mild porting done as well.
I just built a ported one. It pulls a 42” bar like a freaking freight train. Heavy as a cinder block, but man is it a fantastic stumping saw! DEFINITELY get it ported!
Im thinking to hire someone to do it for me. I’m perfectly comfortable porting old iron chevy heads but a 2 stroke requires more finesse.
@@VinnyMartello and a degree wheel to make sure you shave it a few thousandths at a time until it’s exactly where it needs to be. Definitely!
Hey great channel......seeing dyno results like this can really help me decide if the high cost of saw work is worth it for all my saws. Thanks and God bless
Thank you.
Just let me know if you have any questions.
Thanks for another interesting video. The workmanship on your cylinders is exquisite man, really something to aspire towards as an amateur porter 👍🏻 I’m about to start grinding on an MS382 this weekend and am going to give that heart/tonsil shaping on the intake a go.
Just out of interest do you run these in and allow the rings to seat before you dyno them?
Thank you.
I think the 382 may have that shape intake to start. Just watch the ring locating pins.
I do a warm up, couple of light pulls then the full pulls. They will still break in some with use.
Yes Please let us know if the owner can feel a difference cutting the wood. thanks
OMG 10 hp??Unbeliavable!!!!!
The difference between stock and ported is the big thing to look at..
The numbers are nice but the curves vs stock tells the story
@@dynojoemods2764 Yes the difference is insane here…Did you try to port the 592??Im so curious what this saw can do with a good port work…
@@dynojoemods2764 this is SOO important. the curve. usable range. Your on your game.
coming from a drag race background, Peak power isnt as important as the curve. engine still needs a wide band and to be able to recover on rpm.
love your channel
Joe
I’ve noticed that your set up on the Dyno. The chain breaks over the front of the bar just prior to the chain reaching the dyno.
I think that could be eating some HP as the friction there has to be severe!
Not knocking you at all just an observation!! Love the videos.
I would love to see you port and tune a 460 Rancher. I bought one brand new and I’m disappointed in the power it has!!
Thanks
Andy
Yeh, the one is an ugly setup.
But it dosent pull that bad. I have tested the same saw a few different ways.
The bottom of the bar is tight and it is only grabbing with a few links in the bottom half of the dyno sprocket. The drive sprocket it actually trying to toss the chain off the top of the bar. I run the chain a bit on the loose side too.
I will be porting the 450r the little brother saw
@@dynojoemods2764
Hey Joe
Yeah I noticed on my 460 that it has what looks like bolt on transfer ports. I don’t know if that good or bad but at least it may give access to do the work needed in those areas ?
I’ll stay tuned for the 450 build.
I’m really enjoying your videos just actually found u ! Iron horse and you are an encyclopedia of knowledge , thank you . I’m redoing saws for local tree guys . I’m having a problem in my own head on how to come up with timing numbers. And what each thing u do does to affect each reaction to saw . Any thoughts . Also my 395 I’m doing now has numbers at ex 110, int74, 128 on trans. Sqish is .034, , my thought is it would have low end but be a turd in upper range , your thought . And what would u do for numbers on that 395? Thank you and keep up the Awsome videos , btw is that a prony brake u use ? Can u do video on your dyno ?
Great channel,when you say up are you referring to the top of transfer angled more towards the squish band? rather then the other cylinder which I'm guessing would be flatter.Interesting concept whats going on in there working with the intake shape.Have you had a 038magnum on the dyno yet.Keep up the excellent content.
Yes, up would be towards the squishband.
No 038s on the dyno
Joe, I noticed you are recording 10 - 15% more hp on the larger Husqvarna saws in stock condition than the manufacturer publishes. Any guess as to why (different fuel and/or atmospheric conditions)? Have you had your dino calibrated recently?
You are a great resource for us saw junkies, keep it up!!!
Thank you.
I would guess it is a little bit of a lot of things. Not knowing how many data samples husqvarna uses. Or the test procedure it very hard to duplicate. Dyno is best used for a before/after or simple changes. The difference is what matters most.
I check calibration often just to be sure. So I can use my old runs to compare.
Nice video, thanks for sharing. What size would you say is a good size to go for when adding another hole to the muffler (as in percentage of the exhaust port size....)
In your opinion in the bigger 90cc saws is more or less blow down better. I'm running around 18 to 20 degrees with a 99 degree exhaust roof with about 165 degrees of intake duration. Also did the finger port design on my intake with a small boost port on piston.
I tend to stay 18-20 bd range on the 395. Makes a good runner.
@@dynojoemods2764 thanks for the info I appreciate it
Would you be able to speak to your dyno setup? Such as what you're using for a load cell and the data box you're using?
It's always great to see an engine builder with a dyno.
Here is a short video telling all about the dyno build.
If you have any other questions let me know.

@@dynojoemods2764 Thank you! We're in a similar situation with our 9" Land & Sea dyno. The data boxes are failing and we're looking to update a bit. Did you stick with land and sea components when your torque arm started having issues or did you change to something like performance trends or yourdyno and get a different load cell?
@@BarskiX
Welcome
Hmwfllc@gmail.com e mail me if you need more info
I tried a 2nd tq arm but it did not last long.
I switched to performance trends complete setup. S beam load cell and all. Has been great for over 1200 pulls. I have a 2nd brake I want to set up too, and will be using them again too. Worth looking into for sure.
Hey Joe, I have been looking forward to the 365 chassis experiment, you had earlier suggested. Is it still on queue?
Great work as always!
It is. Have to get a few customer saws through, then I can have some fun. That project will take lots of time to test all the cylinders.
Waiting on that test a well! Thanks Dyno Joe, nice looking 395 builds btw!
It's worth the wait. Thanks Joe!
@@dynojoemods2764 I just got me a 365 Xtorq, love the smooth strong power it has! Could you build a muffler for my saw?
When we getting the dolly 73/79 stock and ported on the dyno 😁. so what is giving the little boost transfer angle or intake I guess a combination? ...interesting stuff though👌👍
Waiting on a couple other straggler 70cc saws.. But they are coming.
👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏
what did you end up with for intake / exhaust duration? if you dont mind, thank you.
I find your vids really interesting. I’m curious why your stock numbers are often a good bit higher than the factory says. Are they really under rated or is it something to do with your setup?
Thank you
Mostly to do with the setup.
Some are closers than others at times.
Big thing with the dyno is to show change, not the absolute number.
Like the 395's in this video. The 28-30% increase is much more important than the 10.x hp made.
But they are both fun to look at.
Love the channel!
Does any current production saw have more potential than the 395xp?
Strongest ported 90cc has been an 066 as far as hp goes. But 395 not far behind. 592 may change that
@@dynojoemods2764
Awesome. Looking forward to seeing that 592 back on the dyno after it gets worked over
Hey Joe!! Few questions I you don't mind?
Husky 380/480's? Worth to modify and keep cutting with them or upgrade to a newer saw?
Same question to an old Jonsered 910e?
I don't do the older saws for customers.Too many hard to find parts/pieces once you take them apart. Always seems like they need some mount or gasket that needs to be tracked down to get the saw back running.
Once ported the saws generally run harder, with more pressures. Seals and gaskets can become an issue on old saws too.
Interesting upper transfer angle, be interested to workout if it was intake or transfer angle or both to thank for gains
Probably a little of both.
@@dynojoemods2764 👍 looking forward to seeing Paveens monsters dyno run
Also squish is 25. Jus curious on your thoughts on best numbers in your experience for best performance for strong work saw
That all adds up to a nice strong 395 pretty close to where my 395 builds end up.
What is your reason for not messing with lowers to much? Like thinning the bridge and widening
I widen the lowers some but don't go crazy. Just not worth the extra effort to hog them all out.
Do stock vs ported Husky 572xp and later stock vs ported 592xp
I do have a 572 coming up might be able to get some footage.
Is there a waiting list
Will a ported 395 handle a 9 pin sprocket and would you have to modify anything for clearance with it?
Depending on bar length and chain setup it can. Have to watch chain tension the bigger sprockets are larger than the tail makes it easier to toss a chain.
What's a good cylinder and piston for 590 echo, that would be good to port on, I don't know what to use, and I don't have the tooling you have
Only good options are oem echo parts. Nobody makes a cylinder for them. 1 aftermarket piston is avalible I believe.
hello
could you please make a video of the Husqvarna 372 please. stock then with the iron horse muffler and then ported whit the iron horse muffler
It will probably be a little while before I get into porting a 372. But muffler mod testing sounds fun.
Hey Joe,
Just ordered a G395xp to experiment with......based on these cylinders you ported in video, what would be good numbers to shoot for on intake exh and transfers? if you don't want to share exact numbers it ok, but if you can get me close would appreciate. thanks!
99,120,78-80 are pretty solid numbers on the 395
@@dynojoemods2764 thanks Joe!
Old vid but why not open the bottom edge of the lowers? I’m sure there’s a reason. Do you think it would start okay without a decomp?
I'm running mine without the decomp and it's not pleasant...
Another great vid.
Any gains to be had in an old 371xp?
The 371/372 non x torq gain very well. I have not ported an x torq 372 yet
@@dynojoemods2764 I'd love to see results even from a muffler mod.

Awesome video Joe.... Are these stock bore or big bore? Flat top or pop up?
Thank you
Stock bore, stock flat top piston.
@@dynojoemods2764 thank you what's your builds with a big bore pop up putting out for hp and tq....or are you recommending stock bore flat top builds?
@@kevinz763
I don't like to build aftermarket cylinders. I'm not opposed to a piston swap in a used saw. Most of the saws I do are new 95% of the time.
Wouldn't mind seeing a test between the Ms 362 an 400 with the husky equivalent
Working on gathering all the 60cc saws.
Thank you
I guess now you’ll have to retest only doing the “Mickey mouse” intake mod. Just to see if the gain was from the upper transfer work or from the intake…
So the stock xpg is close to the same as the Xp for less money and that would be the saw to buy and not spend 1200 ?
Xp and Xpg are the same engine, just the xpg has a generator and heated handles, and carb element. For nice toasty hands
How much does it cost I have one and needs to be rebuilt 😢
Would you port 395xp saw differently if you're using for milling vs work saw?
I would port it a bit different. Maybe even more open muffler mod to help let the heat out.
@@dynojoemods2764
Thanks for the honest feedback
What were the numbers on these test?
Did he notice the power?
So where can I send one of my saws to get this done?
Which part?
I can fit dyno runs in pretty quick. But am booked up for Port work pretty far out
Why didnt you port the lower transfers?They are the biggest limiting factor of the 395 compared to the 394s, the transfers are tiny
They are opened a little. But no need to go super crazy to get solid power.
In your opinion which saw would you recommend for milling, 395 or 592?
395
@@dynojoemods2764 becouse or the carburetor?
@@Kolsch221
That is a big part of it. Adjustable carb, outboard clutch and a solid design.
@@dynojoemods2764 so the out Board clutch is better for milling. Is the clutch the same design as the 562?
@@Kolsch221
Outboard helps keep the heat away from the bearings. Similar, but larger than the 562
How much fuel does a ported saw burn vs stock?
Is it true it burns ; double the fuel vs stock saw?
I wouldn't say double the fuel. More than stock? I'm sure they do. Some models are harder on fuel than others. Most of the time the increased speed/production off sets the fuel usage.
