@3:30 "I didn't grow up using computers . . . " @Tinman's Saws - I don't think you entirely grew up at all. That's why I love watching your channel! Stay healthy my friend, and send my love to the Tin Lady and to the Min-Tin. Much respect.
Long time viewer first time commenter 😂 bloody love ya stuff mate! Been fixing up an old 038 magnum and your 038 playlist helped the whole way through mate! Think I watched the whole lot 3x over 😂 cheers for making quality and informative vids 😎🤙🏾 love from Australia 🇦🇺
Great video Tinman. The oops factor is always there when you're doing something new. That was hilarious. Keep working on it and I'm sure you will get it right. I certainly would look at getting a couple of those pipes.
Tinman, if you are interested, I can cut you some exhaust flanges. I am an automotive performance tech and master fabricator, but I also love saws. I would be honored to supply you with some of your most common flanges, no cost, to reduce the time it takes you to test different pipe designs. Long time fan.
Haha love that oops moment haha reminded me of last year the first time I pulled the muffler off my craftsman and A.D.D took over and I really really needed to know what a saw sounds like with no muffler at all hahaha even a lil 40cc craftsman sounds insane 😅 and you can see the combustions happening lol pretty neat for a few seconds followed by a half hour of just giggling like an idiot
I’ve tested many pipes and with the stock can and a single tube pipe seems to give 8-10% over bone stock. The Rowdy pipes I’m building now (similar to the Bearclaw original design) give a noticeable increase over the pipe / can design and absolutely annihilate the stock muffler. Only 2 drawbacks are increased fuel usage and loud (but not any louder than a straight shot or a bark box). If I burn an extra $1 worth of gas I’d say it is well worth it for the increased production and enjoyment (snappier throttle / way more torque). A good set of earplugs or muff is definitely in order. I find that the output is deeper and more throaty with no high pitched sound like the others
@@justinweaver8787 I’d say from seat of the pants it’ll give 5+% over a factory dual port which gives about 7-8% over the stock. Again I don’t have a Dyno to give precise numbers but I wood say 12% over stock peak torque. Way better throttle response and low-end grunt - only videoed the 272xp so some saws may gain more or less … the epa friendly saws may not pickup as much performance as an older non - stratos saw simply because of the design but there are other flow tricks you can use on the intake side to enhance the performance for sure!
Hey buddy fun stuff right ! Do you have an Ironhorse pipe design . My stock 372 xp loves it . Very simple and very effective. Possibly use a thicker flange you can put a bit more heat into the weld . I used 5mm stainless on the flange and tig welded that sucker . Strong as brother . Keep on keeping on Tinman it’s an interesting journey. 👍🏻🇦🇺
I did one kind of a pipe like this for my 372xp but in stainless steel and oh my God it turns up the saw for way better saw!!!! The saw pulls crazy with it! Nice content! I'm a stainless steel welder and cut some wood for pass the winter warm in my house!
Tinman! Great looking little pipe. Props to your brother's fabricating skills. I would 100% purchase one of these for my 372XPW. Consider me on the pre-order list. Been looking for a "pipe" and no one manufactures/sells them. Take care man, happy cutting!
Cool idea on that pipe! Muffler mods I have done on Husky 372's I found if you aim the exhaust pipe at about a 45 degree angle and up a little you lose some exhaust savaging meaning you lose pull in the cut. I found if you use a stock muffler but use a 3/4 pipe. To encourage exhaust savaging I aim the pipe about a 90 degree angle from the cylinder. It seems to have nice pop at idle better throttle response and better pull in the cut and make the saw run pig rich so have to lean the hi jet out a bit.
Hey Tinman , that pipe added a lot of power! So much power it jumped off. That is just what happen when you are working on that stuff like you said . Keep up the good work!
Couple of things I would like to talk about, first is porting, you can modify the port timing by raising and lowering the top edge of the piston, called a performance piston, Also on a pipe your after a couple things, pipe volume which has to do with the cylinder volume, and then the size of the outlet, remember the biggest thing is you want the pipe to pulse and push back on the exhaust port so intake flow doesn't come pass the cylinder before it's burnt, love your channel and your enthusiasm, stay strong
Testing is exactly that , it sounded great while it was going really notice the difference . I have just got the exact same saw so very interested in this . Love ya vids mate all the way from Aus
My 261 has a nununun when you let off the throttle like a dirt bike, they can be improved on but it's very hard cause they are factory made to be 50cc screamers, bigger saws are all about torque and low end and by porting and piping your making a saw run like your 50cc saw, higher end power but on big cc's
I love experimental small pipes like that!... I have built a few! 372xp mini pipe and some horns for a g660 that have done well! I have some videos on them if you have time check it out brother. Some winners lol some loosers! You are correct... thats power saw building!
Wasn't a total failure, just a bump in the road, we all experience those, but I know you n your bro are going to absorb the bumps and fly over them. Carry On Brothers !
Just a word about test failures... there is no such thing! You had a device failure and you learned a few things along the way. That is exactly how things are on the road to invention. Never stop testing and developing a better pipe! Your work reminds me of work an old friend of mine did in ham radio with tuned cavity filters. They resonate at very narrow but adjustable frequency not unlike what you are doing with that exhaust. I suggest you experiment with a pipe that is way longer than you think you need. Install a disk on a threaded rod such that you can adjust the volume of the cavity in that pipe. That makes effectively a adjustable whistle. You can then tune it to the engine for max performance. Then you will know what size pipe to make. I look forward to your next experiment.
I live in the middle of a wind farm in north east Ohio. It is completely flat here. I understand about the wind. It gets pretty wicked. I have to wind proof everything out here. It does get the fire place choochin good and hot though!
So I have a couple Huskys, my favorite being a 371xp. I'm in Arkansas and cut a lot of hardwood. I'm looking for a bit more snap and power for the longer bars. Sounds like I should start with a muffler mod? Anything else you'd suggest before going into it? Thanks for the show
I about lost it ha ha ha!!! Its all about Form Fit and Function and I give you TinMan an "A" for honesty and a chuckle!!! Next version will be a better "A" ???
I am using the old style 372xp muffler with a 3/4" pipe no top outlet on a 390xp. I have been wanting to experiment with the newer muffler like yours with a 3/4" pipe and run it with the factory top port open and then blocked off with a piece of sheet metal in place of the screen to see if it favors the dual port or not on my stock 372 x-torque. I suspect the top port being open may actually hurt the performance, it would be an easy test with the muffler you have. It would be interesting to test a pipe design like your brothers pipe with a single outlet instead of duals as well, coming out the bar side like the pipe on your stock muffler. I would like to make Ironhorse's basic pipe with a single outlet and try that sometime as well. It would be nice if someone would take the time to perfect a design that works great on a work saw and sell them.
You well like the 372 xp I got the new 2020 372xp x-torq had those 372xp you well love it...I love my 385xp too need few new parts for it 385xp 372xp 365 special my 3 favorite saws
I think a lot of people that mess with pipes on saws don't know a ton about 2 strokes and what the pipe actually does. Not saying that is you. The pipe on a 2 stroke if right is like a perfect tuned music instrument. A 2 stroke pipes operates off of sound. I'm a motorcycle mechanic so love 2 stroke dirt bikes.
Minor set back, no big deal. I also think you need the mounting bracket bolted up to stabilize it more. Look fantastic thou. Nice saw for stock. Great video. TC Mahalo Tinman 🤙🤙🤙
I usually just load the stove and throw about ahalf a cup of used engine oil with a splash of gas on it and light it up . Starts off easy and get the wood ( even if its wet ) going.
Shape and design doesn't really matter when making a custom pipe, the pipe volume and the outlet size is really all that matters, I would not build a twin horn pipe from my knowledge of dirt bike and snowmobile experience but that doesn't mean it won't work, stay strong
I still burn wood as my primary heat source. I have 2 Timberwolves, one with muffler mod by Iowa Performance Saw's and one with Ironhorse style muffler mod. Good stuff.
As a welder fabricator I didn’t realize how much diff a pipe can make. I’ll be def trying things out and ideas you guys have let me know I’ll give it a shot
Spot-on statement about the chainsaws operating temperature. Go to far with compression and machining the saw could exceed that temperature and actually LOSE power. IF that’s the case then what’s the point for an everyday work saw ? For a racer yes 👍… looks like the pipe took a wicked hit when you cut out on that ash round
long time ago the first rocket engineers were literally flying by the seat of their pants. their technical references were zero and development was all trial and error. but they persisted and we wound up on the moon.
That pipe worked great until you Blew it off he saw with all of hat power. Maybe a small bracket on the front to use those lower factory support holes will help
As you said it makes it run lean, you need to make the outlet of your pipe smaller, edit, the smaller outlet will give the exhaust a pulse and push back on the exhaust port, stopping the fresh intake air from flowing out of the saw before the piston comes back up to shut off the port
That was a great friday laugh tinman hahahahah! Having experienced a falling muffler or two myself i laugh with you ❤, i think using the tin wind shield behind the mod modded exh gives a little more support for the flange also
Wow I could hear the difference. Let's get some for the 288 's. Yea I'm thinking a nice pipe & a base gasket delete for the stock 288xp. Put a 32" bar on her w/an Oregon skip chain. Oils well but could use some more ars, pull, you know what I mean. 🙃
ya think soldered copper plumbing fittings would hold up for long as a chainsaw exhaust pipe? cut out an exhaust flange outta 1/8 in. copper plate and start soldering 3/4" fittings?
Hey I’ve been enjoying you and your videos. Looking to get a starter saw. What’s you opinion on saws. Im looking at a echo 590 timber wolf. Do you think that a good stock saw?
That pipe definitely added pull it seemed like! In my mind the Ironhorse pipe design seems like it would work best. I honestly have no clue though. Cant wait to see more of this pipe! Mufflers, Muffler mods, and pipes seemto get overlooked. A lot of guys like to just slap a bark box on or a basic Muffler mod. I think thats leaving a lot of potential on the table.
Tinman that's a great video love seeing when thing go wrong this is real life ! Not glad for the failure glad you didn't cut it out. So I'm looking at piping my 550XP auto tune what do you think about that , do , do not . Have you piped one if so do you have video on it or maybe you know someone that has have
i will say that pipe did seem to add some snap and seemed to pull better. a lot of times I can tell a diff in sound of an engine better in vids than in person
Just wondering if I can change out my sprocket on my 266se to a rim sprocket? I have done it on my 038 stihl , but not sure on this Husky I just picked up for 20 bucks. Thanks Tinman, love your stuff, great information.
Tinman: I NEED TO KNOW IF THERES A CLEARINGHOUSE DATABASE SOURCE FOR THE TIMING ON ALL MAJOR SAWS? Excuse the internet shouting but is the timing peculiar to each saw? That’s counterintuitive
That pipe is obviously a different beast, but what do you think of those bark boxes? I’ve heard you say that the saw needs to scavenge air from the muffler and shouldn’t be expelled too soon. Does a stihl bark box still do a good job of that when it replaces the front muffler cover? I’m wondering if it would be best to have a port on the side of the muffler, not right on the front
and ... yeah, all those little knots ... spruce don't split ... yours or mine (except I have a big ass splitter, and it splits just fine). Great early season wood ... I've been burning junk, a little aspen from the back yard ... but, it burns hot.
