Stihl Ms881s More power than stock!

Finally here. A Pair of Stihl Ms 881 chainsaws pully ported hit the dyno.
On this video will be a quick teardown, full machine work, squishband and base. Port layout, porting, and reassembly. Then they get on the dyno.
See just how much more power can be found from the most powerful production saw already. Tree service, Fallers, Loggers, Arborist can all use some more power!
Stick around, and let me know what you think.

Paveen that’s what I’m saying also! He does it the right way…or basically the way that I’m now going to aspire to be able to provide a client. The clean and concise before and after data showing the gains made over the RPM range is very professional… he’s definitely one of the most professional porter’s that I’ve been able to see. I’m definitely convinced that providing the dyno information for your clients is a huge part of doing this business properly and professionally. There’s a lot of us guys who can get gains from an engine…this guy can include your printed out document showing your power curve … high lighting your gains on paper on a graph!!! Dyno Joe is my new porter hero!! 😂😂😂😂. He also doesn’t go way overboard ripping the exhaust port out without any intake enlargement like several popular guys do… in my exhaust most exhaust ports are too big to start and definitely don’t need to get enlarged more…! 😂😂😂😂. Saw one of those oem 288’s that you sent over… very neat!!!

Don't speed them up brother, your explanations are part of what makes the video better. If anything I say slow down and share as much information as you can. At least that's what I like. Keep up the great work!

[@DaveyBlue32]

I’m with you Will… I want all the information that I can get. They tell these guys to make short videos to hold peoples attention but it kinda seems to me that the chainsaw world guys don’t fit that mold…if they like how a guy teaches and shows his work we’ll watch everything to the end to see what tips and tricks we can learn. I also love to find a great guy to watch do tear downs …because if I’ve got to rebuild a model that I’m not familiar with…I can watch him tear down a saw and repeat his procedures and save myself a lot of time and effort! 👍😁

[@GripFreak]

Outstanding work sir! As an Echo repair specialist I can state with certainy that even though this is a Stihl saw you have a solid understanding of every aspect of two stroke theory and operation not to mention your experience is very obvious. There's another channel (Tinmans) that is a cool channel but he is more along the lines of having fun by experimenting BUT he has made inaccurate statements and claims. You are in a class by yourself sir! There's a Chinese proverb that states, "without no data your chatter don't matter". This is where you shine! You have the data to back your claims. I would even go as far as saying that your work could be classified as a scientific setting like in a research facility. Would love to hear your backstory and your experience. Keep up the outstanding work and thanks for sharing! Your skill level and understanding is on another level. ✌

I guessed 100hp, wow, closer than I thought. Jokes aside, having the dyno is a Godsend man, the numbers don’t lie. And when you’re gaining 1.5+ cutting torque, that’s money well spent for this tree company. It’ll save them time and money. It’s an investment!

Thank you for the feed back. I am still trying to learn video/lighting/editing. I plan to step up those areas each time. Trying to gather all the lighting and film gear still.

[@dynojoemods2764]

Thank you I think the owners should be happy. I try to build solid everyday saws for my customers.

[@DaveyBlue32]

@@dynojoemods2764 I was really inspecting your porting work in these couple of videos. I know that you’re very conscious about the saw’s longevity being that we are building serious work saw’s here that need to start and idle perfectly all day every day firstly and get a decent power gain without sacrificing longevity. I live the way that you’re careful with your exhaust port window’s and that you don’t blow them out too far. I see a lot of porter’s who expand their exhaust ports a little too much…I haven’t seen any real gains from that so I’m usually good with the exhaust port volume… I compare the intake volume and the exhaust volume and take it from there. Of all the porting work I’ve seen done over the past 10 years if I was going to pay someone else to do port work on one of my saw’s I’d be sending them to you. Your grinding is solid and good quality and you have the dyno to show your before and after data…it’s not “it feels stronger” there’s cold hard facts involved. I’ve got a couple saw’s that I’d like to get put on the old dyno myself at some point…. I’m seriously thinking about trying that tachometer….

[@Parkerpalmer987]

That was amazing! I wouldn’t ever need a saw like those. But I still had fun learning from you! Your explanations with data are remarkable. Thanks for all the effort and time you put into this, and for sharing it with us🙏. I’ve got the itch to port my saws now!

[@dynojoemods2764]

Thank you. Feel free to reach out "before" you get in over your head porting. Little things can go a long way. Muffler mod, gasket delete, and a little bit of widening is a great first step.

[@Akkillies]

To answer your question about speeding it up during indicating, I'm hoping you make a lot more videos, you could make a dedicated video for some of the lengthy setups like indicating and tear down and when it gets to the time laps you could add a link if anyone wants to see the detailed version. Just a thought, love the content though.

[@JoshNoss]

Wow the stock numbers on the 881 (120cc I believe) are nearly the same HP wise and identical torque wise to the 92cc 592xp stock as far as the peak numbers go. The 592 is pretty hot from the factory though so I doubt you can gain much from porting one of them

[@em4703]

Great video. Also, regarding Dominator. Not a fan. If you cut in even slightly humid conditions, its inevitable to get crank rust after awhile since this thing is one of the few oils with literally ZERO rust inhibitors. Every time I opened a saw that used this for over a year or so had rusted crank, and not just spots here and there, the entire thing was brown. Other builders confirm similar things on arboristsite.

[@dynojoemods2764]

Thank you I will have to keep an eye on that. I've used it the last 3 years in Michigan we get pretty humid. Have not seen any rust. But I will keep a look out for it. Maybe they changed the formula, or something to do with ethanol in the fuel.

Does it also increase fuel consumption or does the saw just get more efficient by porting it? Great explanations, very interesting, btw!

[@dynojoemods2764]

Thank you A little bit of both. Power takes fuel to make. Stock does a good job retaining the excess inside. Once modified efficiency goes up to make power from the same displacement. But I'm not sure how much fuel is also wasted doing so. Once i hear back from the owners I will know for sure some models are harder on fuel after mods, but also make more power and production too. I would say 90% use more fuel than stock. Most love the extra power, before ever mentioning the amount of fuel used. Sorry hope that makes some sense

Being you just put these together, I'm assuming both saws will wake up a little once those rings seat and they start getting broken in?
