PIPE VS MUFFLER REAL WORLD GAINS?

Testing the ms 170 pipe vs a stock muffler. Does an expansion chamber work on a chainsaw?

More 170 testing please. I'm as curious as you are Joe on what will hold up or fail. Plus, small saws need love too. 😅

[@treewisemenllc7281]

I love the little 170s. This is awesome!

[@PurpleNovember]

I like the experimenting with the saws. Interesting seeing what does what to the saws.

[@IndianaDoug]

I ended up bringing the timing back a bit on mine, seemed to take away rpm but add torque. Mine is also the older style 170 though.

[@R_Kyllonen]

Great video. It’s really nice to follow along with the small steps of a build and see what she does. 👍

[@BuckYaSaws]

Love the sound of a piped saw on a Sunday morning!

[@toddzilla6491]

Great video!! Love the real world testing backed up by the dyno. Thanks👍

[@Houseworksaws]

Meanwhile mine is sitting over here smiling with a hole drilled in it’s muffler lol 😆… Honestly I was surprised how well it runs after all the work I did to it. Cool video Joe, Great content

[@coxsaws]

Rock, on with that little wood cutting machine. Give it an alcohol carb and some pipe and see if you get it into the 5.5 range

[@johnclarke8180]

Well done Joe, I still find it hard to believe that the stock saw made the most amount of torque. HP gains were definitely impressive. Thanks for sharing.

[@Super-Dave-Outdoors]

It made the most TQ but it was under 8000rpm in a range that you typically wont cut in.

[@Bigcheif360]

Like these dyno sessions trying different things then putting them to the wood. That 170 is holding on well for turning those kind of numbers.

[@Hambonebodi]

She sings a beautiful tune with that pipe ❤😂😂😂

[@tedneitzel]

Good stuff Joe! Looks like its figured out now well done!

[@dynojoemods2764]

It is getting closer

[@steezin_4no_reazon]

I would def buy one of these pipe for my 170 just for the exhaust note alone

[@markcdeyoung3118]

-Grind the cylinder to match the pipe man You're gettin' her down to a science 😎👍

[@dynojoemods2764]

It is all a science. Since I'm not rushing to make an event I can take the time to do incremental changes to see the effect.

[@joederringer6716]

@@dynojoemods2764 Have you ever done a test with different fuels? Chickanic did a video on different store bought fuels and some kind of hurt performance and wouldn’t make the rpm of others. If you haven’t would you make a video please?

[@ragercrepair9301]

If it's faster it's worth it! I would like to see alcohol and nitrous! Good video!

[@lifebehindtheaxe3835]

Imagine this saw in white pine same size with a race chain...

[@thomaslindroos1667]

When I go wide open throttle on my 272 it fourstrokes just like it should but after a second it starts cleaning up and then revs higher until I let go of the throttle because I'm afraid it'll blow up. To me this sounds like a vacuum leak that causes a lean condition but that mfr DOES NOT LEAK! I have pressure/vac tested it to some crazy values and its airtight. This is tested with 2 different carbs.

[@dynojoemods2764]

Check the fuel lines, that they are solid no holes or dont get pinched while running

[@thomaslindroos1667]

@@dynojoemods2764 that could be, there is a small possibility that the fuel line is 35 years old

[@frankz1125]

Sounds much better, Its almost a race saw. LOL . Cheers

[@michaelmeyers1827]

I’ve been led to believe that 2 cycles always run better with a like back pressure in the muffler

[@Billy-burner]

Back pressure and 2 strokes are words which should never be used in the same sentence.

[@dg9bfc]

Pressing back the fresh air mixture that escaped from exhaust opening with a resonant pipe can give 50%more power.. Like using a turbo

[@yo_marc]

@@dg9bfcnever thought of this until your comment: I wonder if strat saws see the same gains from a pipe as a non-stratified engine might.

[@PurpleNovember]

I’ve had this thought for a while. What would happen with full skip chain and a little lower rakers. Would it hold higher rpms,

[@crperformancetucker5065]

Be cool to see a piped 2511

[@joeracertx]

Very Interesting results. Who made the pipe?

[@dynojoemods2764]

I made the pipe.

[@joeracertx]

@@dynojoemods2764 You did a great job. I watched your pipe fabrication video after I asked this question.

[@10homie]

Hey bro, larger carb u mean drilled main jet hole or another carb?

[@dynojoemods2764]

Carb swap

[@PurpleNovember]

I’m curious about running a pipe on a milling saw.

[@dynojoemods2764]

I just so happened to win a 36" mill setup at sawfest this year. Might need to pipe a 660 and see how it does....

[@scottallpress3818]

Would make sense especially since it won’t be in the way

[@PurpleNovember]

@@dynojoemods2764 Running a pipe should be fine for the engine, right? I’ve heard it’s not good to run ported saws milling because of they can run too hot under a constant load? Could a pipe help a stock saw run cooler? Would a gasket delete with stock port-timing numbers and ignition timing advance be okay with a pipe on a milling saw?

[@PurpleNovember]

@@scottallpress3818 That’s exactly what I was thinking. I’m also wondering if a stock saw would run a little cooler, maybe enough to get away with a gasket delete and timing advance.

[@dynojoemods2764]

@@PurpleNovember with everything and the pipe designed right it could work in theory. But I am not really sure.

[@meskalin64]

How does that tachometer work?

[@mackenziesibley7025]

What carb are you running joe?

[@patthesoundguy]

Is that the stock .043 gauge chain? I wonder if the .050 chain would speed up cut times. I really like those 170s more with the bigger chain

[@dynojoemods2764]

That is a 3/8lp picco. 050 14"

[@patthesoundguy]

@@dynojoemods2764 right on already the bigger chain 👍👍👍

[@joehackett9471]

More better on pipe, me thinks!

[@richhoffman432]

Do you happen to know at what rpm this saw was 2 stroking/4 stroking at?

[@dynojoemods2764]

It was still plenty rich in the 13k range. Even on pipe it wanted to be above 14k before it was sounding good.

[@jamiewykes8585]

what diameter is the cherry you are cutting? I'm trying to gauge performance with my little saws using the cherry I have on hand.

[@dynojoemods2764]

I'd say 10-11" or so.

[@jamiewykes8585]

Thanks, Is that a 14" bar on the ms170?

[@dynojoemods2764]

@@jamiewykes8585 Yes 14"

Just a thought ? what about pipe wrap on that expansion chamber?

Keep sonic what your doing, maybe sometime you could do a video on mixing oils
