Bacon's book has a good explanation, with the math for straight pipes megaphones and double ended chambers. you are on the right path with with using the concept of the pressure wave I am surprised you are still allowed to have a chainsaw in the UK but it looks like you live rural Keep up the good work from an Stihl 066 owner
I am basically a newer subscriber recently and I have seen your dyno which was quite impressive so I expect to look for another one of your videos here shortly showing test results with your muffler mod, isn't it quite interesting as you can alter your designs how you want and test them to find just the right fabrication design that suits your desire. Very good video
Thanks for the kind comment, I'm going to do some more testing on the dyno soon amongst other stuff, including another fast saw build and further exhaust mods and tests, hope you enjoy.
Sounds great I watch dyno Joe, it will be interesting to learn some more about your pipes, its a bit of a dark art building a good pipe that's not a big expansion chamber.
Yes it seems to work well, I'm going to do dyno test soon to see, and I've got a few new ideas to add to my up coming parker 58cc build, haven't done much been building a new garden shed.
Quite a bit. Jetting had to be ajusted to get the best, it had more power, nice and crisp, I'm doing another one soon as I'm in the middle of a simular build but I've got a new design in mind then I'm going to dyno test it with a free flow muffler and then this new one .
@lyf45mo I really don't know, but the fuel system is designed to work on a standard chainsaw, so really I have no idea weather it will be able to re ajust fuelling correctly, I have a sthil ms 362 c which had fuel injection m, tronic, which I do not like as it complicates the engine especially if you want to do power mods, so I've modified mine back to normal carburettor as it's better for modifications.

Hi Henry yes there's no rules on chainsaws here, it's just a tool, thanks for the positive comments, I just love experimenting power mods.
someone that talks slow, about time, explains it , i thank you
Thank you Butch, I'm glad you enjoyed the video.
Really like your videos. Not that I have anywhere near the motivation that you have

How to build a short expansion chamber that looks like a standard muffler
Works very well gives good power and allows the saw to be used as normal.
Thanks for sharing
My pleasure
Very nice. Subbed based on just what you've said on this 1 video. Most exhaust mods are based on more noise equals more better.
Interesting stuff...🤔👍🏻

Thank you for making this video
Thanks glad to help.
Hi Mark I’ve been playing around with pipes over the last few weeks and I found your ideas to be very interesting. Thank you.
Let me know how you get on, with what you do please pal , I'm interested.
@@marklutwyche8578 I’ve got quite a few videos up about pipes now and I’ve sent a couple of my pipes to Dyno Joe for testing.
Sounds great I watch dyno Joe, it will be interesting to learn some more about your pipes, its a bit of a dark art building a good pipe that's not a big expansion chamber.
Have you considered you may be back-stuffing with gas pressure rather than sonic waves? Very interesting stuff. Thank you for sharing.
Thank you, have a look at the how to build a short expansion chamber one, I think you will find it interesting.
That's how I build mine..

How much did it effect your jetting!
Quite a bit. Jetting had to be ajusted to get the best, it had more power, nice and crisp, I'm doing another one soon as I'm in the middle of a simular build but I've got a new design in mind then I'm going to dyno test it with a free flow muffler and then this new one .
@@marklutwyche8578 Will the new Huskys with fuel injection take care of that?

i think i could help you alot with this design if you let me. just sayin
Very kind, but for me the joy of getting more power from a chainsaw is all about thinking of ideas and making or modifying myself, it's my hobby.
@@marklutwyche8578 if you dont mind id like to work on this as a 2 cylinder variation for a personal vehicle.
