It has been about 10 years since I have torn down and rebuilt saws on a daily basis. Never did any significant mods; only performance tunes. Cylinder and piston rarely.
Somehow I have collected a lot of saws. 14-17 (probably on the higher side after I dig them all out)
Looking for some "pipe" mufflers that are done really well and "actually" produce more HP.
On mods I will open things up a bit; reduce piston weight some, remove any second ring, reduce tension on the remaining ring.
Probably try a couple pipes. Only cut the minimum inside hole in mufflers just for heat escape.
I've already got a proven hp pipe for my 2511 echo.
Want pipes for a 372xt/chin and would like to find some pipes for a few Zenoah/chin 25,38,58cc
Would like to find a pipe for a 6401 Dolmar
Doing squish and piston shave ... opening things up without porting, changing timing.
(More study required)
Probably going to move 3/4 of the saws out so I can build a 372xp Big bore. I already have a Dolmar big bore setup at the ready.
I really like "Ironhorse"; are there any other links or knowledgeable you might recommend? Any ready made pipe mufflers that are not overpriced? I only want more HP and heat dissipation. Anyone able to have an insert-able spark arrestor in their design yet? (On the venturi exit tube transfer from the expansion tube exhaust?)
Looking for pipes pro made after the attached design.
