Inside the MS462C

Thanks and love it! I wonder what that 056 mag 2 could do ported.

Yeah! I was surprised with that fella.

As big as you can go ftw!

From 1/2" to a tad over 3/4" dia

I can't get my head around cutting the section nearest the exhaust. of course you've had it in your hands and I'm looking at pictures on my phone.

Why or how?
Why cause Ferris's was done like that. And at the top it's way narrower than the width of the port.
How. One hand holding muffler the other the dremel. Rounded cylindrical burr and patience. Stainless steel is *s-word to grind.

Seems like that structure around the exhaust port is for rigidity of the muffler and maybe for noise reduction. Just my guess.

Nice job there Vince are you going to keep it stock or get it modified

 

[weedkilla]

Thanks Vince, it was the why I was curious about.

 

[VinceGU05]

Thanks Vince, it was the why I was curious about.

Just another thought. Maybe to change the flow and direction of the gases. Maybe that helps dampen noise without being restrictive.

 

[Mastermind]

oh we ran Masterminds 241 and my stock but with muffler mod 241. same bar and chain which was a brand new loop RS from stihl.

my 241 22.47 Muf mod
Skips 241 17.4 Mastermind ported

That's a big difference.

Skip's MS241 has not been gutted either.

Will see the end results of Steph's first before deciding.

The 462 is done and ready for testing tomorrow! Sorry for the interruption, we had two christian holiday's this week (thanks to martin luther and the all saint's) and understandably, its not a good idea in my local area to start a muffler modded and ported chainsaw on these day's

But tomorrow the time is right! I will go back to my test wood from the beginning. And luckily, another two 462's are on the way to me. So i can test stock vs ported head to head next week in one single video. Maybe i have found some gains, we will see

Oh, and here's a super quick video of the saw from today after re-calibration (new style on MT 2.0! 30 sec on triangle and after that you have to hit full throttle for another 30sec for calibration) with some starting, throttle testing and noodling in old, dry beech wood behind my barn. No real testing but better than nothing

So far i'm really excited with the saw

 

[rocco490]

whats the comp stock and what is it after porting if you cut the base and set squish? timing numbers?

 

[StephK87]

Stock comp was around 160psi. I have to check the comp again, feels like close to 190psi now. Rest will follow tomorrow, i'm not in my shop anymore (at my father's farm house).
