    When I got into the ported saws in 07. Cost was $100-$150 from the reputable builders. Todays cost would be hard to for me to justify when I had so many back in the day.
    Personally learn to do porting yourself. I tried and never could to get to run like the ones I paid for. But back then it was so affordable to just pay for the top notch stuff. I lost all interest in doing myself since I knew who to contact for the good stuff back then.

    Lets say you have a 261 stihl and have it ported. Would it have as much power as a 361 stihl after the porting was done. I have never ran a ported saw so just trying to get an idea from saws that I have run.

    I've toyed with the idea of having a saw ported for a long time - but, I always come back to how my saws perform stock. I am a firewood cutter only, so not extra $ to make with less time (although time is always money they say). You can see the saws I own below - with a good sharp chain, they cut plenty fast for me - having one ported would only be for fun - and I have enough fun already - I'll put my money somewhere else for now. But......I still want one! Cheers!

    Here is a dyno graph of one of my MS261Cs.

    The green line is a MS361 ported by another guy.

    From the 361 graph, I take it that the 361 responds well to porting?

    Guess not as well as the 261cm... I really need to pick one of those up "for my 'Pop".

    The 361 you did for Bowtie was a good one.

    The 261 graphs show a nearly a 25% increase in HP . . . I would say that means the 261 responds quite well to porting.

    Randy, have you seen any dyno data on one of your 361s? The one shown above from 'another guy' doesn't seem to have a very big bump in HP over what they're rated at stock.

    I've got a 361 awaiting a port job and I live right around the corner from Chad! For the sake of science, I think it needs to move up to next on you backlog. You know, for science and dynos;-) JK, I'll be waiting like everyone else...
