    Curious if anyone has a ballpark guess on the normal gain in cc’s and hp with a woods port? I know there are lots of variables just trying to get a feel for an average gain

    thanks

    There is no gain in CC unless you add stroke to the crank or put on a larger bore cylinder.

    As far as gains go, every model and saw builder is different. Some saws gain 20% and some saws gain 50%.
    50% would be twice as fast, or 1/2 the time to make the same cut as stock
