    Nitrous won't work on a Phantom II with mag limbs, only straight and elite.

    Don't know what weight arrows you are shooting but I think you're dreaming. I just converted one of my Phantom IIs over to Straight Nitrous from Mag Fuzion and I only expect to gain 5fps if anything.
    With my heavy 500gr-ish arrows that might end up 245fps but more likely 240fps, that's at 29" and 65lbs.

    I don't have my notebook with me but I think it's something like 10fps per inch. 1-2fps per 5 grains of arrow weight. 2-3fps per pound of draw weight.
    I guess the bow to be 310-315IBO. That would put you at around 222fps with 225gr arrows.

    I need more info and maybe we can get you there. What is the intended purpose of the bow? hunting, target shooting, be specific. What release are you shooting, who's strings are on the bow, what arrrows, what rest, what vanes on the arrows, how long have you been shooting, how much do you practice? All of this matters !!!!

    Now that I've had time to get mine tune and chrono'ed I can say what I'm getting.

    28 1/2" draw, shoot through, B cams, 475gr arrows, about 66lbs draw.
    20 strand 452x string, 14 strand cables, minimal serving, string leeches, Surz-a-peep, string loop.
    247fps.

    That is a pretty heavy arrow for 66lbs. The bow might actually feel better with a lighter arrow. What limbs are you using ? Who built your strings?

    Those are my light overdraw arrows
    I'm planning on removing the overdraw and going with 520gr arrows eventually.
    Wouldn't lighter arrows allow more noise and more shock?
    Besides that, I'm all about hunting. I care more about momentum than I do about speed. I'm getting much better with shooting the X system. If I can get where I can shorten the stabilizer before hunting season it will go hunting with me.

    Straight limbs.
    I built the strings (and the bow for that matter).
