    Info for guys running over 18 psi with stock superchargers.

    Hi All,

    It would appear that if your running over 18 psi the thrust plate on the supercharger (stock or the R&D replacement) will die on you sooner rather than later.

    So, I'm dropping back to the 18 pound race ET wheel with the slipping clutch shaft and three roller bearings. Thanks to Art for a good system and all the hard work.

    Dean

    PS Art's new billett chargers run a different thrust control system.

    Good info Dean. Do you plan on running one of Art's new Superchargers?

    Yes but in a little while when funding improves. In the meantime I'll just be a fly on the wall.

    They look awesome and I hope they work really well. Pretty sure Art wouldn't invest time and money into something he wasn't sure would deliver. It's just a good hunk of change for someone like me to plop down who really doesn't have the intention of running higher than about 14 pounds of boost. I keep holding out for a clutch fix still since Yamaha's attempt didn't go so well.

    Art's billets are expensive but so is a new yami charger. But it does go a very long way to fixing the clutch issue, be it you have to check the slip point from time to time.

    Someone who wanted a fix for the clutch can go two ways.

    1. The rotax clutch. But if you wanta go higher up in mods (over 18psi) then you'll end up with the same issues as other's, thrust plate. bush bearings, etc.
    But if your staying under the 18 pound mark then it's a good cheaper option.

    2. Art's billett with a suitable wheel for your setup (stock internals <15pound). Just keep your old charger for when you upgrade to the 2.2 litre yami sho model when their released, or sell it.

    It's just what I see happening at my end atm.

    PS I told Art I'm out of "the race" but I just can't help myself, lol.

    Where is this info coming from? What Yamaha needs is a PUMP.
