    Jee Richie, don't you ever sleep?

    That, my boy, is what you need if your running 18psi and over. It's the second clutch that is actually on the supercharger shaft. The hose is an oil feed to the rear of the shaft into a third bearing (but I'm not sure if it's bush or bearing rollers with this system).

    Nice!

    Pricey but that is the cost of reliable speed.

    Combine this with engine internals, Gary's valvetrain, a really big intercooler, an skm (which appeared on the catalog as well) and a big mother wheel (try the H1 so I can pinch your log file off you) and your ready to go and see what else breaks, lol.

    But still doesn't have ball bearings instead of bush bearings.

    See what happens with other suppliers.

    Not sure I'd be willing to bet a grand on it after reading this:

    One thing for you to keep in mind. This Yamaha supercharger spins 3 times as fast as the Sea Doo supercharger. Those SD clutch washers are barely adequate for the big boost superchargers we're running in the seadoo's. Now, use the same washers on a supercharger spinning 3 times the speed and you will wear them out in a hurry

    Thanks for that MJ.

    I guess one thing to consider is that the SC shaft clutch (in combination with the sprage clutch) isn't working 100% of the time like the Seadoo (at slippage I mean). Plus the load for slippage is been shared between the 2 clutches.

    Good concept but I still stand by the theory that roller bearings like Arts SC'er is "best practice".

    Either way it's nice to see some of squirrells showing up in public at last.

    Good point...just don't want to drop that much coin without hearing more results from people who've tried it.

    Are those ET roller bearings available yet? I've been checking their site & only see the grooved bushings listed.

    Your dead right Squrtn, if a bearing lets go it would not be nice. There is some containing/cage washers involved in the design to lessen the risk but at these speeds anything could happen.
