    Hehe

    I can see how it addresses the broken shaft and worn bearings issue, but not how it helps the clutch.
    Is it just me or do we seem to always be at least one step behind?

    Great looking piece though. Hopefully this will have a cost advantage over the stock S/C if one gets toasted.

    It has a slipping clutch setup on the shaft. Been working fine for a while. The pain in the arse has been the thrust plate hasn't been able to hack the axlial pressure of 18pounds +. Now the 3 bearings will fix that particular issue.

    You'll still need to do service on the supercharger clutch, ie. retension every now and then and replace when gone. Plus the sprage clutch in the motor is still working, but not as hard. No as much inurtia on the clutch or the teeth.

    The 3 bearings are a plus. I've run them for a while and it takes about 10 seconds for my supercharger to wind down after switch off. A lot less friction than the bush bearings.

    Well done Art, about time you let it off the lead.

    Oh by the way. I think the front housing can accomodate GT35 housings. But I could be wrong on that one.

    I have many customers using the Rotax Racing booster clutch and they swear by it. Just set the slip on the clutch every now and then and it's good to go. Sprag clutch stays safe.

    This is like what I'm doing. But bigger front housing.

    Yup.

    Same concept and using Seapoo parts like they do.

    But I'm not getting into a "who did it first" discussion .

    I was tempted to go the RR system on my backup charger but they didn't have the roller bearings, still the bush bearings.

    Plus the thrust plates gave me grief on anything over 18psi, so I was waiting on this unit for the linear bearings to eliminate the thrust issue.

    I think this is the way forward to 24.

    Edit: I think the RR system is shit hot as well. A hell of a lot cheaper to fit the RR system to your stock supercharger and save the sprage clutches (2010 and 2011), than to pay a mechcanic to pull the motor out and pick stuff out of the sump.

    I check my slip point every 10 hours but I ride like an old grandfather. If your cc racing it'll be more. How much will depend on conditions.

    My focus has been building pressure for river racing but it has had an occassional workout in the surf. So the bearings and thrust plate wear has been my priority. The slipping clutch shaft is an added but very worthwhile bonus. No busted sprages for me..........yet. My clutch is a 7 of 07 vintage.

    The cc/ocean guys from what I've heard are doing well but you need to ask Art about that stuff.

    I'm only going to relate my experiences on the whole concept.

    If I don't get 30 pounds reliabily out of this concept, it'll be back to turbo for me (although I hate the heat issues from turbos).
