  • 'Gear Drive'-'Ball Drive' Paxton Supercharger

    A few years ago, a Studebaker engine builder put together a prototype 'geardrive' Paxton supercharger. (eliminating the somewhat troublesome 'ball drive') I saw a cutaway of this hybrid blower, and it looked like He may have used an automatic transmission planetary drive element for the needed increase in impeller speed. Anyone know any more about this?....Or tried modifying a Paxton in this way?

    I don't know if Paxton or someone else made them, but I saw the working unit and the cutaway in Solanki's garage a few years ago. I spun the pulley on it and the amount of friction was very, very little. A neat blower for sure.

      Turned with very little friction huh? That sounds really good. Any chance You were able to inspect it's lubrication system? Have any pics of it? Thanks

        No automatic would have a 5:1 step up gear.

        FWIW, a friend of mine in the import supercharger business has spent a small fortune and ten years trying to develop a planetary drive. He's never been able to make it work, even on the small scale for sub-2-liter engines.

          I don't have any pics, and I didn't look at it too close. It was one of those, "Oh, that's cool" things.

            Certainly not a 'backyard project'...but if something like this could actually be made to work....it sure would give 'new life' to a lot of burnt out blowers!!

              This supercharger cutaway has been around for some time, and info about it is available from Nash Solanki's website.
              I've seen it, fondled it, and looked closely at it. It is a nice piece and makes you wonder 'what if'???

                  Nash has been around, and active with Studebaker performance for years.
                  The quality of his work is great.
                  He just doesn't frequent forums because if the nitpicking.

                      FWIW, I think one of the reasons McCullough used the ball drive on the original superchargers was to avoid the known problems of high-speed gear trains. Gears have always been very costly parts to make. Every time the engine changes RPM significantly, you are going to have reversing torque loading on those gears, so they bounce from one side to the other of the slot between the mating gear teeth, causing impact wear.

                          Paxton made a couple dozen, actually. They were sold under the SN2000 label (and further confused with the GSS label) which went back to a balldrive configuration after they figured out they were already behind and had to go to the NOVI gear drive to stay up with the competition. Kind of confusing, unless you know the serial numbers to look for.

                            I've heard of the Paxton SN2000.....but had no idea that it was a gear drive unit. That's interesting! Maybe one will turn up on e-bay.

                              The overwhelming percentage of SC's labelled as SN2000's are balldrives. There is a huge bounty on the gear drive units and most sold on EBay have no idea which they have. Dig for the serial number changeover to ferret out the good ones.
