    This morning i was reading @Ryan 's thread about CAR SPEED and STYLE 1959 and in it was an add for OBERHAUSEN superchargers which i'd never heard of before, and i thought. How many super charger manufactures have there been since let's say 1800 to the 1960's. Let's try to keep it period correct, but one's i can think of are.
    GMC
    S.C.o.T ( Italmecnicca)
    Oberhausen
    Latham
    McCulloch
    Wade
    What others am i missing?

    Early Paxton blowers were McCulloch superchargers, they developed their dedicated supercharger division in 1956 and sold it off in 1958.

    Frenzel also produced a very limited number of superchargers for the flathead Ford.

    I can't remember if this is a WADE or Judson. 11182035_818880724867177_8347127431900608570_n.jpg 11196227_818880658200517_3484360914625559807_n.jpg 11168035_955893774441302_1717080376105710452_n.jpg 11169796_955893841107962_3252544508575284363_n.jpg 10405520_818880691533847_2453446434763632601_n.jpg

    It’s a Wade RO34. The angled outlet at the bottom in the pics is actually the inlet in the stock setup, most people machine this bit off and bolt a carb adapter in its place. The blower in the pics is actually set up upside down. It also says Wade on the case.

    I guess if you are starting in the 1800’s then we can include the original rotor type designed and patented by the Roots brothers. Not designed as a supercharger, but rather a blower, it was produced to ventilate mines. The Roots led to other industrial blowers such as the Melee-Dexter that was tried on the Offy four cylinder at Indy, the Schwitzer-Cummins and Gardner-Denver. Some of the industrial blowers were built from cast iron rather than aluminum and were made to move air or even powders, such as flour. In the early days of forced induction hot rodders tried them all at one time or another.

    This is a GMC 4-51 on a 283 in a Corvette, the 4-51 diesels had problems and were soon replaced by the 4-53 series. Chevrolet dyno tested engines set up with these blowers and AFAIK this was the only one installed in an automobile. This is a very nice, clean installation and it wouldn’t surprise me if Duntov was behind this project.

    Wade used the angled inlet to smooth out the air flow pulsing caused by the straight rotors, as compared to the helical rotors in the GMC. The GMC rotors were more costly and complex to machine, but the angled inlet was an ingenious solution to the pulsing problem.

    @Fordors That's why i said 1800 because i know Roots style blowers were designed for ventilating mine shafts back in the day. (Kinda like a Potvin set up) I was also thinking of spliting this topic in two with the two basic types, like the centrifugal (MacCulloch) and Roots (GMC) style. But not the more modern Whipple (screw) type that you'd see on a Top Fuel car.

    AFAIK Potvin did not make blowers, just the hardware to mount them.

    You can add Norman from Australia as Eldred Norman built sliding vane type superchargers for various applications from the mid 60's through the early 70's. A friend of mine had one on his six cylinder Holden and also had the optional clutch that allowed him to drive the car normally aspirated and then turn the blower on when he needed extra power--Yep, just like Mad Max (but for real)
    http://sahistoryhub.com.au/people/eldred-norman
    This article does not touch much on the superchargers but give a good idea of how smart the man was:

    Gary Dyers ended up making blowers, and still does today. Possibly newer than what the OP is looking for.

    The first Dyer sales brochure.

    Gary Dyer introduced his street blower kits in the mid-’70’s initially with 2” Gilmer belt drives and for less common combinations he was modifying aluminum four barrel manifolds.
    His early drives used an aluminum hub for the blower pulley with a saw cut and two 5/16-18 pinch bolts (no key way!) and the snout was a sheet metal fabrication. Connecting the shaft to the blower gear was an OEM forging.

  25. Interesting topic. If everyone can leave the drives for GMC style units out or the various clones all based on the GMC design, whether 6.71 or 6v71 or their derivatives and just keep to unique superchargers, this will be very informative. :)

  27. Someone should add the history Of Robert P. McCulloch. He is famous for superchargers, land develpement and Lake Havasu Az.
