    The early version looks very similar to the Duesenberg/Cord/Auburn gear off crank driven superchargers, the only difference being a 1.5' long shaft heading into the main housing. The boost on those was around 9 lbs at 1500 RPM, but, they had undersquare motors with ungodly low end torque.

    Very cool article!

    Yeah, the Paxton supercharger is like the Cord/Dusie unit

    But the valve on the outboard is not a supercharger - just a timed valve

    You almost have to wonder if Robert McCullough ever knew Fred Duesenburg and had any inspiration from him.....They kind of thought the same way with their designing abilities
