Another Paxton Supercharger Mockup

When I started screwing the Model A together again as a roadster, I cut out a bracket to bolt a Paxton Supercharger to the 283 in it. I didn’t have the time at the time to finish it up then, but I have to swap radiators and it would be easy to get to the front of it, I decided to play around with it. I needed to figure out some sort of drive setup for the supercharger.

I’d come across a modified McCulloch Supercharger originally from a Kaiser just before, in a box of stuff from an estate sale of a gentleman who had been running it on a Studebaker of some sort back in his younger days. These types of McCulloch superchargers typically have an electric solenoid that controls the amount of pressure the air plenum sees, but this particular supercharger has had the front of the case cut off and what I assume the low boost section removed. I’ll be optimistic and hope it works, but won’t be surprised if it doesn’t!

This is essentially the drive setup I want to go with. These types of superchargers aren’t amazingly efficient, and can be driven by a single V-belt.

The case needs some fore-and-aft support, so I’ll fab up a bracket for that. I need to build an adjustable tensioner for the supercharger, the idler pulley is there and will work just needs something to hold it.

In the above pic you can see the supercharger outlet isn’t exactly lined up with the carb hat. Easy enough to change, I’ve been told once you remove the snout bolts you can rotate the housing to line up with whatever you need to. The carburetor hat is from a mid 50′s McCulloch supercharged Y-block Ford.

We’ll see, but I’m probably not going to have the supercharger running this time around,either. There’s still a bunch of stuff I need to do first, but every little bit I tic off is a little closer to having it on the car.

You can see my bright and shiny new aluminum radiator in the background of this picture!
