Why have so many superchargers been removed....

While we're talking about superchargers, I have a couple of questions. By the way, when I say "oil" i really mean ATF.

Can you overfill the supercharger oil? If you can, and you do, what will happen?

Would it be possible to build some type of auxiliary oil chamber that feeds oil into the supercharger?

Sure, Jerry; you can fill it to the top of the filler tube if you want to.

What will then happen is this: The excess oil will immediately work it's way past the input shaft "piston rings" seal and become part of the "air" being blown into the carburetor...kind of a pressurized top oiler, you might say. It will really make an oily mess in short order, and cause the engine to emit clouds of blue smoke like an oil-burner (which it in effect became) until the excess is relieved.

In other words, don't do it because it will make a mess.

You can build anything you want to increase capacity, like circulating the supercharger oil through an auxillary cooler, for example. Just be sure the design is such that gravity permits no more oil to get in the supercharger than it would otherwise have in it.

Jim Pepper would likely have more to say on this, but he's not on the forum. Drop him an e-mail through his e-mail addy in The Co-Operator if you'd like further information. BP

At least the supercharger was left in the trunk in some cases.

My dad bought two cars without a supercharger. The story was the same. "It started to make noise, and the nice mechanic took it off."

I guess that's why there are so many "loose" ones around still.

Actually, like the good sleuth that you are, BP, if you search the forum member list until you get to jpepper, you will find him listed as a moderator with 5 posts in the last two years and an email availability there as well. Almost as tough to find as the right Avanti powered numbers!

All of you that took your superchargers off, I will provide storage
for any of them under the hood of my Avanti.

Your Avanti doesn't mind if it has a McCulloch on it, eh [?] [?] [?]
(I think that's what this post is about...)

lookin' for some too...

Anybody got the bits and pieces laying around to install a McCulloch VS57 on a Stude V8?

Sounded like it was either, but boost is boost. I considered a turbo
also, but a Snail would be best. It will prolly stay N/A though.

There are a lot of screw type modern Cobra ones turning up cheap these
days, but withouth EFI I dont see how they could work on a Stude V8.

No need to build it, Paxton made one. It was a oil cooler that picked up ATF from the dipstick, pumped it through a cooler and back. It kept about a quart of ATF in circulation.

FWIW, The Eaton supercharger uses a rear inlet. Magnusson is selling lots of Eaton supercharger street rod kits. The only difference is that one has a vertical U-base for a top-mounted Holley. Wouldn't be that difficult to fab a J or U-shaped adapter to mount for a carb to sit over where the C/K air cleaner sat and it would fit under a Stude hood.

I've got a NOS Eaton on the shelf I had planned to put on my truck. However, that project is getting a Packard V8 this spring, so maybe I'll build a spec engine with the Eaton.

But isnt the Eaton designed to only move air, not an air/fuel mixture?
I wonder if that would cause any issues. I believe that the setup has
injectors after the blower, near the intake valves.

Hi, Tom,

All I know is Hot Rod Magazine is full of articles about using the Eaton/Magnusson with a Holley on top.

Many years ago, one of SDC's foremost supercharger experts was John Erb, an engineer by trade. I believe John was the first to come up with a computer milled impeller for more boost, and he rebuilt many Paxton and McCulloch blowers over the years (he still may be at it). After several blower rebuilds, he told me the following: Many collector cars with McCulloch/Paxton blowers are not driven regularly. During weeks or months of sitting, the lubricant drains off the balls and out of the pump, thus requiring the pump to re-prime and get lubricant to the balls when the engine is started. During the few seconds this (plus starter motor operation) takes, the balls can get hot spots which can cause trouble in the future.

The way to deal with this is to shut off the engine after running it 15-20 seconds. This primes the blower oiling system and lets those hot spots cool. After 5 minutes or so, the car can be started and driven with confidence that the blower internals are well-lubricated. I've owned many supercharged Studes, and I adopted this procedure over 20 years ago and have not had a blower failure since. The Plain Brown Wrapper always gets this treatment, and in spite of over 350 hard quarter mile runs without rebuild, the blower is still fine.

Comes on this engine :



Hmmmmm .. interesting ... something like this?

PS :

What supercharger? Where?

ford yblocks used the same type of system,paxton-mcculloch,f-code 312's. they also used a four barrel(high top holley which had a small base and the floats on top of the carb.same used on earlier y blocks)a bonnet covered the top half of the carb.later the paxton supercharger was a dealer installed opt.on the gt-350 shelby's 289's
