Hi....I just got a Judson supercharger , I was wondering which motors it will fit on ? I think it was made for a Bug-eye. Anyone use one of these ?
I only have the manifold and blower , would like to know size of lower pulley and which carb it used.
Also need to buy a Marvel Mystery oiler.
Congratulations on your find Chris,
Judson manufactured aftermarket supercharger kits for many cars in the 1960's. These included the VW Beetle, Mercedes 190SL, Corvair, Volvo, Renault Dauphine, TR3, MG TD/TF, MGA and of course the SPRITE! The Sprite kit was offered as early as 1960. This is according to dated advertising literature that I've been able to locate. The good news is that a Sprite kit will fit a 948, 1098 or 1275. the only difference between them being in the diameter of the drive pulley and the jet size of the carburetor.
The original kit was developed for the 948cc engine (Bugeye). All Sprite kits used a Holley single barrel down draft carburetor (Model number 2042). This carburetor can be found on 6-cylinder Fords built in the mid to late 1950's. The Marvel oiler for the Bugeye installation was located on top of the driver's footwell between the brake/clutch pedal box and the outside of the footwell. The reservoir was a 2-quart, metal canister.
The introduction of the MKII Sprite required that the oiler be moved from the top of the footwell to the driver's side inner wheel well. This was due to the fact that the bonnet/fender design had changed and one could no longer access the filler cap! With the introduction of the MKII kit, the Marvel oiler was changed from a 2-quart metal reservoir to a 1-quart glass jar. Keep in mind that the MKII Sprite still had a 948cc engine in it. Later MKII's (AN7's) as well as MKIII's (AN8's)had 1098cc engines. The supercharger worked on these as well as MKIV 1275cc engined cars. The change to the larger engine capacities required that the diameter of the supercharger drive pulley be modified to maintain sufficient boost pressure. The diameter was reduced to increase the rotational speed of the supercharger. This resulted in an increase of fuel and air being delivered to the combustion chamber. The jet in the carburetor was changed on the larger displacement installations as well.
Contact George Folchi (860) 355-2807, 58 Merryall Road, New Milford, CT 06776. He rebuilds and remanufactures parts for Judson Superchargers as a side business. He rebuilt both of my 948cc kits. He did a fantastic job. He should have the pulley you're looking for. With any luck, he may have an oiler for you too.
Date: Sat, 03 Jan 1998 02:12:39 -0500I have one. Check out my web page at http://web.starlinx.com/dhedin/car.htm. You will find quite a bit of info there.
This same supercharger was also used on VW's (with different manifold) Do a web search for Judson Supercharger and you will find a few references.
The pulley that goes on the crank is the same size as the one on the supercharger. I had to have one machined. If you need a diagram of what it should look like email me.
The carb is a single barrel Holley that was common on 4-6 cylinder GM products of the early sixties. I have successfully adapted a 1 3/4 S.U. to my supercharger.
The Marvel Mystery Co. is still in business and you can order the oiler new I think they still sell it in J.C. Whitney. If not, I have the address somewhere, email me.
