36 HP Judson Complete Kit This is a restored 36 HP VW Judson Supercharger Kit VW-I..  The generator pulley half is reproduced in aluminum where the original is a stamped steel. A 28PCI Carb is stock for the 36 HP Use Stock Solex #120 or #122.5 main jet ( the original might  be 117.5). There is a spring to put into the fuel pump.  I guess at high speeds the fuel pump must not have kept upwith the stock spring. This blower is usually stamped VWI and has the double belt pulley. Belt tension is adjusted by the  number of gaskets placed between the blower and intake.

56 Ghia engine without Judson Here I put the stock air cleaner on, the standard Bosch coil, standard fuel line, and standard distributor (I had a Bosch 010 distributor on in the Judson photos, no vacuum advance).
Judson 36 hp blower tag On my restored Judson here is what the tag looks like. On it is stamped VWI.
36 VS 40 HP air cleaners Sown here is a 36 HP Judons air cleaner on the left with a 40 HP air cleaner on the right. The 40 hp air cleaner used part of the original VW air cleaner. The original air cleaner snout  was cut off and attached to the Judson air cleaner to provide preheat to the carb. Also, the 40 hp unit has a pipe (not shown here) to connect the engine oil breather pipe from the oil filler stand.

40 HP original Judson Belt NOS 40 hp Judson belt with Judson Logo on it!!!! The Judson Belt is a "Gates 8210" for 36 and 40 HP. I have not verified this so if someone else knows different please let me know.
Old VS New Oilers The old oilers had a Judson red decal placed on them. Shown  on the left is the NOS oiler from the 40 HP kit. The original  Marvel decal was a water transfer decal where the new ones (on the right) is a paper decal. New oilers are available from Marvel for about $90 USD. Note that the original oiler had a safty wire that ran down under the bottle and the pickup tube was longer with a mesh screen on the bottom of it.
