Judson Has Arrived!
Hi Guys,
I bought a Judson from the US a while ago and it just arrived, one bit of advice, if ordering parts from US make sure the seller marks the value as
under $1000 INCLUDING shipping, I just went over and had to pay gst + processing fee. Fun.
Here are a few pics...
 
And the inside, I'm not so happy now, needs vanes, bearings, seals and possibly needs the rotor to be machined to make the slots square.
Not too bad I guess and better than running it without knowing! I'll do the measure up over the weekend and try and fit it under the lid of the ghia
without cutting.

The bottle writing says "mason' which is an american bottle company for pickles, mayos etc. I'll keep an eye out for an original one in the
meantime.
If anyone is interested I'll take a few pics of the rebuild and fitting, this is where I'm trying to squeeze it in without cutting the decklid.
If anyone knows where I can find/have made a slimline airfilter or carb top, I only have around 25mm from the top of the carb to the bottom of the
drip tray of the decklid.
Cheers,
Kevin

contact
I'd look at machining you rotor.
Best to contact George as he can supply you vanes etc.
I think any judson these days would need to have this sort of work done.

I've been talking to George and he told me the rotor is within reasonable tolerances, just needs bearings, blades etc which was a relief. He is
quite busy doing rebuilds and couldn't get onto it for a year so I have ordered the new parts and hope to get them before Christmas so I can do the
rebuild over the break.
I've gone for a slightly overdriven main pulley, 6" compared to the standard 5.4", this is only just under 9% but will hopefully match the 1500
more closely. George is also machining a belt tensioner for me to help with any belt slipping.
I'm planning to strip the Judson completely this weekend and knock the bearings out. Pics to come.

The parts for the Judson arrived today from George Folchi in the US. The main pulley has a slight overdrive to match the 1500 and the smaller pulley
is a belt tensioner. This didn't come on the 40hp Judson but makes adjusting the tension much easier.
Work is a bit quiet until next week so I will try and get a start on the rebuild tomorrow.

I wonder if its worth looking at updating the supercharger a little using some more modern concepts like internal coatings.
If competition coatings could coat the inside of the supercharger housing with teflon, you might then be able to run castor oil to lubricate it. From
what i've read its the least combustable and will have the least effect on lowering the effectiive octane rating/causing detonation, compared to the
normal oil that was used with them which i've heard does limit their true potential.

I dont think the Teflon coating would be an advantage as the vanes / blades need to bed into the internal wall of the housing to make them work
efficiently and together with the oil make a near complete seal when overhauling a housing is advisable to have it honed out similar to a engine
piston and barrel set up
the teflon would reduce the friction of this function and maybe not make a seal
Mine has run great for years no probs
The normal oil is a straight 10 grade which does 3 things
lubricates the vanes / blade in the rotor slot
acts as a seal with the vane to the housing wall
acts as a upper cylinder lubricate
I use ATF fluid which is also a 10 grade fluid
it burns with a sllight white smoke Its cheap and easy to get compared to straight 10 grade or castor oil

Hi Guys,
George did a test with teflon blades a while ago and they only lasted about 10 minutes before breaking, I think they need to be very stiff but kind of
soft as vw54 mentioned to 'bed in'. They are talking about using a material called Torlon(?) but it is quite expensive at the moment.
As mactaylor said, these things are super simple, and the way prices are going at the moment someone will do a homage version soon for sure!
I'm sure George wouldn't mind me popping up his price list...
Support bracket - $12.00
Main Jet - $16.00
Vane set - $85.00
Bearing and seal set - $60.00
Gaskets (3) - $6.00
Tensioner - $125.00
If you have time he also offers a full rebuild of the blower, oiler, filter etc etc for $500 but he is flat out at the moment.
He finished the parts on New Years Day and they arrived yesterday all for a fixed $30 delivery fee.
Cheers,
Kevin

thanks Fillet
what size is stamped on the main jet or is it blank
I have listen to all sorts of thinking regarding the blowers and mterials etc etc
In the end they cost more than an arm n a leg
Best off keeping the simple way of doing things you dont get problems that way mine has been running for ages

Hi Guys,
Had a flatout week and only managed to strip it down and clean. Will try and get it back together next week. The new jet does not have a size stamped
into it but I will email George to ask.
Phat Bug would you have a pic of a type 3 carb top or any dimensions? (mainly the thickness) as I am trying to get as stock a look as possible.
Cheers,
Kevin

Finally got some time to work on the Judson, replaced all the seals & bearings, repainted the body and gave the rotor a bit of a clean up. I'll
pop it back together over the weekend and then start the install as soon as I can track down a slim enough air filter, does anyone have any ideas/pics
or dimensions?
Cheers,
Kev

what engine r u fitting the blower to and what carby
the Type 3 carby is a good idea but i dont think it will fit to a Beetle carby It has a bolt fitting attached to the top that allows the air filter
to be fitted You may have to get something made from steel tubing that takes the air entry tube down n away from the carby top to then allow the
filtting of a normal or judson air filter
