Is there a dealer fitted supercharger/turbo


Hello team,

Does anyone have any information/proof that Judson superchargers or a turbo installation were offered by the VW dealer as an optional upgrade for performance.......
I have been searching and everything I find point's a finger towards aftermarket suppliers for the vw community ....

would appreciate any documentation/pictures proving otherwise

Cheers Anthony

Volkswagen were very much against any performance upgrades to there stock motors as they considered it shorted the life of their engines. Shit it took them 20+ yrs to accept multigrade oils for their engines. All hot up gear was by unsanctioned aftermarket suppliers. My2c

That's exactly what I'm finding ,
I did read that one dealer did sell judsons for a few months but pressure to cancel there franchise stopped them selling/offering anything further.....

No, Australian Volkswagen agents never fitted Judson superchargers. They would have voided VW's Australian warranty. Likewise, Australian dealers did not fit big bore kits, twin carb kits or any other aftermarket parts. Dealers were only authorised to fit approved Volkswagen accessories, as listed in the Accessories booklet - radios, mudflaps, carpets, trim, roof racks, spot lamps, seat covers, fire extinguishers etc.

However Judsons were available from various aftermarket suppliers. This is a typical ad from 1960 - Ron Ward Motors was not a Volkswagen dealer. McCallums were the VW dealer at Strathfield.

Turbos were the same. They were not even available until the 1970s. The Australian company Rymec used to supply turbo kits for '76-'79 Golfs, but not Beetles.

currently if you fit a period correct Judson or equivalent to your vw it makes the car void under state and fedral modification of VSI8 and VSB14 and 20% increase in output requiring an engineers.
So im trying find proof of dealership installations (worldwide) to meet the requirements of the above.

Before I outlay the dollars for the equipment, Thanks for your help so far gent's appreciate it

I've got an old article on Empi/shorrock superchargers and they are good for 80% increase according to that.
They claim 72hp from a bone stock 40hp 1200.

That's interesting, it doesn't comply if you fit one NOW according to that document - I guess you could argue for ones where they were fitted in the 60s/70s etc before the regulation act came out... as it states -
"the requirements of this information sheet are not retrospective. This means that, in general, modifications undertaken in accordance with the version of VSI8 current at the time of modification is carried out will remain acceptable into the future unless a future version of VSI 8 specifically states otherwise"

I've never tested mine on a dyno to see if it does actually give over 20% output... the advertisements say up to 50% but not sure if that's real world! I always thought they were offered by dealers but it does make sense that Volkswagen wouldn't be keen on that.

Regulations have changed so "now" a current car or oldie has to comply to the regulations.
You can reach the 20% power figure with N/a and no one would be the wiser but as soon as your forced induction with turbo or supercharger you must jump through hoops with documentation to keep it legal

If you can prove it was a dealership option then yes you can fit a supercharger or similar with an accredited dyno sheet or factory specs showing no more than 20% power and it avoids an engineer certificate.........This is why im chasing any documented information

many thanks anthony

What are costs and how hard is it to get engineer to sign off? Anyone done it? It's not like it's massive power.. mine will just keep up with my cousins 1600 as long as there's no hills involved haha.

Like I do with all my modified cars, newer, larger and forced induction engines. I get them engineered VASS in Victoria, and then the certificate allows full rego, and insurance. Personally I don't bother with up to 19.99% power increase. Just go for what you really want, do it legally, and enjoy.

it's about 600-1000 dollars for the engineers, brake test, plus the dyno output from certified set of rollers.......

Hellbus "Where / whom do you get your certification done"....?

Im not trying to dodge a bullet ,but I would like to keep the 40hp and the truth is you can double even tripple your torque and stay within the 20% with the correct setup which is what im wanting to do but under the fedral law "it need's to be a manufacture option" so once again Im chasing proof of dealer option's
Which means I will consult a engineer today

Another option to keep the 40hp would be dual carb kit - not sure if Wolfsburg west is doing an okrasa kit for the 40hp or not. Only skimmed the regulations but can't really see anything on modifications on adding a carbie apart from something on emissions which due to the age is exempt. It was one I was considering before adding Judson but at that stage there was no feedback on the kit...

ok here's the thing

6.1
fitting replacement , used or recondition engine, exhaust components , induction, in all cases , if the engine is modified such that resulting power increase is greater than 20% in must be certified by vass signatory.

This is the problem if twin carbs were offered by the volkswagon dealer it considered a manufacture option it's ok.......if it wasn't then it's aftermarket and it's not.

I manufacture small turbo kits and supercharger kits for other makes and there all out side this scope and require an engineers due to output.

Im doing a beetle for myself and I'm trying to sail as close to the wind as possible without involving engineers or as stated if I need a vass for 20% why bother just keep going 50,60% as it's the same test's time and piece of paper.

The funny thing is twin carbs are excepted although they fall under the same guidelines , but superchargers and turbos are frowned upon straight away as a no no..... unless you can provide documentation proving "manufactures options" it's hard during registration

Cheers and thakyou fella's I appreciate all the input I will continue to dig the web for something :)

found this on the vw Judson register

The fact that Judson were selling their supercharger kits for the VW through VW of America's official dealership network is a little surprising, given VWs open hostility to any tinkering with their flat 4 engine. It is also surprising that it wasn't until 1960, that VWoA decided to put their foot down; threatening any official VW dealership with the loss of their franchise if they continued selling accessories not sanctioned as official VW accessories. VWoA also reminded dealerships, that fitting a Judson Supercharger to a VW would immediately invalidate their warranty

And also a supplier in Australia brand new vw with blower options........

With forced induction they immediately apply a 1.5 times on the engine capacity. So a 1200cc force inducted is seen as an 1800cc. The $800 I paid for the engineers report is the best investment in regards to my car modifications, as it makes it legal. I have been pulled over in two of my cars at a time when questions were asked about modifications, and having a copy of the report in the glovebox showed what size engine, transmission, wheels, suspension, track width and that it was checked for noise, pollution and braking. I know it is all still correct, so happy days. And yes one of my cars is supercharged, and that is part of the engineers report.

My understanding is 69 and older don't have to comply as they don't fall in to ADR requirement because there were no ADR before 69.

We had this discussion at my car club with the president of the club permit scheme. As the discussion went no engineering cert is needed for 69 and older but RWC is or will be required real soon. That was the best of his understanding but he did say vicroads/rta do need to clarify the rules better as you car get away with heaps on technicalities cos of the way the guidelines are worked.

for example.. We got past easy with a LX Torana that the owners and I converted to a later model holden EFI v8.

We complied to the rules by stating the output was actually less than the A9X high performance v8 option and we used a crate engine with service part number instead of one with an actual engine number. Holden stated that the service number was non car model specific and sold as spare part thus could be used in older models without needing and the gear from "the donor car" nor a cert.

technicalities like this allowed to pass with no engineering cert. Vicroads said it was ok and its done and dusted.

Another mate of mine did the same with his Monaro HQ.

So given the period of the SCs and if your car is before 69 where ADR and before emission existed, I can't see why its can't be approved without engineering cert.

Ern Abbott was NOT a Volkswagen dealer. He was a VW racer of the day and had his own used car sales and service outlet, but he was not a Volkswagen dealer.

The Judson VWs he sold were low-mileage used VWs that were already out of warranty. The equivalent in Sydney was Theo Borrer, a VW racer who had his own workshops and sold Judson kits as well as modifying owners' cars. He was not a VW dealer either.

Judsons were not an authorised Volkswagen accessory in Australia and were not sold or fitted by VW dealers.

Doesn't matter you just need dealer proof worldwide as an option and they were sold in America for a short period as such,

Ern Abbott wasn't a volkswagon dealer it's creating a paper trail That yes the chargers were in austaralia and yes they were sold briefly as a dealer option regardless if they were stopped.......

I have spoken and satisfied the necessary Authorities with the above information cheers for your help chaps

Good news you found what you were looking for! I was curious as I haven't ever been pulled up on it - insurance was no problem to add it on as an option and the police that have pulled my car over just want to check out the semaphores haha.

Have fun with it... mines been on my daily driver for a few years now and the 36er is now much more capable to keep up with newer cars. If you need any parts George Folchi in the states is very easy to deal with. Marvel mystery oil can also be sourced from a few aviation supply shops but there are a few other options you can use.

Anthony,

any chance you can supply a copy of the dealership paperwork or advert, with the Supercharger option you are referring to in America.

G'day mate,
go to the Judson register "look" under history find "sales" in the transcript there is a small reference about the dealer in the states.......it's not an advert,
I used it to establish a link (paper trail) to an Australian supplier , who offered it on top of the new purchase for 99.10 pounds, although not an official vw dealer the cars were new and it's on our shores.

Not to different than HDT for holden or FPV for ford.......this then allows you to fit the charger under the regulations by using its age ,adr , emission and then using the wording eg "replica" if needed .

Hope this helps

Any one wanting more info might try a search for "Judson Supercharger" at The Samba.com
There seems to be lots of threads and discussions about these which might be helpful.

I just find it funny that even with 50% + more power and how light they were, the cars were stupidly slow by todays standard for a Daihatsu or something slow sold these days lol.


but back then I guess that was fast.
