Hi everybody,

im looking into ways to supercharge my mk1 850 but would like to use a period piece of kit...

first of all most of you are going to think "huh supercharge an 850? why, just throw it out" but no, i need to keep the original engine, mostly cause a supercharged 850 would be fun and different, but also for legal purposes...

anyway, i've looked into the infamous Shorrock superchargers and read A LOT of mixed reviews, most of them saying they were usually missing a thousand parts or were worn out, and in any case were not worth anything compared to turbos etc etc.. Then I read a few positive accounts of the beast and this got me looking for one. Well there arent any available to begin with, and when one of them is, it is either missing major parts indeed, or simply require you to go rob a bank on your way to pick it up...
so unless a case of huge luck (finding one buried in a sealed box in a field or something) Shorrock is out of the question...

So what other superchargers were attached to minis back in the day? I know that VWs were "often" equipped with Judson superchargers, and have found a few articles here and there that say those were seen on Sprites and other A-series associates, but I couldn't find anything about a judson supercharged mini... does anyone know if this is possible (bonnet clearance-wise, power-ratios etc etc)??
Were there other brands back in the late '60s-'70s that equipped 850 minis?

thanks for your insight..

Shorrock supercharger (Model C75B) is the only one I am aware of. Im sure there are others though.

Edit, you had already done what I suggested.

What do you mean rich, that's cheap for a Shorrock.

Thanks man,
im not feeling too rich, but I have sent an email just in case I decide I MUST have it...

I;ve got a supercharging book at home and in it there are a few A-Series's with them on but most look like inline ones as they are on the back of the engine. One name I can remember from it is Scot Chargers and most of the pics were the traditional roots type with inlet at top, outlet at bottom.

Thanks for the info...

I did look up S.Co.T blowers a while back but couldnt really find any info on their small displacement chargers (ideally 750cc in my case).. most of the ones that anyone refers to are destined to ford flathead engines in hotrods... I have seen mention of small blowers used on Abarth cars back in the day so I might have to keep digging... The company also goes by the name Italmeccanica if anyone else is interested...

if it's not too much to ask, could you give your book another look when you get the chance, just to see if any other names come up? it'd be great help, thanks..

One of the reasons I went for the Toyota sc12, it was as close to a shorrock as I could get without it being an old pile of expensive scrap.
Good luck with the search will be a great build.
