no but it looks COOL!!!!!!!!!!!!!!

it's a 'sliding vane' type air displacer more than a compressor,not as efficient as modern screw types that are common nowadays.
i expect the bore dimension and surface to be critical as this is where the vanes seal against to create 'boost',any excess wear could make for more expense to rectify it.he doesn't show the inside.

'$1700 buy it now' price,mmm :-/


ps,may be too small for a 2500 if you're thinking of buyng.

it is for a mk3 1300 1969.

I've never heard of anybody actully getting one to work correctly.  Only ones I see now are on Show cars.  A lot of these were sold for VWs over here in the 60s.

I could be wrong, but I don't remember ever hearing of a Judson kit for the Spitfire. The one in the auction is for the TR2-4.

Looked very pretty but not a lot of good and no comparison to a Shorrocks Supercharger.

I did see a pair on a Flat top V8 Pilot motor years ago
