Step by step sequence, detailing the progressive strip of the Lancia/Fiat 'Volumex supercharger, the 'Roots' type blower used on the Lancia Beta Vx and Fiat Argenta/Spider Vx.

If you ever buy a Vx - send the blower to me for overhaul, don't try and do it yourself, this is definitely one area that requires my specialist experience. I know 'how and why' and I won't keep you waiting for weeks. These things are 26+ years old and if you say 'it sounds OK' - you might just end up with a junk blower.

I am going to have a major gripe now!
Watch out Lancia Fiat owners! There have been no replacement OE parts - gears, rotors, casings - available for these units almost since they were ever first introduced in the early 70's. Surprised? Well, they were built at Abarth and not many - I reckon just enough for the production run of cars and possibly no more than that. I have NEVER seen a new one for sale.

These blowers are super-popular for racing on vintage cars like MGs because they look just like a prewar blower. Ho ho. Unfortunately mostly they get run on amateurish crank-nose driven methanol powered instalations that lead to the total destruction the blower (and often the engine too), so they are getting very rare.
If they ever bothered to call me first I could at least tell them how to array the inlet setup and blower drive even if I don't know the first thing about methanol.
