Subject: Re: Supercharger
I am not an expert on superchargers but have a 2 Litre on which I am seeking to install a supercharger. I commenced this project having discovered my engine had a crank that would take the counterbalance weights so I rebuilt it to supercharged specification. My intention is to install a Marshall Rootes type blower of which there are 3 or 4 cars so converted in the club. Whilst I have all the parts I am still some way from completing the project. The Marshall blower installation is a major project which requires a lot of skilled engineering support, but there are those who argue that it has advantages over the vane type blowers such as the Cozette. For example the Rootes type blower does not wear out vanes (of course it has none) or casing (like the Cozette) and has a full lubrication system, so does not, I believe, need engine oil added to the petrol. That said, there are those who believe the vane type blowers (Cozette and Zoller) give superior performance.

My advice would be to seek to get your Cozette blower rebuilt rather than pursue an alternative. If it is original to the car it will maintain the cars provenance and value. You Could contact Derek Chinn Precision Engineering who are experienced in the Cozette.

I know it is expensive to have a blower rebuilt but occasional large bills are the something I have grown to accept with our thoroughbred cars.
