Subject: Re: Supercharger
Marshall superchargers were certainly used in the early 1930s by MG, Frazer Nash and others. At this time the company were called Marshall Drew and Co. Marshall cabin blowers seem to have been the main business under the Marshall Godfrey name post war but this association ended and by the mid/late 1950s the name was Marshall-Nordec and they were making bolt on performance kits for MGs and other BMC cars like the A35.
Marshall Cabin blowers were developed for cabin pressurisation during the early 1930s and were used by the Air Ministry during WWII. There is an article on Marshall Cabin Blowers from Flight Magazine around 1942 and this can be found via google as can copies of Air Ministry Manuals on the Marshall
I think all readers will be interested in the development and trials of a twin screw blower. There has often been comments by 2 Litre owners that it would be interesting to see what could be achieved by gearing the standard blowers to give greater boost. The car recently sold by Richard Edmunds Auctions was Marshall blown through a Jones downdraft cylinder head. I am told it was very effective.
