| X 204 X 4550 E.{Mr Elliott - Chief Engineer} } FROM R.{Sir Henry Royce} HS.{Lord Ernest Hives - Chair} } R2/M4.10.32. C. to SG.{Arthur F. Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} BY.{R.W. Bailey - Chief Engineer} BENSPORT ENGINE - SUPERCHARGER. It will be remembered that nearly 12 months ago we set out with the engine fitted with supercharger in the front. We suggested trying it separately on the test bed to prove what we wanted, and that superchargers should be tried of the Rootes and Powerplus pattern. With this part of the programme we do not seem to have made sufficiently rapid progress. The job wants shaking up to enable us to get along a little quicker, as the final drawings of the chassis are awaiting the dimensions of the blower, which is close to the radiator, radiator fixing, and the front axle. We understood from E.{Mr Elliott - Chief Engineer} yesterday on the 'phone that the Amherst-Villiers people had wound up their interest in the Roots type of supercharger for car engines, and were not in a position to offer anything. As one would imagine this sets free Messrs. David Brown & Co. Ltd., of Huddersfield to supply us with either a complete blower, or to produce the rotors of the exact profile used in the Villiers blower, which was reported by the Bentley engineers to have given very little trouble. It would be worth while for HS.{Lord Ernest Hives - Chair} or R.{Sir Henry Royce} to put someone on this matter as a full time job, as it is hanging EV{Ivan Evernden - coachwork}'s drawing of the complete chassis.
