| Hs. {Lord Ernest Hives - Chair} from R. {Sir Henry Royce} +4474 R2/M16.10.28. IMPROVED ACCELERATION. X.1725 X.4550 X.4474 X.523 We are considering 4 ways of meeting the increased acceleration problem with cars, such as :- For ease of { 1. Delavaud free running back axle. getting on { 2. The free wheel side shaft. to 3rd. gear. { 3. An epicycloidal .7 reduction with smaller gearbox. 50% increased { 4. A supercharger. engine torque I would like to fit all 4 so that we could choose.
