| To Sg.{Arthur F. Sidgreaves - MD} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} c. to Wor.{Arthur Wormald - General Works Manager} c. to E.{Mr Elliott - Chief Engineer} c. to By.{R.W. Bailey - Chief Engineer} c. to Hn.{F. C. Honeyman - Retail orders} x209* Supercharger on the Bentley. We have now been running the Graham supercharger on the test bed for some little time. The main object of these experiments is to provide data for the design of supercharger now being prepared for the high power head unit. The main points in question are silence of operation, slow running, durability and efficiency. The Graham-Paige will shortly have completed 10,000 miles, we shall then strip this supercharger which will give us a line on durability. There are quite a number of problems in connection with the other points. It will probably be several months before the experiment is completed. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
