| C O P Y. Rm {William Robotham - Chief Engineer} /TAS. {T. Allan Swinden} from Rm. {William Robotham - Chief Engineer} Rm. {William Robotham - Chief Engineer} 10/ML.20.5.40. Here is an alleged B.H.P. curve of the Lagonda we tried the other day. When you have made your comparison on a ton/miles per c.c. basis, compare with the actual, measured acceleration figures; you should then then be able to complete a B.M.E.P. curve which represents what was actually obtained on the car we tried and it would be interesting to see how it compares with the curve I am sending you herewith. Will you please return attached details when you have finished with them. Rm. {William Robotham - Chief Engineer} | ||
