Having reasonable hope of success of either the Roots or Powerplus, I should get the one we could obtain most conveniently and quickly. It would seem that SU. will give all that is wanted. We have put in the largest valves we can, and if on trying these we cannot get the results, it has occurred to me that we might build a little engine more like our aero, with one camshaft, and double valves. They would be quite little, and if of good shape they ought to stand up well, but can we do this if Peregrine is a disappointment. You have the data of what we got through the R.{Sir Henry Royce} engine valves. I assume all these speed cars would run with special fuel. R.{Sir Henry Royce} | ||
