Ev.{Ivan Evernden - coachwork} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}19/KT.11.12.33. x7771 We have now taken some power curves with the engine which we propose to fit the the Vulture. This is the 8 litre engine of 6/1 c.r. The high compression head happened to be fitted with large inlet valves, these do not give us any appreciable gain. It will be observed that the R.R. carburetter used is the latest large pattern to L.C.3432 and gives us a gain in power over the present standard carburetter - the present 5.25/1 c.r. engine gives about 165 B.H.P.
