| To E.{Mr Elliott - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X7771. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/ADL2.5.32. POWER OUTPUT - PHANTOM II. X.7771. X.7080. We attach curves of the power output of the Phantom II with various carburetters, which may be of use to you in testing the correct size of instrument for J.3. These curves are also interesting as showing the loss in the silencer. The loss between open exhaust and cut out open is about 10 H.P.
