COPY. X 7080. To E.{Mr Elliott - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/AD12.5.32. POWER OUTPUT - PHANTOM 11. X.7771. X.7080. We attach curves of the power output of the Phantom 11 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 HP.
