With reference to the attached dynamometer curve, we do not think that this should have been sent through without some comment on the peculiar behaviour of B.60 when fitted with an exhaust system, i.e., in a case like this it is best to get the unit on the Test Bed to check any peculiarity, and then send both power curves through as a combined report. Will you please arrange, in future, for Swinden to be responsible for all dynamometer horse-power curves, so that we may get a consistent set of losses applied to all curves.
