| X7856 To Hs.{Lord Ernest Hives - Chair} from BJ. Temperature Tests. BJ4/E14/9/27 Brooklands. Your memo. Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/LG12/9/27 is of much interest. As we are now preparing to use Phantom cars with only two shutters instead of four shutters in the bonnet, were tests made to ascertain what was the effect of using only the two back shutters open? Was any test made to show the difference if only the back were open and only the front were open? Under the circumstances such tests should be very interesting. Were any tests made on hills as our complaints of engine overheating chiefly occur on long hill climbs and not at high speeds? Are you able to tell us anything from the Brooklands test as to what is likely to be the effect of doing long hill climbs on top gear for instance when the car is travelling slowly with full throttle? I presume on the Sports car it would be desirable to have ventilators in the scuttle at the sides and top to assist in keeping the driver cool? 10-EX is very hot in the driver's seat, especially with the hood up.
