COPIES TO: (RCJ) (BJ) (WOR{Arthur Wormald - General Works Manager}) (By) E Da{Bernard Day - Chassis Design} (OY) (RG{Mr Rowledge}) Expl. No. 3579 3503 REF. Hs{Lord Ernest Hives - Chair}1/LGS.12.25. OBJECT OF TEST. ✓ Alternative scheme to suction Autovac. TESTER. A.J.Lidsey CONDITIONS. Road and dynamometer tests on 5-EX - Silver Ghost car. SUMMARY OF TEST. We have run the car for 2000 to 3000 miles with the standard pressure pump converted into a vacuum pump and have had no difficulty with the petrol feed. It will be seen from the attached report that the petrol supply is sufficient without using the reserve for practically all the demands of the engine. Hs.{Lord Ernest Hives - Chair} | ||
