Eric Platford - Chief Quality Engineer} PN{Mr Northey} OY RG{Mr Rowledge} WTA MX{John H Maddocks - Chief Proving Officer} Expl. No. REF. Hs{Lord Ernest Hives - Chair}1/LG30.11.25. OBJECT OF TEST. Performance on Brooklands track. TESTER. W. A.{Mr Adams} Robotham. CONDITIONS. 10-EX car - standard engine except for high compression pistons. SUMMARY OF TEST. The results of maximum speed tests show that the only factor worth consideration is wind resistance. We believe we could increase the max. speed by many miles per hour by attention to this point without spoiling the appearance of the car or destroying the efficiency of the wings. Brooklands track is now closed until next Spring. Hs.{Lord Ernest Hives - Chair} | ||
