| X788 24.10.34 Report of Test carried out on Bentley Small Bore Induction Pipe to EX.14528. The purpose of the test was to determine whether this induction pipe would affect the maximum speed of the car, and was carried out at Brooklands. The car (3-B-IV) was fitted with a standard induction system and several laps of the track were completed at maximum speed. The standard induction pipe was then removed and the above-mentioned small bore induction pipe was fitted, and the laps at maximum speed were repeated. The lap times were carefully noted in each case and the average time for each test and corresponding speed was calculated. These were as follows :- Lap Time Lap Speed Standard Ind. Pipe 116.4 secs. 85.6 M.P.H. Small Bore Pipe EX.14528. 116.5 secs. 85.6 M.P.H. NOTE: These tests were run with cut-out open and no fan fitted. Conclusions. Above figures indicate that the small bore induction pipe to EX.14528 has no appreciable effect on the maximum speed of the car. Hs{Lord Ernest Hives - Chair}/C.S.Steadman. | ||
