| -2- Hs {Lord Ernest Hives - Chair} /FD. {Frank Dodd - Bodies} 15/KW.6.4.36. Acceleration tests have also been carried out on Shardlow Rd., and an average figure taken both ways with the following results :- | | 10 - 30 MPH. | 10 - 40 MPH. | 10 - 50 MPH. | 10-60 MPH. | 10-70 MPH. | |---|---|---|---|---|---| | | Secs. | Secs. | Secs. | Secs. | Secs. | | (1) Small Carbs. and small ind. pipe | 7.05 | 10.4 | 13.8 | 18.8 | 23.8 | | (2) Large Carbs. and small ind. pipe | 7.2 | 10.7 | 14.45 | 19.2 | 24.4 | | (3) Large Carbs. and large ind. pipe | 7.6 | 11.0 | 14.5 | 19.4 | 24.7 | Conclusions. As the figures shew, the small carburetters and small induction pipe improve the slow running, and give a slightly increased performance against the larger carburetters, The most noticeable difference being the improved slow running. Attached are time and speeds taken at Brooklands with the 3 systems. Changing the cylinder head and carburetters from 3-B-IV ex B-56-BN {W.O. Bentley / Mr Barrington} shewed a negligible difference.
