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.

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.
