- 8 - It has not been possible to obtain successful castings in RR.53 up to the present. Standardisation sheet is to be issued for this. Larger Inlet Valve and High Compression Cylinder Head. It was agreed that a standardisation sheet should be issued for the larger inlet valve and higher compression head as tested on 4-B-IV but it should only be used in special cases where extra performance is required. It was not thought a wise policy to increase power at the expense of roughness. We have no cases of complaints from customers of lack of power or poor performance. We should therefore keep the high compression head with larger inlet valve for special cases only. The Experimental Department will give full particulars of the cylinder head used on this car. Pedals with Moulded Rubbers. These were stated to have been very satisfactory. They were made by the British Goodrich Co. of Burton. It was agreed that these could be standardised and brought on production when convenient. E.{Mr Elliott - Chief Engineer} asked if he could examine the pedals which had completed tests. All Metal Flexible Petrol Pipe. This was reported to be very satisfactory. It was agreed that this could be standardised and brought on production when convenient. It is a much neater looking pipe than the present standard one. Experimental Dept. have two makes of all metal flexible petrol pipe on test and they have undertaken to specify which of the two makes were tested on 4-B-IV. Servo - Floating Fabric Type. It was agreed that this could be standardised and brought on production when convenient. More clearance is required on the outside diameter of the moving plates. BY.{R.W. Bailey - Chief Engineer} undertook to arrange this. Larger Horn Button. It was agreed that this was an advantage and could | ||
