CAST IRON ENGINES - INSTALLATION. We are anxious that the design work for installing a cast iron engine in the proto-type frame should be completed as soon as possible. We suggest that the best way of dealing with this job is, first of all, to complete the engine mounting drawings for the six and eight cylinder. This could then be followed by drawings of the six-cylinder fitted with Bentley type Induction System, and having a single exhaust system as at present fitted on 9.B.V. Enough layout work has been done to enable us to experiment with the Duplex Exhaust System, but it is no good trying to draw it accurately, because no one knows what this will be finally. Having completed the installation of the Six, we should like the controls and the exhaust systems done on the Eight. It is almost certain that the Eight will stick to the Duplex Stromberg, which is the Buick induction arrangement, and we should like it coupled with a single exhaust system, the expansion box being of Buick dimensions. Ald.{F. Allwood - Experimental Design} has particulars of the 1938 Buick Exhaust System, and we expect to have purchased a 1939 car within the next few days. As soon as the installation of the Eight cylinder is reasonably complete, and it is not possible to be too meticulous over this at the moment in view of the fact that modifications are to bound to arise as experimental development proceeds, we should like the Wraith replacement with the Eight cylinder engine to be left handed. The best way to do this appears to us to leave the engine as it is, left-hand the controls and the pedals, and make provision for the exhaust pipe which now will come the pedal side of the chassis, missing these obstructions. To complete the left-handed scheme, it will, of course, be necessary to deal with the change speed lever, and we have in mind that this will go on the column. | ||
