| -2- Chassis. (1) Engine mounting with torque reaction dampers on the crankcase and on the front engine mounting so that the best position can be selected. (2) Marston type radiator matrix. (3) Front axle control. (4) Latest type of single valve shock absorber, aluminium cases, fixed loads latest design of split piston. (5) Shortened propeller shaft, balanced 3.00" dia. (6) Servo lined with RAD.13 material. (7) Improved exhaust system reducing the back pressure loss at 4000 R.P.M. from 13 to 5 BHP. (8) Low rating road springs. Initial deflection Front 3.25". Rear 3.875". (9) Pivot lean increased to 4º found necessary to give directional stability. (10) Rear axle with strengthened gears. As the result of running this first car in France, the second car will be built up with the following known requirements and any others that may be found necessary:- (1) Front engine mounting with torque reaction in the correct position. (2) Increased sump cooling. (3) Final camshaft to be determined by bench and road tests in conjunction with the R.R. carburettor and turbulent head. (4) Turbulent head. | ||
