| -2- (5) Compare bonnet temperatures at 40,60 & 80 M.P.H. full throttle with (a) shutter control of water temperature. (b) thermostatic bypass of water temperature. (A handwritten word 'control' is present between lines (a) and (b), and a handwritten '/' is added after 'bypass' in line (b)). (6) Determine extent to which matrix area can be reduced with 58 mm matrix to equal standard matrix - same speeds as (1). (7) Compare induction pipes for lap speeds. ----------------- Hs{Lord Ernest Hives - Chair}/Std. | ||
