| contd :- -3- We attach a chart giving power curves of the SS.{S. Smith} compared with the xxxxxx average Phantom. These are the usual dynamometer figures which are taken. With the cutout open we obtain 104 HP. at 2230 r.p.m. Rear Wheel Carrier. We have now got cars fitted up with the dummy hub type of rear wheel carrier. This appears to function satisfactorily and will be fitted to the next car to go to France. Hs.{Lord Ernest Hives - Chair} | ||
