| 600 FOR LOG BOOK. 3.1.38. 24.G.VI. Run week-ending Monday, January 3rd. The suspension as at present arranged is a great improvement over anything we have previously brought on the Wraith. The car seemed to be reasonably controllable in the hard position without being uncomfortable and reasonably soft in the easy ride position. The engine period came up once for a quarter of an hour, but after that desisted. We should like the car to be run on Prices' Motorine C. or XL., and see what effect this has on the crankshaft period. We experienced the first brake squeaks we have had on Thermoid lining on this car. They were high-pitched squeaks, and took place after the brakes had been used severely. The starting up was satisfactory. The engine was quiet when idling. The car was not too noisy over setts. Wind noises are still exceedingly bad on this car, and an attempt should be made to improve them. We should also like to try a front roll rod. Rm.{William Robotham - Chief Engineer} | ||
