| ORIGINAL. FROM R.{Sir Henry Royce} C. to [REDACTED] HS.{Lord Ernest Hives - Chair} ENGINE VIBRATIONS. It seems pretty universally agreed that with the diamond mounting fitted with torque reaction dampers and soft rubber, and the crankshaft fitted with semi-balance weights, and the thin disc of the flywheel, we can use the 6 cyl. engine of high speed and good output without uncomfortable vibrations being communicated to the bodywork, and this permits us to obtain a considerable step forward in B.P. which will allow the big car in the continental tourer form being a 90 MPH. car, and the 25HP. capable of going well over 70 MPH. with full equipment of splashers etc, and a comfortable body.
