| -3- never anything but quiet and soft from the driver's seat. The heat was never objectionable, and I think that however quiet a Rolls-Royce engine may be there should be an air space introduced between the front compartment and the engine compartment, both to insulate sound and heat. It would seem to cost comparatively little if incorporated in the design, and I am sure that the results would be well worth the effort." Would appreciate your comments. OY. | ||
