| Contd. -3- HSG/T4.10.22. The cutout arranged in a similar manner as the present 40/50 gives us maximum power and maximum noise with the cutout open, and the present standard of silence when it is shut. The disadvantage is that the exhaust gasses are liable to get into the body if the car is luffed up with the cutout open. It may be considered, however, that this is the least of the evils because it is no trouble to close the cutout. Attached herewith particulars of HP. obtained. Hs.{Lord Ernest Hives - Chair} | ||
