X5770 It is proposed to continue the test on the 20 HP. car to complete the 10,000 miles. We are also preparing a modified cyl. head to give a lower compression ratio to send out to this car. Tests are also being made in Derby on 12-G-4 car to see whether the existing engine mounting can be attached to the frame more rigidly in front so as to reduce the oscillations on the front of the car. Tests on the 20 HP. car will continue with the object of adopting the improvements as soon as possible. We attach report on the above car after 7500 miles. Hs.{Lord Ernest Hives - Chair} | ||
