When we carried out comparative tests with the R.R. and Delage for braking, the wheels were locked for most of the test on the R.R. and the tyres were scraping alongte road. On the other hand we have got to admit that the Delage brakes, as they are, would not stand up to the rigorous treatment we expect our brakes to stand. / The car on the road was very nice to drive as long as the egine was kept running fast but if one tried to creep along on top gear the carburation was bade because immediately one tried to accelerate the engine would cut-out. The Vacuum Feed for the petrol supply was used - it was made by "Weyman" Paris. We found, however, onthe dynamometer that it would not supply sufficient petrol at full throttle as we had to run it on pressure feed. Hs.{Lord Ernest Hives - Chair} | ||
