| YE230 HS.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} R2/10.3.31. C. to - SO. MOR. BY.{R.W. Bailey - Chief Engineer} JAPAN 1. - EXHAUST SYSTEM. The Silver Ghost had the best system, and we have never found anything better. The two sets of 3 cylinders were kept separate for some distance. It will need the exhaust ports 2 and 1. thus Inlets will be 1. 3. 6. 7. 10. 12. Exhaust " " 2. 4. 5. 8. 9. 11. with the exhaust heat passages from 4. and 5. and 8 and 9-groups. It is understood that the carburetter must have the following items. (1) Jet control. (2) Starter enricner (not strangler.) (3) Pump accelerator. We cannot buy this combination, and this our reason for mixing, and will leave us better than competitors. R.{Sir Henry Royce} | ||
