| COPY OF R1/M/2.10.25. PHANTOM EXHAUST SYSTEM Referring to your BJ6/H29925, we have a more power ful engine which is exhausting more and hotter gas, and we cannot expect to get it as silent as the Silver Ghost without considerable loss of power, or increasing the capacity of the exhaust system, but we have no room, and cannot afford the extra weight and cost. We have already done much, and have no more time at present. R.{Sir Henry Royce} | ||
