EXHAUST SYSTEM TESTS - CONT'D.{John DeLooze - Company Secretary} The real object is what improvement can be effected on the 3 port system and its comparisons with a 4 port system in order to give head design for B.111. The few suggestions as laid down do not, of course, cover the possibility of what can be done and necessitate thorough investigation. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} | ||
