Jim I was answering Bob's ? about the aircraft engine he read about on the memorial at Pikes Peak.As an aircraft mechanic who has worked on radial and inline engines from that era,I felt qaulified to answer the ? about turbosupers.The answer and definition were aimed at the aircraft engine not at auto engines.The systems on WW2 aircraft use both internal and external superchargers at the same time ,external turbos pressurize the air at altitude,send it through an intercooler to prevent detonation,then it was sent through a pressure-injected carburetor before being sent through another gear driven internal supercharger(usually 2 speed-high blower,low blower) for further compression,then,finally,it was sent to the cylinders.Turbosuperchargers did,in this application, compress the air before the carb.Fighters and bombers were able to reach the high altitudes because they wre equipped with exhaust driven turbosuperchargers.The much smller turbocharger used with modern auto and small general aviation aircraft engines, is an outgrowth of the turbochargers used on diesel trucks.The oldest text I have is 1932,the newest1996,all give the same internal-external definition.BillJ
