Hi Jim

Strictly speaking a turbocharger is a supercharger since they are both
forced induction systems. As you know the difference is that the turbo' is
driven by the exhaust gasses. It is now generally accepted that
superchargers are the mechanically driven variant and turbochargers are the
gas driven ones.

Probably when the 540 was built ( around the time of Noah and the Ark AIUI )
'TurboSupercharger' was actually the accepted term.

...and then, of course, we have the Lycoming TSIO-540; with the TS
meaning "TurboSupercharged" according to the technical manual.

Sorry, couldn't resist adding to the confusion.

order going down the road. ;-)

In the US, a belt driven compressor is called a "supercharger". In drag
racing its called a "blower", the engine is refered to as a "blown"
engine, cause that's what you end up with. ;-)
