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

SGS 1-26A with Cummins Turbo Diesel - but not necessarily in that

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. ;-)
