OK I'll go, engines and aeroplanes that I have never flown and almost certainly never will..
4 Rolls Royce Olympus (Concorde)
4 Rolls Royce Conways (Model as fitted to the Super VC-10 for the added "crackle")
4 Rolls Royce Merlins (Avro Lancaster)
4 Rolls Royce Griffons (Avro Shackelton)
Almost any large radial engine, but in particular the Bristol Centaurus
Of the aeroplanes that I have flown and still hear almost daily..
The Continental GTSIO 520 M/L (GITSO) as fitted to the Cessna 404. Sounds like a pair of Ferrari engines on each wing
The Continental IO 520 as fitted to the Beech Baron, I love the harsh bark of these engines
Can't say the sound of any modern high bypass jet engines do it for me, although I doff my cap at the designers for their incredible reliability
