With all due respect guys, why would anyone want to hear turbines again? They're as dull sounding as the oil burners. Jet turbines have ruined the sport of unlimited hydroplane racing. They used to have the throaty roar of RR Merlins,, now just a montone whine.
Personally I always loved the bark & crackle of a DFV, the scream of a Ferrari, or Alfa flat 12, or the bellow of a unlimited boost turbo offy, but those days are long gone.

I love the sounds of which you speak.
But I am a race fan ('have participated in my small way..) and have an appreciation for whatever works, The Howmet was not a major effort. The Indycars ('67 and '68) were.
'Understanding the "excitement" of the sound of race cars; I am more interested in the tech...
'Nuff said.
