Really cool.
The indy has a more F1 vibe to it.
The proto has bit lower vibration.,
The sprint has i think the nicest. I like the idle sound. sounds lazy. I think it fits the dodge.
(terrible descriptions, i know. Don't know much about engines)
I renamed them into separate folders, so I can quickly swap them.
Attached for whoever wants them.
Thanks Zapper for the research. Gives a bit more life to the game,
