Pretty sure this has already been suggested before, but it would be nice to have these sounds in the game. I mean, just imagine being able to have a car sounding like the BMW M3 from need for speed most wanted and Carbon (Probably not the most realistic of representations but still sounds cool)
As far as I know, these are the two most requested features, regarding audio. I'm sure the devs have something planned, especially since we got turbo sounds a long time ago, so people have been asking for supercharger sounds since then too.
