Just to add a little more info on the Twintake sound:
I find that if you consciously listen you'll hear a fairly constant Darth Vader breathing (as in the vid but quieter) and only hear the additional sounds according to your use of throttle. So, you can actually play it to hear as you want, not forgetting of course that as you are playing it via your right foot the car will respond accordingly!
As someone who is used to listening and mixing recorded music tracks within a song, I feel that the mix balance is on the sweet spot - At least it is on my car.
