As I predicted, all the noobs who thought the turbos would sound like vacuum cleaners on racecars ended up wrong. Test-bed recordings never sound like the real thing when it's in action. You really only needed to go back to the (awesome-sounding) 80s cars to get a good idea what they would sound like. Don't know if this is already posted, but a recording of the new Ferrari turbo put in the LaFerrari chassis: To me, that's a kickass sound, and it will sound even more awesome when the throttles are wide open in race trim. I immediately like it better than the 2.4L V8s.
