i dont think the audio is editted...my car really sounds like that...but you wont hear much blow off...the turbo does whistle like crazy...but theres some major lag
Just opinions from a guy who owns a video production company... here are some things that help support my idea.
Regarless of how far away the TT GT gets, the engine hum and turbo whistle never change in volume or tone. If the audio was shot from the chase car, it would get more quiet as the TT GT moved away. The tone of the exhaust would also change as the rcording angle changed and as you intruduce the windshield, blocking the direct audio path.
There is music playing in the background. If you listen to the video, it almost sounds like someone using a hammer on a piece of metal, but it is music. Well, the right front window of the chase car is all the way down (tint on windshield vs the lack of tint on the door window). Why can we hear he exhaust and turbos of the TT GT and the light volume of the music, but there is NO sound from wind blowing into the car?
Something that makes me think it could be a complete fake, the spooling sound matches the car movement, but not the engine RPM. You hear the engine RPMs build slowly and steady through the whole video, but the spool sound is all over the place.
I have owned several turbo charged vehicles. I know you can be at full boost without being at WOT due to electronic or vacuum controlled pressure control systems, but there
is a relationship between RPM's and boost that seemed a bit off in that video.
