Sorry guys here is a start.The best audio is the last 8-10 seconds as the car moves past the camcorder and back toward the PC Building.Be sure and turn up the volume so you can hear over the wind noise.Of course everytime something is out that I want to shoot as a vid...the wind is blowing 900 MPH right in my face.I know BMW is now on record that the X"M"'s will be powered by tweaked TTV8's.The exhaust note still sounds much higher pitch than the TTV8 in the 50i X6.I'll get better w/ my camcorder.Thanks!
