Mazdaspeed 6 Noise??? Help

[Tubescorcher]

Hey Guys,
It's been really cold here in South New Jersey the past week with temps down in the single digits at night. Anyway, today I started my Mazdaspeed 6 and let it warm up. I started driving, Stopped to make a right turn. Proceeded when clear. Only giving car about 1/2 throttle just engaging a little boost. I heard a loud pop sound then a clanking sound that followed. The sound speeds up with engine rmp's. or should I say stays consistant with rpms. Faster the R's the faster the clicking noise. I can't imagine what it could be. Car is not smoking. It sounds like a bad valve. Noise is loudest from behind the intercooler near the turbo. Any help would be greatly appreciated!!!!! I searched youtube and the forums to hear my specific noise and came up empty. It's kinda like the VVT noise but mine seems louder. Here is the link to the video with the sound.

You sure that isn't the VVT? That's pretty much the same sound I heard before having the VVT and Timing belt TSB taken care of. Only difference is that my sound went away after about 15 seconds.
