YouTube - ‪2005 GTP strange noise when reving‬‏
The car is only doing this after taking it for a long drive of at least 50 miles. After starting the car up cold it will not do this and I can drive it around town as much as I want and it'll not do it. In the video I had my wife rev it to maybe 2000 RPMs and no higher. The intake is clamped down tightly in all spots because that's what I thought it was at first.
It doesn't make the noise at idle whatsoever like what cracked flexplates do. I've removed the supercharger belt and checked it out and it still makes the same racket with or without the supercharger running. I've not removed the primary belt though.
Does this sound like a bad tensioner or a water pump to you all?
