Would this be the pulley bearing going?
It also reminds me of a normal N/A V6 engine noise...like the 4.0L on the Jeeps they had for so long...just kind of a normal drivetrain noise. Unfortunately, on the SRT-6 it detracts from the beautiful SC whine and the exhaust note...
Any ideas? Is there a normal light flutter in the engine noise?
Satellite,
I know EXACTLY what sound you are talking about, and I have been asking the same question to a lot of different people. It seems more pronounced when the RPMs are low and you press the gas 1/4 to 3/4 of the way without downshifting.
Every time I've asked, people look at me like I'm crazy. I think it's just the natural sound of the V6, more specifically the FUEL INJECTORS. My SRT6 is still stock, and I hear it.
It annoys me, because it sounds like something is messed up. If you find anything, let me know.
EDIT: One more thing, I noticed that the fluttering becomes more frequent (gets faster and faster) as the RPMs increase, up to the point where the engine noise from the higher RPMs cancels out the fluttering and you can't hear it anymore. I hear it the most when I'm passing someone without pressing the gas much.
