I did a little search, but didn't come up with what I was looking for. Just picked up this car with a NW CAI, C3 pulley, rear cats removed, and LET tune. Runs hard and strong, but has a funny little flutter/light clicking I presume when the SC engages. I'll hear it at part throttle, but more pronounced at 3/4 or full throttle. 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?



SOUND CLIPS ADDED!!!!!

Windows Up:
SRT-6 flutter (windows up) - SRT-6 noise when under load, windows up, "flutter", also SC whine seems very quiet for NW CAI and C3 pulley.

Windows Down:
SRT-6 flutter (windows down) - windows down, under 40 mph in 2nd gear
