I have noticed that at "idle" if you turn the fan off (to make things a bit quieter) I can here a whine. It sounds a bit like and electric fuel pump running (but it isn't that). If you engage "drive" as the engine revs drop the pitch changes to a lower tone too. Does anyone have any idea if this is the same for all SRT-6's or if I have something going wrong with mine ?

Performance is still great and it uses no Oil at all.
Power steering fluid is at the correct level.
nothing appears to be rubbing on the "drive belt"

I have only noticed this since I had my Steering box replaced...but for all I know it may have been there before, but just didn't notice it as I had a few issues after the steering box was replace with air in the system with resulted in low steering fluid levels for a couple of days. I took the car back and they topped it up again. All the air is out now and everything is just fine other than this noise.

I can hear the noise with the radio on low and the fan on "2", but I think it is due to me becoming "tuned" into it all the time now and it is driving me to distraction as to weather it is "normal" or not... !!!
