whining noise ?

[trendkilllx]

I am the original owner of a 03 cobra with 72k miles and noticed for the last year or so there is a whining noise that seems to change pitch with the engine rpms, everything seems to work and runs great. Has stock blower and still stock pulley, original alt and I changed out both drive belts about 6 months ago. Any ideas?epper:

It's supposed to whine

yep, unfortunately the whine is not the normal supercharger under boost! also sounds a bit different. It seems to be easy to hear at idle or low throttle with the engine unloaded, thinking might be an idler, alternator ect but difficult to tell.
