I was revving my car up the other day because a friend wanted to hear my exhaust, and when it's going down in rpm's I can hear something whining. I popped the hood and had him rev it up, but I didn't hear anything from the engine bay. Is it just my gears even though the car is in neutral? I have the stock 3.55's. Thanks!

Not the gears. Is it a whistle or a whine type noise? Could be the clutch...

when the car is in neutral, the items
that are spinning are:

crankshaft
pilot bearing
slave cylinder throw out bearing
transmission input shaft

If I had to guess for the grand prize, I'd go with throw out bearing.

I always hear whine when the engine whines down. Always have. Doesn't sound too loud or out of place - at least in my case.

My guess would be the timing chains whining on the gears, my whines too, I think it sounds kinda cool

So nothing really to worry about then?

I would have to go out on a limb here and
suspect the serpentine belt tensioner as
the noise maker. Do a noise check on it.
They seem to be going south at an alarming rate.

Sure that the wife wasn't in the passenger seat? That could make some whining sounds!

Power steering pump?
Low on fluid?
