>>I have a '91 Special Edition Miata with about 28k miles.  I have been
hearing a high pitched hissing at about 4000 rpm's (any gear) and higher.
Does anyone
know what this is (maybe the belts)?  BTW, I am not loosing any power when
hearing this noise and happens with the ac on and off.

Thanks in advance.

This may or may not be related, I also have a 91 BRG but with only 30K miles.
I have recently noticed a high pitched whine or hiss from under the middle to
middle/front of the car.  Especially when in a fast food line where the sound
bounces back up.  I have noticed that when I very lightly rest my foot on the
clutch, the sound goes away leading me to believe it may be the throw-out
bearing.  Any comments/suggestions before I have what had better be warranty
work done?
