This was on a VW Beetle IIRC, not a Miata. :)

Re: [OTM] Sound of turbo
dieing? SOLVED
I could be off here... but I don't remember ANY vacuum pumps on the miata
setup, vacuum is sourced from the manifold without any pumps used. Its
then used by the FPR, a few other small usages and the Brake booster. Get
a better description of the issue, something is being lost in translation
or you guys got hosed.

Thanks for all the great suggestions. Mom took the car in for a timing
belt change this morning (didn't know she was bring it in so soon) and
they found the problem. Apparently there are two vacuum pumps on the car
and one of them was leaking while charging up the system (or something
like that). Getting that replaced was about $800 since it's nowhere near
the timing belt, it's somewhere on the back of the engine. The car is
whine free now (and I bet her brakes work better too).
Cheers,
Mark

the whining sound could be the alternator bearing on the pulley, or the
differential. My guess is that something is too tight or dry when cold,
then gets lubed or expands in the heat, quieting the noise. New belts
are sometimes overtightened when put on the alternator and drive
pulleys, and this puts pressure on the pulley bearings and may actually
cause them to wear prematurely. Proper alignment is necessary between
alternator pulley (or other items using pulleys) and the drive pulley.
