My car has like a whistle sound to it at all speeds.Gets higher in pitch at greater rpms.Thought it was a tensioner pulley, reaplced them both. A friend says it may be the brushes in the alternator? Does this sound right? Car runs great, no difference in performance.

x2. Sounds like Vacuum leak. Check all of the lines of your vacuum cluster.

A new TB or plenum can do that. My brother's car did it as the idler pulley was going out also.

+1 My TB does this. It's just the nature of the beast. I think it sounds cool, so it does not bother me. If I were you. I'd start by checking the air intake system for any loose fittings/connections. If you can't find it there, then start looking at all the vac. lines in the engine bay.

keep us posted.

My C@L Tru-Flo Intake gives off a whistling sound. I think it sounds cool. A cheap alternative to a supercharger whistle.

My 70mm Throttle Body whistles different tones at various throttle positions... Not KB cool, but doesn't sound bad.
