Intake chirp and rev whine - please help diagnose these sound clips

[Alan Mackew]

My 2003 2.7 tip has whined ever since I bought it 3 years ago, it is particularly loud when cold, I have always assumed they all do that having read a road test where the tester remarked that the Boxster makes similar noises to the old air-cooled cars,
Perhaps I should be worrying my service guy has never mentioned it,

Cheers

Cool, thanks. Does it sound similar to mine in the second video below? It seems more noticeable and whiny in the second half of the clip.

I would take the belt off to see if both or either of the noises go away. It could be a bad belt or one of the pulleys. The chirping noise could also be caused by a loose spark plug. Both of these suggestions are free and pretty easy to do.

Thank you! I'll replace the serpentine belt today and see what happens. I assume it's safe to run the engine without the belt for a moment to see if the whine is gone? If it is, and therefore it points to one of the pulleys, what is my next course of action?
