Rotational chirp, not belt related??
 
So, I'm hoping this is a known issue with Boxsters. I bought mine with a chirping sound that I swore would have been the throw out bearing. I changed it, along with the clutch, pilot bearing, and the IMS as long as I was there. The IMS with 100K was still perfect... Anyway, I ruled out belt / pulley noises by disconnecting the belt and running the engine, the noise is still there. The car is quiet on a cold start up, the noise will start coming on after about 5-10 minutes running. The noise will also go away at around 1500-1800RPM. It is primarily there at idle. Does anyone have any thoughts as to which direction to go to figure this out?

Loose spark plug? It's a fairly common problem that often gets overlooked. Also possibly a worn timing chain guide can cause a chirp.

Thanks for the tips. I'm back at it tonight with a stethoscope to see if I can at least locate the area the sound is coming from.....

I'd second the spark plugs. If they haven't been changed in a while might be good to do them. Not a bad job with the proper tools.
