Hi guys,

I have separate clips of two different, but annoying and maybe concerning noises that I'm clueless on.

The first is a chirp upon an initial blip of the throttle seemingly coming from the air intake. I am de-snorkeled.

The second is a whine that corresponds with the engine's revs. It's the same whether in gear or in neutral, clutch in or out. I installed a 997 shifter today and don't recall hearing the sound previously, but I could be wrong. I recently had my water pump replaced. Could it be the serpentine belt? It's not the transmission right, since it's the same whether in or out of gear?

Sorry for the crappy videos, but I didn't know how else to record the sound. Thanks in advance for any help you can offer!
