I can just swear it is coming from the fenderwell where I put in the cold air intake, it also got a little louder after I put the intake in. So I'm stumped but it goes away after a minute or two so I guess it'* not too bad.
As expected, your car idled fine. Which is why I told you to start it with no SC belt.
If the noise only happens in the first few seconds of a cold start, I bet the noise is coming from air passing through the IAC passage as the idle settles in. If it got louder from the intake, and the noise isn't changed when the SC isn't spinning, this is normal noise at startup. Think of it as a modern choke.
