Thats exactly where I used to hear it also. I could put my ear on the chamber of my GT-40 intake and hear it wistle so thats why I initially thought it was an intake problem.

I mean you can hear it like 10 feet away but it sounds the loudest (if your in front of car the right side on upper intake manifold in the middle.)

Ok, i need help so bad i managed to get a decent video of the noise in here.

Don't pay attention to the booooommm noise its from the crappy camera but near the end u can hear the whistling/beeping noise the best.

Thats what I had only mine was alot louder to the point that people that didnt know any better thought that it was the sound of a turbo. The sound went away once the throttle opened up. Mine only made this sound at idle.
