2ZZ Squealing Sound Throttle Body ??? - Toyota Nation Forum : Toyota Car and Truck Forums

Hello all, I have a 06 lotus exige with a BWR supercharger on it. I developed a loud annoying squeal at all RPMs. I have taken off the serpentine belt and it still squeals. Has anyone with this engine experienced a sound like this or have any recommendations as to what it could be? It sounds and feels like its coming from the throttle body (not sure if its the same, it is a toyota part so I'm guessing it is)

here is a video with the sound: http://www.youtube.com/watch?v=pkUMq2_xCAQ

what type of S/C is it? i've seen some superchargers (mostly centrifugals) that make that kind of sound. but im sure you could ask this question on a lotus forum to get an answer
