Hey Guy`s, I have my PC installed and am now tuning with Tom, My question is the idle noise the super charger makes. I have listened to all the videos I could find. Most make a kind of rattling noise. Very metalicky? I took it back off to double check it. No up or down movement on the impeller bearing. But there is back and forth movement,maybe a 1000th of an inch. I can dublicate the noise with the engine off, by just tapping the serpentine belt. I installed a new key way in the pulley side. Is this sound normal? runs great other than this noise. Thanks for the input.
