It could be a turbo on your 420a (after viewing my post I could see this comming off as an insult to 420a guys that do turbo theres. Its just a comment that his has one and he doesnt know). It could be a number of things pulleys,belts, the intake or exhuast. Where is the sound comming from? Maybe try and post a video.

i didn't mean it as an insult it was just a reference, it started after i replaced the PS/AC belt and the bearing in the tensioner pulley, but i don't know if it's the belt or the bearing, if it's just normal or not.
