Honestly its somewhat difficult to hear while im driving. But from what I can hear yes it speeds up with revs. I know it only really happens once the car warms up. We had tightened the belt at one point and it definitely got louder. Once we loosened the belt up it went away for a bit and is now back but not as loud. I also sprayed a little belt spray on the cogged supercharger belt and the noise got quite a bit louder. At this point im hoping that means its not the blower its self and rather a bearing.
