Supercharger make pulsing noise

I have had OTTP stage 1 for a long time now and just the other day I was doing a second gear 40 pull and with the window up you cant really hear it but with the window down the supercharger make a "pulsing" whine sound. (wha wha wha wha wha) (not just a long even whine. Any ideas? It still seems to run GREAT, but the sound is different.

Anyone? this is weird as heck...

Was the car jerking?
if so sounds like your missing or not getting fuel.

Car wasnt jerking at all...

The pulses are superfast 5 persecond at 3k rpm and by 7 k rpm they are so close together you cant tell anymore... power is awesome and everything.
i'm confused
