Underdrive pullies ok with S/C?

I have a 330ci friend that has the Rogue underdrive pullies on his waterpump and powersteering but not the alternator. He wanted to know if he has to put the stock pullies on when doing his Supercharger. He thinks it would counteract the pully size of his ASA S/C. I'm thinking it would not change it just like it doesn't change how his alternator is spinning. Since the belt is self adjusting and only touching a small side of the pully and not the whole diameter is should be ok. What is correct?

stock pulleys, the difference in the belt can change at higher rpm and slip.

I asked the same question to the makers of the kit and thats the answer. stock pulleys

the SC will make you forget you evAr had pulleys.

i had to give up my old RE set away with the belt for free
