you are right..it is from the air trap between the belt and pulley;
That is where the whine sound comes from. Most of the street cars with a blower, have a 1/2 pitch belt. The teeth on the belt are flat. When the teeth mesh with the pulley, the air is smashed and there is your whine.
An 8mm pulley and belt are of a rounded shape, and are not nearly as loud.
