e.g if you had a pully which was 100mm and you went for a 15% reduction you would be getting a pully that is 85mm.

21.
Standard Cooper S has a larger pulley than say the JCW which is 11% smaller than the standard Cooper S pulley
So on a JCW you would really only want a 4% smaller pulley which I don't think even exists.

Yes.
Gives me a better idea of how much smaller a 15% pulley is.

think about it like gears on a bike, smaller the pulley, the faster your legs would turn to gain one revoloution
now if the crank is driving the supercharger via a pulley, the smaller pulley will alloy for more revolutions dispite the same rpm
