Get the smallest one you can find! Make that baby force that air in there! Wind it up till you see bits of pistons coming thru the bonnet!

I've seen 15% 16%, 17% and even 19% pulleys out there.
Factory pulley should be 65.5mm so, you can measure the one you have to determine how much smaller it is (example: 15% reduction would be ~55.675mm)

The po put a smaller pulley on my new to me 2006 Cooper S- are there various size smaller pulleys out there or is there just one size?
He has no information for me although the other mods to the car are high end.
Thanks
