Pulley's again

Hi All

So i have been doing all the necessary research and want to do the Sc pulley and ready to get cracking, but im not sure which size is currently on the car, its an R53 with the JCW kit added after, 190 bhp - what size pulley will the SC have

cheers all

The supercharger pulley in the JCW Kit is about a 11% reduction.

Thanks caveman ill go with the 15% then wish me luck i hear they can be a bit of a bug** to fit and remove but will be going to my mates garage to do it with all the right tools etc so hopefully i wont goose it up.

Ok problem now, the cooper has no ac andim going with a 15% pulley but for life of me can't find the right belt size anywhere literally looked on every site. Any ideas ? Cheers
