This my first post so if I pull up a old topic forgive my ***.I have a cooper s with the john cooper works kit and i want to put on the factory pulley they have, is thier anyone who has done this that can give any info on this set up.price/power increase/will it last

 

if you have the JCW kit on already you have the pully.

 

First off welcome to NAM. Now, the JCX kit comes with s supercharger that already has a reduction pulley on it. It is equal to the 15% reduction pulley that everyone is talking about. If you go to a factory pulley you are going backward to about what a stock MCS would have.

Cheers,

JD

Almost. I think it's about 13.8%.

 

Actually, I think it's more like 14.2% or so.

 

Hey guys thanks for the info.When I picked up my cooper s from the dealer he said that they sold a pulley for it and I thought it came with the pulley.I just didn't understand him. So know what else can I do to cooper s?Ralley lights?
