it says it all... is it possible?

 

Yah...why not. Just blows the JCW warranty out of the water should you have a problem.

 

well, the real thing is how do I remove the JCW pulley from the SC?

 

Go for it. What could go wrong?

 

Just like every other pulley upgrade. Your sig shows that you have a 15% pulley? Maybe the person who installed it can help/do that one.

 

Last words Capt. HMS Titanic.......

 

I have an 06 MCS with the JCW package. I have the 19% pulley installed with the GIAC upgrade. I am hitting approximately 17 lbs of boost and has made a big difference in performance. All around driveability has improved also. It was done by Eric at Helix.

Doesn't make sense to spend all that money on the Works Kit and then change out the pulley.

Leave the Kit asis and install an oversize crank pulley if you want more power.

 

X 2 !

I think MINIAC is right. You have a 14.xx% reduction pulley and should keep the JCW package as it is. Go for a crank pulley instead.

Also, you might want to get a better ECU software. It's a great think and makes a Cooper S much better... MTH Tuner or Giac are great.

 

Well, it is actually for my friends car, he has a Factory tuned 06 JCW MCS and he said that he wants more power now even if he voids his JCW waranty He got an ALTA 19% pulley from ebay and now the question is how can I remove the JCW pulley from the SC as my puller is for stock pulley... gas ax?
