JCW question

The JCW site on MINIUSA.com only says:

Quote:

At the heart of the MINI Cooper S tuning kit is the supercharger. Incorporating a new pulley design, this unit spins at a higher rpm, generating even better engine performance.

I assume this means it has a reduced pulley. Does anyone know by what % it is from the stock S pulley?

I believe it is just under 15%. The exact reduction is around here if you search hard enough, but most people simply equate it with the aftermarket 15% pulleys.

But the alloy used in the JCW pulley has a much higher crap content than any other aftermarket unit.

Thanks for the replies. I searched earlier and couldn't find the answers I was hoping to find via this thread. Chalk it up to poor searching. Now that I had some more time on my hands I've found everything I wanted with better search criteria.

I was thinking 13.7% off the top of my head, not positive though.
