size of JCW pulley in MM?

hey guys,

have any of you ever measured the JCW pulley? what did it measure in milimeters?

I know what the reduction is supposed to be, but i would like a figure from those who have put a mic on the JCW pulley

yes i know...

but i have a client/friend of mine who is swearing he just went out to his gp and his pulley measured 65mm!

he is a very competent person too!!!!

He had the car dynoed for good measure and it put down about 175whp with 50 miles on the odo... but he is swearing it is 65mm!

I know the works kit is the same on the gp except for the intercooler and the rev limiter.

I was just trying to get a feel if anyone has actually measured there pulley... more importantly on a GP.

It will be two weeks before i can get over and measure it personally...
