Hi guys,

Can anyone see any problems with fitting both the 17% Supercharger pulley and the 2% enlarged and lightened crank pulley - this would make around a 19% reduction but with less belt slip than a 19% S/C pulley.

Would it be more advisable to go with the 1% Crank?

Also, would I notice any significant power gains from fitting the Crank Pulley?? I already have the 17% S/C pulley and that has made a huge difference, so would the 2% crank pulley really make that much difference?

Thanks for any help!

how do guys,

having just bought a milltek, and with the ole birthday just round the corner I'll be ordering my GTT pulley etc shortly, but do a search on crank pulleys, I've been looking into it and theres some good threads on the topic.......

Hi Guys, the GTT +1% crank pulley is the one to use with our 17% SC pulley. The difference in performance is subjectivly 'more than an extra -1% on a SC pulley'. The light weight of it just brings the car to life more.

Roland,

Thanks for the reply, any idea of expected BHP gain from fitting the 1%?

Is the difference noticeable?

Cheers

I have the GTT 3% on my JCW and the difference is amazing. Winds up soooo much quicker.
