VAC motorsport underdrive pulleys

Anyone hear anything good or have any experience with VAC motorsport underdrive pulleys?

I'm wondering if I can just run the the p/s & waterpump pulleys and not the alternator with their kit?

Searched around in the forums and didn't get much help.

Thanks all,

The alt. pulley is useless anyways as the alternator is a generator so it only provides a certain amount of resistance (to charge the battery) no matter the size.

Hmm well I don't want to underdrive the alternator due to some concerns I've been reading on the forums - I'm just not sure if the length of the serpentine belt would be an issue with the alternator pulley left out.
