Pully's Question

I think with underdrives you change the crank and waterpump, not the power steering pulley.

I have underdrive crank and waterpump pulleys, and the stock alt. pulley. At idle my car charges 14.6v. That is with no lights or accessories on.
 
I have the motorsport U/D pulleys on my car.. Had to take the alt pulley off cuz wasn't charging as well as i wanted it to at idle.. lights would get to dim specially with radio and heater on at the same time, not to mention all the gauges..
