pulleys: heat and charging
 

I have a stock cooling setup and a 130 amp alternator; I don't have any problems with either system (130 amp alt is GREAT!), but when i put on pulleys, how much will it change things? I recall most people saying that if you have a 130 amp underdrives are ok, but has anyone noticed a heat change? If so, should I get a better water pump and/or radiator?

Im running power pulleys no heating problem
but notice drop in voltage with lights on or any acc.

I put on the March Aluminum U/D pulleys (all 3) and I noticed a big drop in charging, and had a dead battery within months. Then, I upgraded to the 130A alt, and have had no problems for over 3 years. I noticed no change in cooling after installing the pulleys - I have a fairly big stereo, but do not run my A/C at all.
