Hey, has anyone install a underdrive pulley on their car with a high current system
I understand the pulley will slow down your accessories, will I have any problems charging the battery and running the system and will my lights blink
I current have a jvc radio, indash screen, ps2, 4 channel amp on the highs, 1400 watt amp on 2 punch 12's and a 1f lighting cap

 

Is it just a lightened pulley or smaller?

Also which amps?

 

the voltage drop was on the ugly side. it was on motorvate.ca i believe you would get your info
Here

 

the pulley is smaller

 

Thanks for the link never heard of it before
