i know this have been asked and talked about a million times, but ive been reading alot of em, but im still confused lol,
im looking at gettin underdrive pullys for my rig, and im unsure what im looking for, is it the smaller alt. pully and larger crank pully? and changing the the alt pully to a smaller will that change the output, will it ruin the alt??? any helpful link or supplier link? thanks

 

I've read where very few people who have done this would actually suggest it to someone else. Not worth it seems to be the general review.

 

They're just not practical for a street vehicle. You most likely will encounter problems running accessories due to low voltage.

 

ok thanks for the relays, ive researched and read a few articals on it and i dont think ill bother with it for work involed and the possabile promblems and what you gets out of it for a street, everyday vehicle not worth it.
