i am planning on getting performance underdrive pulleys, i heard that i would need to upgrade my altinator. in this case what kind of pulleys are best and what amp altinator would i need.

pulleys are pulleys to my understanding.

the only differences are the materials they are made of but this doesnt affect performance, only weight.

and if you go to the junkyard you can rob an alternator of a 94 or newer mustang, or a lincoln markVII

these are stronger alternators and cheaper alternative than buying a new one.

Remember to cut the wiring out of that scrap yard altenator and take it with you!

I was gonna get a set but to be honest u dont get any real performance gain just more astetics..

if u are gonna do it just buy the cheepest set u can get in the color/design u like. make sure to get ready to resize your belt, and I really dont think u will need a bigger alternator

not really from rolling movements then to flooring it u feel the differenece. I reccomend that and the smog delete and the a/c delete. you will see a difference.

If you go with a pully set, you will want to upgrade to a 130amp alternator and I used the same belt. They say they give you 5 to 10 horse add that with a smog delete, you will notice a difference.

you may not gain that much hp but you will have much better throtle response.

you guys do know that the pulley kit comes with a smaller alt pulley that then speeds up your alt to normal speed so you don't need to buy a better alt?

i know that. But the smaller pulley usually burns up the alternator.
