are underdrive pullys worth it

are underdrive pullys worth it, will they kill my battery cause it wont charge right, and how much of a gain will i see any info is great

They wont do anything to the battery, typical gains are seen around 11-15rwhp.
Only thing is dont run the A/C with these pullies at really high RPMs. Its ok for normal driving though. So, yes they are worth it!

They are worth it--just make sure to get the crank and alternator pulley as a set.

hey hillbilly...what part of ri are ya from? i grew up in providence...

ive been looking around but i cant seem to find any kits that say crank and alternator...where did you get yours?

Hitman X on this site sells them for I believe 225$ Shipped which is a good price in the for sale section. Search the forum for ASP Underdrive Pulleys and PM Hitman X for more info. Thats who I got mine from.

foster we were the kids who always had no school when it snowed

yeah i remember waking up early before school started to watch the news for closings...i was always disappointed though

thanks man i appreciate the info...i might have to decide between headers and a pulley though...ima go with headers if i cant get both
