Under drive pulleys

[CrystalWhiteChristine]

hows it going every one, so I want to get some UDP i can get a set of fms for like $120 at the local performance parts shop, my question is I noticed the warning on the pulleys that it will slow w/p speed and alternator charge, Just wondering how big of a difference it will make and if its worth puting all the pulleys or just the crank shaft. thanks guys

I don't think it is worth it.

They burnt up the alternator on my old mustang.

IMO save your money for something else.

I don't run them. Not worth the sacrifice for a few hp IMO.
