I want some underdrive pullleys. My question is which ones do I get? The three piece set or the two piece set, or the power (voltage) saver set?

 

First off everyone on here is going to tell you not to get them.

I personally like mine, the two piece set will give you more underdrive than the three piece set, thats the one i would suggest.

I had charging problems with the 3-piece set so I removed the March alternator pulley and put the stock one back on.

 

I say go for them. Two peice set though. I also had to remove my altenator pulley after going through quite a few altenators. I also have a decent stereo so that attributed to that fact. I definatly think they are worth it.

 

why would anyone tell him not to get them?

 

I run the 3 part set no problems here. One thing I dont like it the way i cant put the nut on all the way on my alternator. Anyone else have this problem?

 

The question you have to ask yourself is: Is 0.1 to 0.15 max gain worth potentially killing batteries and alternators on a regular basis from the lack of charging. Don't forget you could potentially get stranded if you do any real traveling because of this. If you do a lot of idling and low RPM driving especially things could get ugly.

 

Good point Ed. If you do around town cruising you will probably have trouble. If it's used more for highway/racing then you'll have no trouble.
