which UO racing pulleys are best for a 98 lude that will pass smog but not mess up the engine in the long run.......

 

I've been wanting to know some things about these pulleys too. UO is supposed to be the best, I hear. Has anyone ever experienced their alternator not charging as well with new pulleys or their power steering not working as well? It may be better after the upgrade... Just wondering because I only want the extra power as long as everything will remain efficient.
Don't mean to hijack but its a free bump!

 

spun bearings..

 

explain that.

 

I've got an UO crank pulley on my 4th gen. I tested the alternator at 13.6 volts at a warmed up idle. No problems.

As for spun bearings.... not yet.
