The NBP CL-S my borther and I picked up came with some AEM lightweight pulleys. The only thing is though that the bigger of the 2 (is that the power steering pulley?) was installed and the smaller one was inside the box.

Can this mess up the car somehow or is it cool to run the bigger pulley without the smaller pulley as well?

 

I thought those aem pulleys were just for looks.What you got is a ps pulley and a alt pulley.No crank pulley.The crank pulley is where the performance is.either its from taking weight from the crank or underdiving accesories,or both for the most gain.I think its 2hp for every 1lbs off the crank.I bought these for a 2nd gen crx I built before but quickly realized they were for looks only.you can run the one with no problem

 

I didnt even realize AEM made pullies for the CL. I asked because on the highway I was on cruise control at 70mph. Then the rpms dipped a little and it slowed but then went back to the 2k rpm it was at on 70. That happened for like 5 sec then it went up to 2.5k rpm and then sped up still on cruise.

 

AEM does make 2 pulleys power steering and alternator...they r only for looks and weight reduction...useless..there is no crank pulley by AEM ..

 

They sure are purdy though...

 

Yes the bigger one is the P.S. pulley, but im still a little confused as what pulley was installed where......

 

the smaller pulley is the alternator pulley. Was that not installed?
