I am looking into buying the Unorthadox Pulleys for the S2K and i just wanted to see if anyone has these and if so have they had any problems after adding them. I really just want to make sure it dosent mess uo the harmonic balance of the engine which people have told me about.

 

The general concensus is to avoid changing the crank pulley. Since the power steering is electric there is no power steering pulley robbing power. There is no need for a larger pulley to slow alternator. They look nice and will allow the engine to rev a little quicker but you will not be able to detect the difference.

 

I've got probably 10k miles on a set of lightened pulleys and no problems with them so far. To be honest I did not notice much of a difference one way or the other though. A friend of mine had the pulleys and he had problems with the bearings at one point (they started making an awful noise under the hood) but he either replaced them or repacked them with grease, cant remember which, and his were fine after that.
