I'm looking into buying a lightend crank pulley (for my GSR) maybe Unorthodox or something, just want to know some pros and cons about this mod I've heard both good and bad things, I recently installed AEM underdrive pulleys and I can tell a difference in them hope I get the same thing out of a crank pulley

 

I've read in other topics some say to get a CTR crank pulley or this "Fluidmapr" thing what's that

Also after installing an aftermarket crank pulley would I need to get my rotating assembly balanced

Do a search, there are a couple good threads on the CTR pulley. I love my CTR pulley

 

Did you have to do any balancing after installing the pulley?
