Identifying aftermarket pulleys
I just bought a 2010 370Z from a dealership which has some work done; full FI exhaust, LED's, and some other aftermarket products. I'm trying to figure out if the previous owner bought UpRev and/or replaced the stock pulley with either a lightweight or an underdrive. Is there anyway I can tell if I have UpRev or pulleys just from looking? My voltage meter is always right at 14 or a little above... I know this isn't much help.
All of the pulleys look to be black EXCEPT for the crank pulley which looks to be polished or aluminum of some sort. Here are the best pic's I could get....
Thanks!
