well. i guess its better to hear about this now and not after i installed it! (nailbyt) let us know brach.Everyone with the Protege Crank pulley, do not install it yet. I have had 1 person have the screws on the backing plate back out. The screws are lock tighted in and should not back out. So I need to get to the bottom of it and make sure this is a fluck thing. If you feel you need to install it, put some sealant/RTV over the screws, however, I would rather you wait until I try some tests. So please be patient 1-2 days while I try out a few things.
Underdrive pulleys are smaller in diameter and lighweight..where as brachs is all lightweight and no underdrive. With Brachs crank pulley you can reuse your stock belts if they are in good condition, which you can't do with the unorthodox. Underdriven pulleys are hypothetically supposed to give a little more of a gain, but that is slim to none..because all the gains are found in the lighter weight of the pulley compared to stock.Excuse the n00b question here, but I never really researched pulleys that much, but can someone tell me if underdrive and crank pulleys are the same thing? And does your crank pulley come with the belts?
Ebay has OBX underdrive pulley that sells in the $80 range, and Unorthodox pulley's selling for $180ish (Why the big difference in price?). Then you got your crank pulley, SLS crank pulley going for the $160 range.
I hope someone can tell me the differences between them all thanks.
