what is the difference between the renntech and evo sport pulleys ? how are they made ? and what is the price difference ? and where can i get an air filter ? thanks for the help.

I will have some pictures and more info by this Friday. Please stay tuned - ODPS kit is just about ready.

i think the major difference is that renntech has a harmonic dampener on their pulley and the evosport is a solid one w/o it. search thru the archives and search for harmonic. big discussion on it.

Here is a photo of what comes in the Renntech kit.

anything new regarding this? friday came and went.
