I have heard more testimonials on this board of the "it didn't hurt my engine" nature that or "it blew my motor" nature.
But no answer and proof.

Should I get one?
What is the difference between CTR N1 pulley and Unorthodox?

 

I have the UR race pulley on my engine for 10,000 miles so far and the car runs great! Don't get there clutch becase it squeaks. I persoanlly hate the mangement of Unorthodox racing becasue of there incompetence and lies to me.

 

UR pulley is only 12 oz. I would get the CTR pulley
