Re: Code 3 pulley installed : Pulley rubs/not flat
Gen 1 and 2 were all steel. The last Gen was aluminum. There where some concerns that the cut grooves would eat through belts, but I think most issues were installer error. I do believe that is why he is going back to this. As I mentioned, I have one of the pulleys from the first batch made and have had ZERO issues. No belt slip, upwards of 19lbs of boost in the cold and have 10K miles on the pulley and the original stock belt.
