RogerS Posted July 28, 2008 Report Share Posted July 28, 2008 Another pending project completed. Solved the clearance issues. A significant upgrade from the factory aux. pulleys. Not that difficult to complete. And they are rebuildable. You will notice also that I did install the tensioner support brace to prevent the tensioner from "walking" during high boost runs. During the process I did identify another potential weak link in the system. The lower pulley is made of plastic! But a 91 SVT Cobra has the same pulley in steel. Time to go to the Ford parts department. Anyone running boost should really consider this upgrade. After inspecting the inside bearings of the factory pulleys I could see it was not going to be long before they would give. There were cracks already forming in the bearing insulation. Now to clean up the crank damper! YUCK!!!!! The before: The after: Link to comment Share on other sites More sharing options...
