It's not me, it's you.
I'm reaching out for a buddy of mine. He's working on a 2002 Mustang GT 4.6. He says they installed a Saleen Supercharger on it and they believe that they are missing a pulley/tensioner. I know the pictures suck, I've asked him to send me more. From what I can see it looks like there could be another pulley that goes on the left side of the left picture. If anyone knows the proper routing and a part number for the missing pulley, that would be appreciated. Thanks!
