Fellas, the supercharger tensioner in my m113k needs to be replaced. It barely holds the SC belt tight and the whole thing squeaks like an old Alvin and the chipmunks record. Ive searched this forum for a diy thread but can't find one. Was going to buy Shardul's pulley set, but i'm needing to replace the tensioner first. Looks fairly straight forward but I don't know about torque specs, etc. Any help here would be awesome. I'd like to take pictures as I go and make a diy for this forum, but i think I need other members help.

the torque spec for the tensioner is 18 ft-lb (25 nm)
the torque spec for the idler pulley is 14 ft-lb (20 nm).
