Does anyone know the torque specs for the supercharger outlet air "horn" bolts. These are the 4 bolts that screw the outlet horn to the supercharger. I've browsed the net for hours and can't seem to find the spec.

Btw, anyone looking for the supercharger bolt torque specs.

According to the Bentley manual: The bolts to the engine
M8 bolts = 18 ft-lb; M10 bolts = 33 ft-lb.
(Thanks Searocko)

Inlet Air bullhorn to intake manifold
12 ft-lbs (from TIS)

Plastic inlet hose thingy from throttle body to supercharger
6.5 ft-lbs (9nm) (from TIS)

If you attempt to rebuild the supercharger snout, I believe the bolts are torqued at 18 ft-lbs (from my rebuild kit).

 

18 ft-lbs for those M8 bolts. If you're re-using them put some blue loctite on them.
