Default Re: Supercharger snout bolt torque?

Thank you Dave. After not seeing it in the SC / CAC remove & replace section, the first thing I thought of was to ask the pros here. I didn't realize that we have a torque spec. chart in the introduction portion 8. All you have to learn is how to read it. After a little study I see that the snout bolt is an 8mm dia. flange bolt, 1.25 pitch, and stamped with NF/8.8.(I believe means Class 8.8?) Our chart shows Class 8 or Class 9, so either 24 ft.lbs. for class 8, or 27 ft.lbs. for class 9. Since I'm using blue threadlock, and 24 ft.lbs. seems like plenty; that's what I'm looking at. Does all that sound right to you Dave? NF means; National Fine (thread).
