    Supercharger/ Lid Tq Specs

    I did a quick search on here and didn't come up with anything. Does anyone have the tq specs for the blower and lid bolts?

    Thanks

    since gm doesn't service the supercharger in this way, I'm going to say no one will know. you're going to have to take a guess, mine would be <22ft/lbs since it aluminum threads

    The lid doesn't come with the supercharger. So there should be torq specs for it.

    Doesn't Lingenfelter have a write up? I think its 22lbs not 100% sure though.

    didn't know that. I thought they didn't mess with the units at all..

    in that case, I'd use the 22ft/lbs rule. That's generally the max for aluminum threads as I said previously.

    22 foot pounds is pretty steep for a small bolt! Isn't that only about a 6MM or so?

    It is like 100 inch pounds. I have the manuals at home and I usually torque mine to 8 lbs. I will look it up when I get home.

    Neither did I until I saw a couple on ebay w/o the lid and the dealer re-used my lid. And this pic too. http://www.camaro5.com/forums/attach...0&d=1254086216 Also, the lid has the intercooler so they are probably trying to save money that way too.

    Re: Supercharger/ Lid Tq Specs

    From my 2010 GM Shop manual:

    (all listings have the prefix "Supercharger")

    Be sure to double check for "inches" vs "feet". (For clarity, the 37's and 18's are feet. The rest are inches.)

    Air Outlet Pressure Sensor Bolt = 89 lb in
    Barometric Pressure Sensor Bolt = 89 lb in
    Belt Idler Pulley Bolt = 37 lb ft
    Belt Idler Pulley Bracket Bolt = 37 lb ft
    Belt Tensioner Bolt = 37 lb ft
    Bypass Valve Actuator Bolts = 18 lb ft
    Charge Air Bypass Regulator Solenoid Bolt = 89 lb in
    Inlet Air Pressure Sensor Bolt = 89 lb in
    Charge Air Cooler-to-Cover bolts = 89 lb in
    Charge Air Cooler Outlet Pipe Bolts = 89 lb in
    Charge Air Cooler Isolator Bolts = 44 lb in
    Lower - Manifold-to-Cylinder Head Bolts - First Pass in Sequence = 44 lb in
    Lower - Manifold-to-Cylinder Head Bolts - Final Pass in Sequence = 89 lb in
    Upper - Charge Air Cooler Cover Bolts - First Pass in Sequence = 44 lb in
    Upper - Charge Air Cooler Cover Bolts - Final Pass in Sequence = 89 lb in

    Thanks for posting. Will be changing out the SC this weekend for a ported one and was wondering the same thing.

    Also, it's a two step process... First pass is like 44, and the final is 89 and that is inch lbs, not ft lbs... You'll snap the bolt if you use the wrong measurement.
