TSE BBK Bracket Torque
TSE says factory spec on these brackets(36-51 ft/lb), they are using std 3/8 hardware and the bracket doesn't have a steel insert.
Assuming they are 6061-T6 I am finding the suggested torque with .500" of thread engagement to be 24 ft/lb with a max torque of 32ft/lb. What are you guys torquing your bracket bolts to? You guys using loctite on the bolts? Calculator is here:FUTEK Bolt Torque Calculator | Bolt Torque Calculators |
My 11.75" brackets have steel inserts....

I've never stripped one of the threaded holes in our brackets, nor have I ever heard of anyone else stripping the threads out. I would stick with the factory torque spec. |

News to me - our brackets don't.

I see your machine shop experience and raise you my own. Where we did no such thing.
If the threads might fail, the insert might fail. Might as well make the whole thing steel! /dumb |

I was hoping to get some, "I run 275 hoosiers and XP20's, torque to 50ft lb, car weighs 2500, had my BBK for 2 yrs, had the brackets off 8 times, and no issues" type responses. |
Threaded insert is no panacea. I've stripped the insert out of one of my Goodwin Racing brackets just torquing it to 40 ft-lbs.

You realize an insert would increase the thread torque rating right(larger ID on the alum would increase the surface area)?
