#38510, "Poll question: Turbo Guys - How high did you torque down ARP head studs?"
ive been seeing a lot of different numbers for the arp head studs. The main site says 71 ft-lbs, ive read 75ft-lbs elesewhere, ive also read to go to 80ft-lbs if you plan on making some decent power, and had a great chat last night with Armond and he mentioned he torques his down to 95ft-lbs.
I would say screw it, and go real tight, but ive also read that going to tight will crush the mls gasket
opinions, thoughts?
-- ive done a search and thats part of how i ended up with different numbers

For an average turbo setup, 71-80 is fine. I torqued mine to 80 because that's my torque wrench limit. Seriously boosted applications (25+ psi) should have them torqued to 91-95 ft lbs.

Mine are at 90ft/lbs.
it's a five layer steel gasket. It won't crush much anyway.

Wow, 95 ft-lbs huh... I torqued mine down to 76 ft-lbs this past weekend and I would imagine that would be plenty for some high boost. It better be anyway, because if I wind up having to take this stupid engine apart again soon, im gonna be maaaaad lol.

I torque mine to ARP standards. I have never had to up the torque on it for whatever reason and although i dont push 20lbs of boost, i doubt you want to torque it beyond the arp spec as you may go beyond what the vendor designed that stud for.
