Default 996tt Clutch install

Hello, I bought a Dual Mass flywheel from Pelican Parts and I can't find the torque specs for a Turbo.
Bentley Manual on page 30-2 says tighten flywheel to 19 ft-lbs then tighten an additional 90 degrees (this for Carreras).
The book, "101 Projects for Your Porsche 911" on page 161 says tighten to the final torque value then crank the bolts another 120 degrees.
The 2000+ page PDF manual I bought lists all the torques except the flywheel torque specs.
Does anyone know the proper torque specs for the dual mass flywheel on a 2004 996 turbo?
Thanks,
Warren

It's on page 385 "Tightening torques for M 96/70 engine"

Flywheel on crankshaft : M10 : 85Nm (63 ft/lb)

No mention of a torque to yield so no "35 Nm + 1/4 turn" stuff.

Thank you for the help.
I do have that manual, I was not able to find it.
It is right there on page 385 like you said.
I'll head to the garage and torque them to 63 ft/lb.
Thank you,
Warren

You're welcome. That manual is not easy to search, that's for sure. Good luck with your project!
