What is recommended best practice for the firewall on a rotary, will 0.16 inch thick 301 stainless with fiberfrax be ok.
Is this combination good enough to buy time in case of accidental exhaust fracture or something along those lines

You must mean .16 mm Alex. .16 inch would buy infinity :)
It would also weigh about 30 pounds.

.016 or .020 inch SS is mostly used.

Check out the bottom of the RENL web site front page. Some of the parts are
coming in for the motor mount.
