Stock Axle Torque Strength Specs

Any know or have a link to the torque ratings and design specs of S197 axles?

Currious as to how much torque they are rated at or designed to handle per Ford design specs, especially in regards to very sticky tires at the track and how much the stock axles can handle before risking breakage.

And also using Moser's Torque Calculator at:

I don't think I've seen very many people have trouble with these axles yet

I think NHRA rules will force you to change them before they reach a breaking point.

Ok then, in those terms, what are the breaking points? How much instantaneous torque can be applied before they will break? What are the designed to handle?
