TR6060 Max Torque

I was going through the wiki on this site, and I saw that the TR6060 was rated for a maximum of 430 ft.lbs (gearbox) of torque. More research on the TR6060 states that it is rated for a maximum of 600 ft.lbs of torque.
Is there a problem with the wiki, is the clutch rating acting as a limiter, or are there some weaker components in the 2010 Camaro version?

Obviously, this is a cause for concern, because you should avoid out-torquing your transmission/clutch, and the way the wiki is written, that doesn't leave a lot of room for improvement.

The 430 number seems very low. For the 6L80 the gearbox torque number is a lot higher than the max engine torque. But, like you said, perhaps the OEM clutch is a limiter. There's a formula I believe for the 6L80's that calculates gearbox torque from max engine torque. I think gearbox is 1.5 times max engine torque. I could be wrong. I'm not sure if there is a similar formula for the M6.

It seems that once M6 owners buy the new 1000 rwhp twin disc clutches, their cars can handle 500-650 rwhp no problem.

As an A6 owner, I'm obviously jealous.

The torque rating for the TR6060 is NOT the maximum torque that the transmission can take before something breaks. It just means that it has been rated at 430 ft-lbs. to live for the life of the vehicle with durability testing run at 430 ft-lbs. A good rule of thumb in automotive design is that a safety factor of 3 is usually what most components are designed to in automotive applications.
