That means its fairly safe for huge amount of torque. 335i ZF are rated much less than that and people put 450-500 TQ on theirs without any issues! Look at 335i MRC, they have almost 550 TQ at theirs and its no diesel!
I believe our tranny can support up to 650 TQ
This guy doesn't want to be the person to find the "limit" . . .
ZF tells me the 'limit' is 700Nm. I know that there is 'overhead' but I'm not going there. 12 sec 1/4 mi times are awesome but not for me if the engine mods push over 510 lb•ft. You do what you like to yours, I intend to keep mine for a while and a blown trans isn't worth 12 sec 1/4 miles.
