I dont think you will find alot of cars out there exceeding 550/570nm. Most (stage2) tunes for our car wont give you more than 530 to 550nm (on stock turbos that is). So talking about 600nm would be talking about upgraded turbos and pushing close to 19/20psi (thats the max PSI you can go, limited by the fueling system of the N54). Getrac has rated the transmission to 600nm max always being conservative for everyday applications just like all OEM manufacturers, tuners have stated that this transmission is good for about of 700nm of Torque. Now if you're talking about Nitrous then its a different topic but we ARE talking about the JB4 and average dyno numbers on 15.5 with that specific tune, with 92 Octane fuel Full bolt on's and meth give around 430nm of Torque which is more than safe and thats directly quoted by a dynograph from Burger Motorsports JB4 equipped N54 car
