Maximum power that the DCT can handle

What is the max power that the DCT can handle? And what is the maximum power that the N54 can produce?

BMW Z4 35i  [0.00] will give you an idea what the DCT can handle.
The N54 can reach up to 550hp with mods like FMIC, DP's, race gas, meth kit, aftermarket exhaust and a remap.
The question is if the DCT can handle this? I'm not sure but it will cost you alot of money if something goes wrong.

With my setup i should be around 510 wheels Nm peak.
99% it's only a sensation... because theoretically I’m still far from the DCT torque limit...
…but when i floor @ mid-range in 6th or 7th gear on the highway it seems that the clutch slips a little, little bit.
Anyone else experimenting the same?

Design and materials have been trying to minimize clutch slippage for a long time. IF you play you're gonna pay. Every MT e89 will be replacing their clutches between 30k and 100k depending on the nut behind the wheel. Sport and Sport+ in DCT will shorten the life compared to Normal. Clutch preservation and DCT torque handlng limit are reasons why DSC OFF, long press, resets the shift speed program to slowest Normal mode. I only drive with DSC Off so when I make 400+ whp I'm not also banging the clutch in fast and super fast shift modes of Sport or Sport+. Most of us program boost in 1st and 2nd gear to 9psi and 12 psi respectively to save tires and then let 3rd and 4th target 17psi ...and those with meth do not flow at all in 6th and 7th gear to save 400+ wtq from trying to translate through the DCT at high rpms. My M3 clutch slips in my SMG but it has 104k miles. Be glad we don't have the $20K clutch replacements as the Carrera GT that only last 15-20k miles if driven correct.
