My info is not worth much as I do not race or drag but run it through the hills and have a bit of straight line fun with it. I would think if you are going hard all of the time and trying to go quicker , even with my 618AWHP and a lot of torque could cause some problems but as GTRNUR said, there are some real beasts running 800 to 1000HP
Mine is 461KW , 1000Nm around 4000rpm. Getrag 6, twin coppermix C spec, quaif front diff, trannie has a few more plates, a Nismo2-way lsd and 265x35 AD08Rs. So it spreads the load to all wheels and puts a lot of twist on the box, only spins wheels a bit if it is a freezing morning. I stopped dropping the clutch but when I did I loaded it first.
Has handled it well, except I nearly fried the clutch being a DH the other day, but after the smoke drifted off, OK again, lol
