I've seen 275lbft dyno on a new LuK without problems. And that is a decent dyno dynamics set up that is ramping up slowly.
The big issue for the clutch is as much how fast you apply high torque loads. Once you get a bit of slip it'll slip away faster and faster. So a gentle torque curve shape can still be large.
However many people like the 'kick' too, which doesn't treat clutches as nicely.
In the end you'll easily be able to run 150bhp/240lbft with a new LuK clutch without any problems at all. Just don't abuse it and it'll last for years.
I have one customer who ran 275lbft on his new LuK and apart from a few rare occasions where it slipped a tiny bit in 5th up hill at 2500rpm, it was fine 3 years later!
In the end I think the stage 2's drive just as well and perform just as nicely with a lowered torque peak vs those with fancy clutches.
I'd rather spend my money saved not buying a fancy clutch on a hybrid turbo to add power up top
