Though a nitrous car can be set to mimick a turbo curve, as shown below. Really it is the low rpm torque that does the damage more often on stock blocks, not the HP. I finally busted a ringland on stockblock LS6 with 665rwtq @ about 3200rpm. So multi stage (my choice) or progressive can allow a higher overall HP by limiting the low rpm torque.
Here's my buddy's turbo set-up, check out how slow the tq comes on, and how late the torque peak comes, compared to some of us that have the mega tq spike down low. 
and here's the turbo/nitrous overlay showing n2o can be set-up like a turbo (these are small hits just for reference, but you get the idea). Mine was dual staged, while Joe's was not.

I can't see the images; however, if they are dyno graphs, keep in mind that they do NOT represent how the turbo car will act on the street... In 4thgear on a dynojet, if I keep my catback on, I can only make 10psi, and that is at the very end of the pull.... in 4th gear ON THE STREET, I can make 15-16psi by the mid 2K-rpms....
But not to detract, I totally agree that the nitrous torque spike is much more violent.
