"Real" load is measured in peak cylinder pressure and brake mean effective pressure. Since lab-grade combustion analysis equipment costs as much as most people's cars, we're left quibbling over this stuff.

It's basically flat from 3500-5250, and I bet if you looked at the engine map there is a constant load between those two points.
Most new turbo engines have flat torque curves from about 1800-5500rpm. Have you looked at the dyno curves on new BMW (M5) and Audi (S8) twin turbo V8's?
