11 psi from a centrifugal supercharger that makes 11 psi only at redline and makes only about 3 psi at 4150 rpm cannot be compared to a twin turbo car running 11 psi that makes 11 psi at 4150 rpm in terms of stress on the motor, although to fully analyze we would need to know that the turbos and their total cfm is at least comparable. In general, centrifugal is much less stressful than turbo due to the boost curve. With good wastegating and electronic boost control, turbo boost can be brought in more gradually to preserve a motor.
