The newer HR/VHR internals are significantly stronger than the previous DE internals. In addtition, the torque curves are also significantly different between the two ... less torque out of the HR/VHR also helps engine/drivetrain life.
Even though the VHR was tuned to over 600+ WHp, it will still be recommended to keep the boost down for increased reliability.
Keep in mind the biggest factor in engine life is HOW the car is driven. A motor can be tuned to 1000 WHp and last quite a long time if the driver is not boosting from light to light.
