As a more historical example of this, a lot of WWII fighters had a max power setting on the throttle that had a wire strung across it, but the pilot could break past the wire to go to 'War Emergency Power' and gain anywhere from 15-50%+ more horsepower from the engine. The use had to be logged and after a few hours of this the engine would need to get a complete tear-down and rebuild. It is basically a 'you are trading away this engine to save your life' setting, but sometimes that was a necessary thing to do.
