That's what I'd expect however the boost is regulated and kept below 6 1/4. There should be no danger of continuously running at that boost if revs are kept below 2850 which shall be the max continuous revs.

That's about what you find for the Merlin II engine. I prefer to run at 2600 because the sound is more comfortable.

Danger on engine lifetime comes from overboost when it's available and max revs, however the engine should handle it, only resulting in shorter maintenance and ultimately lifetime, but that's currently beyond Cliffs of Dover.
