Proper break in (read any book on breaking in a new engine) requires at least a couple full throttle accelerations to max power (within max. safe rpm range) to properly seat the rings. The number one rule is to NEVER let it overheat.
Does Porsche dyno each engine? If they do I bet its been over 5000 rpm.
How do you break in a brand new Race engine? You floor it and don't let up. Note race engines have usually been dyno run for their "break in" period, usually very brief. Otherwise a couple of laps is enough.
