noooo just the limiter 
Yes, for less than a second. You could sit the engine on the limiter for a month non stop and it still wouldn't break.
I'd be willing to bet it would.

New engines dont need running in, its a well known fact to those with a good mechanical knowledge that running an engine in hard creates a better piston ring seal and always creates a more powerful engine as all the components that need bedding in will mate much better.
Also, 80% of the running in process is done in the first 20 miles of use, these are crucial and to be honest the best place to run an engine in is on a racetrack - as it gives the right combination of hard acceleration and engine braking to really make the piston rings work and seal properly.
Finally, all new engines are bench tested at the factory. This is where they are revved to the limiter in each gear to test they function correctly.
Lesson to be learned: If you buy a new car and want to get the best efficiency, economy and power output from it. run it in hard and do so in the first 20 miles. track days are great for this.

when i did a weeks work experience a few years back at a peugeot garage, they ragged the cars to within an inch of their lives on PDI's so when you recieve a new car its been ragged anyway, so no I can't see anything wrong there and I wouldn't run an engine in at all...

the engines are hot tested right next to me at work and i can confirm that the diesel engines get revved to 5k rpm from cold
makes a lot of noise

tis true, people say run them in hard and it gets a better seal around the rings ...
