Range of engine speeds during break in

If I stay between 1.8-2.5k during break in period. Is that okay? Or do I have to go through the whole range of 0-5.5k rpm?

I would not limit it to 2.5k. C'mon, that's not much above idle. I don't think you necessarily HAVE to go through the whole range up to 5.5k, but you need to actually break it in. 2.5 ain't gonna do it. I was pretty easy on it the first couple hundred, then worked it a little higher now and again. It's at just over 1000 now and I have been right up to 5k at a little over half throttle a few times this week, only after it is fully warmed up. I consider this to be babying it. Next week, over 1200 miles and I will start working it over 5.5k, gradually working up to redline and WOT somewhere between 2k and 3k miles.

the most important part is that you are varying the loads on the engine. as mystic said, 2.5k isn't going to cut it. i would just say drive it like you normally would, but keep the revs under 5.5k. you want to do both slow cruising and quick acceleration to help the bearings and other components find their place in the engine.

Go through whole range up to 5500 rpm. After 1200 mile service start bringing your maximum revs up a little bit each week until you finally bring it up to red-line by 3000 miles.

Use the full range - fast, slow, different load points, etc.
