Recommendations on how the break-in a new engine

when i got my z, i drove it gently during the break in period.
later on, i got a (new) daily driver which had a much weaker engine and to keep up with the flow of traffic, i had to rev up the engine and change gear near the maximum rpm every time i drove it.
since doing this during the breaking in period didn't seem to hurt the dd at all, i don't think it would hurt the z either.

Your owners manual says wait 30 secs after you start your vehicle to let the oil flow through the engine. You can hear it when it has. After that let the engine warm up to temp then drive it however you want. Had plenty of new engines whether it's in a car, motorcycle, or pwc. I don't follow the break in process. Don't believe it. When new toys are out for testing, when reviewers test them, do they break it in before they get on it.......No. You may or may not want to hold it at full rpms for a long period of time but how can you do that anyways. I've been told the engine is usually broken in at the factory already or that it happens in the first 20 secs or 20 minutes or 20 miles something like that. I think you're good to go. Google Motomans engine break in myths if you want some subjective info.
