KNOWLEDGE = POWER.
This is a very controversial topic.
I wrote "Break-In Secrets" after successfully applying this method
to approximately 300 new engines, all without any problems whatsoever.
Links to this article now appear on hundreds of motorsports discussion forums from all over the world. The reason is that over time, large numbers of people have done a direct comparison between my method and the owner's manual method, and the news of their success is spreading rapidly.
The results are always the same. a dramatic increase in power at all RPMs. In addition, many professional mechanics have disassembled engines that have used this method, to find that the condition of the engine is much better t han when the owner's manual break-in method has been used.
The thing that makes this page so controversial is that there have been many other break-in articles
the past which will contradict what has been written here.
Several factors make the older information on break-in obsolete.
The biggest factor is that engine manufacturers now use a much finer honing pattern in the cylinders than they once did. This in turn changes the break-in requirements, because as you're about to learn, the window of opportunity for achieving an exceptional ring seal is much smaller with
newer engines than it was with the older "rough honed" engines.
In addition, there is a lot less heat build up in the cylinders from ring friction
due to the finer honing pattern used in modern engines.
The other factors that have changed are the vastly improved metal casting and machining
technologies which are now used. This means that the "wearing in" of the new parts
involves significantly less friction and actual wear than it did in the distant past.
