its basically for superbikes, but it also relates to cars. check it out tell me what you think.

 

While I have heard this theory before and there is a certain amount of truth to it, it is not the whole story.

First off the F20 engine uses a different type of cylinder wall material that this article does not take into account. It is a carbon fiber/metalic/ceramic mix that may or may not react exactly the same.

There are high spots on the rings and other parts that need to wear in in an easier manner otherwise they will get overheated.

Until the rings make total contact with the cylinder wall the piston loses some of it's ability to shed heat. As the piston only comes in contact with the liquid cooled block via the rings/cylinder wall contact this can cause problems with the pistons overheating. Keeping the pistons cool is a priority with an engine with such a high specific output. That is why Honda makes sure they get sufficient oil spray cooling on the undersides via the oil jet bolt upgrade. Running the engine hard before the rings are making good contact is not advisable IMHO.

Honda knows their own engines. They are using a a break-in oil to help bed the rings in and they know what temps they want to keep everything for the first 600 miles. I broke my engine in by the book and when I had my spark plug recall done I had the compression checked. My cylinders were 225,226,227,&230 which is excellent. The Car does not burn a drop of oil. When I had the oil bolt upgrade done my mechanic said the internals were as clean as if it were brand new (it is 3 years old). It would not look that way if you were getting blow-by past the rings.

So do what you want but I went by the book and got excellent results.

 

very interesting...

 

yea bieg true.
