Ok 606, enlighten me, what is it that is used in the Honda S2000's? "These same break in techniques apply to both steel cylinders and Nikasil, as well as the ceramic composite cylinders that Yamaha uses in it's motorcycles and snowmobiles"

 

So, any comments?

Anyone think the article is waay off or is it spot on?

I broke my car in gradually and put 210.3 to the wheels, so maybe I should just redo the same with my next car!!! Maybe it had nothing to do with it and I was just lucky.

I am confused now!!!!!!

WAAYYYYYY off. Read all the way to the end. IMO this article is simply a means of stirring the hornet's nest to create an interest in this guy's magazine. All this website has is masterful marketing.

 

Ok, if you state an opinion, back it up with fact. Everything he says makes sense. Can you dispute what he says?

I do not agree with his claim. Everything he says does not make sense, nor is it a fact. Let's get one thing clear: just because some guy has used this break-in method on "over 300 engines," that doesn't mean it is the correct way to break in an engine or any engine. There are plenty of people who break-in their brand new cars in many different ways without consequence. Not all engines cylinder walls are honed with a crosshatch to file down the piston rings.

Unless this guy is unable to properly translate his thoughts into words, this makes no sense.

There's a little more than aerodynamic drag the prevents a car from freely rolling around, especially at lower speeds. This guy is brilliant.

 

I'm not one to believe what I read on the net blindly. But what this guy says in his article has been argued by many people, especially people in the racing seen. The argument against the people in the racing seen has been that they do not care about longevity and a race engine gets rebuilt frequently so a gradual break-in doesn't apply...

I am not sure, and my knowledge isn't enough in this area to be able to come up with a conclusion.

I find this subject intersting though, and I want to hear as many opinions on it as possible.

 

Piston speed determines wear. WOT builds high cylinder pressures, but pushing out on the rings? If this was true, then lugging an engine would grind the rings right off. This must be why diesels have such short lives.
The reality is that modern machinery allows closer tolerances to the design and therefore you can run harder, earlier. In the old days high spots had to be polished off slowly, and short drives coupled with cool down periods were required to prevent seizing from overheating. Better oils also help here.

Racing is a different thing. When you hand build and blueprint an engine, the tolerances of mass production are eliminated. The factory does not plastiguage each bearing, match each valve spring. and hand torque each fastener, then turn over the engine by hand to feel for smoothness. Even so, race engines need a little run in before they are run hard. Not 10,000 miles or we would never see a race. I felt the S motor loosen up for the first 1200 miles, but after that is is probably minimal. I am sure this varies from car to car, but this is a jewel of a motor. I am always gentle with a new motor because I am paying for it. I am sure those 300 motors he thrashed weren't all his.

 

Blake...don't get me wrong. I agree that ANY opinion should be backed up with fact; however, instead of asking me I think you should ask "Motoman." Where exactly is the fact/proof on his website? Where are the before and after dyno charts for all 300+ supposed cars that he has performed this break-in process on? Oh wait...I forgot...you have to order his magazine to find out. I definitely won't agree with you that "everything he says makes sense."

Here are a few examples:

No thanks Motoman.

Why not post at least one Motoman so people can decide if "they want to order."

Of course it's provocative stuff. That is exactly what sells in this country.

Ok...first and foremost like I stated earlier this is all MARKETING. The guy is trying to sell his "Power News." Also, what is the point in us even debating this subject considering EVERYTHING he says applies to a car/bike/lawnmower( ) in their first 20 miles. I think everyone here has twenty or more miles on their car, so we are all already SOL if this crap was even remotely true.
