Engine Break in secrets...
Discussion
Personally I'd be much happier taking the advice of the chaps that made and know the engine, and therefore go for the 'easy break-in'. As opposed to taking the advice of some bloke that just happens to own a website...
I have to say then when I first saw the topic heading, I thought this was going to be a 'how do I get into a locked car and start it-type effort. Thankbloodygoodness it isn't

...he's showing motorbike engine pistons, no torque and high rpms... different ball game, if he's succeeded in making a difference there then good luck to him and his followers... but a new engine needs to expand and contract many times before things are bedded in, the ring sealing is a good argument, but go dry sump with vacuum and you start off with a good seal, so I dont know what he's on about poor ring sealing - although depending on what rings and liners are being used etc etc...
If for years you've been told not to put your hand in fire because you'll catch fire, and then someone one day comes along and says its ok to put your hands in fire, your hands will burn, but you'll survive (and heres my neighbours dog who did it for living proof) - will you do it????
Exactly.

Interesting. I just don't have the heart to thrash my very expensive pride and joy from new so I've meticulously run in every car I've ever had.
Only evidence in favour of this guy's theory is that many new cars have crappy oil in them to allow a degree of engine wear that the ultra slick synthetics won't. My honda s2000 was one. They actually recommended not putting fully synthetic oil in for the first few thousand miles.
The other evidence is race engines. They are never run in. I can only imagine that they would be if there was a significant power advantage. That said, they may have some bench running in programme before being put in a car. But I don't think they do.
Also most modern cars are tested for horse power (eg ferrari and porsche) so that each engine can be guaranteed to produce a minimum amount of power before going into a car. That of course means running them flat out for power readings.
BMW owners seem to love thrashing from cold. They now have warning lights to try and stop them doing this. I can only imagine it was becoming a warranty issue. I've also seen many a brand new ferrari being thrashed stone cold and brand new away from Maranello's in egham. I guess with most being sold with only a few thousand miles they haven't got time to waste. But it always looks and sounds really cruel!
I wonder if there will ever be a definitive answer to this age old debate?

But full-on race engines will be pretty close to blueprint engines and will probably also be stripped and rebuilt at the end of each race...

Apparently Porsche do not recomend stationary warming up but in fact encourage start up and immediate drive off (though not neccessarily thrashing it)
This was discussed recently and the general consensus was that stationary idling/warming puts undue strain on an engine. Much better to have it pulling under load.

this is hardly controvertial. It's a fact known by anyone who races cars/bikes.
It definately gets you more power. But I too would never do it on my trevor...bottom line is I do what the factory says for warranty reasons, etc.
For your regular car on the street I would definately do it though. It can make a big difference. I remember some car mag testing this with some new hatchback or other ages ago. damned if I can remember where now though.

I thought most modern engines were run in on the bench now before they even see a road?
When I used to work for a car dealership we used to cane the demo cars from day 1 and they certainly benefited for it, not sure how long they lasted after that they were always gone to new homes by 3000miles
