"interesting" site on engine break in
sounds like he's full of it to me. I can't imagine this would benefit an S2000 to do this.
opinions? technical responses?

This has been discussed many times. I go with a method similar to motoman's and have had great success.
Search the site, and you'll see this debated ad nasuem. It's your car, so break it in the way you want. You'll get people on both sides of the fence and those in the middle.

Wisconsin,
We broke in our race engine on the dyno for about 20 miles, then started tuning and it had less than 100 miles on it when it did its first race. Oil is spotless and no oil consumption whatsoever. Bottom end is totally stock - every part - just blueprinted.
I think I'm going to beat on my next new engine and see what happens. I think that in the long run it'll wear out a little quicker, but hey, I want to have fun now!!

You know I'm sorry but this is going to be harsh but I'm just getting tired of seeing such unreliable information posted so repeatedly. This gets posted at least once every couple of months and i would expect that someone who has been here 3+ years would have seen this many many times before. Search please.
The techniques that he uses are completely unscientific. The methods he uses to present his 'arguments' have been used by con artists for mellennia. If you trust anything he says as being accurate or reliable then you are making a HUGE mistake. That's not to say there may be something to a hard breaking but the gain will be minimal and the risks are real.
Here's prior discussion on this.....

I'm sorry if this is a bit harsh, but I hate to see people put any faith in these types of articles. He doesn't present scientific data to support his conclusion, plus he completely ignores the risks of hard break in. The worst thing about these types or articles is that there are people out there who take them at face value without questioning them. I feel really sorry for those people, because eventually someone will break an engine doing this and they may get warranty denied. That person would get screwed for trusting in someone that they should have NEVER trusted. The author of the article has limited credibility and you shouldn't trust what he says. You are taking a risk for little to no gain.

I don't know if it is true or not but I bought my S2000 with only a few miles from a respected dealership where i highly doubt they raced it or drove it hard and then for the next 1,000 miles i babied that car as much as I could and did EVERYTHING i was supposed to. THe car now has 15,000 miles and i dynoed it to come out to be only 181 rwhp. That to me is pityfull. Most S2000's I've seen have way more than that so I don't have any reason to believe that the factory break in reccomendations are correct and if I were to buy a new car i would try running it hard out the dealership and then driving easy for the next 1,000.

The problem is almost 100% with the dyno not the car....did you happen to dyno on a mustang dyno if so your numbers are completly consitent with a stock s2000. The type of dyno and the conditions under which is was run play a HUGE factor in the reported output.
I've always been a believer in running a car "hard" from new. I hit VTEC in my S2000 after maybe 40 miles, and redlined it after 200.
Never had any issues in regards to oil consumption (ie: no measureable amount has been burned). I also switched to Mobil 1 after 3,000 miles (which apparently is a big "no-no" around here.
My previous S2000 had 10,000 miles on it when I purchased it. It was broken in according to the manual, and was consuming approx. 1 litre of oil every 3,000 miles.

you have a MY04 almost no MY04 burns oil....that comparison is meaningless....
