Controversial engine break-in method

LaSeeno · 03-16-2010, 04:01 PM

Here's the article I read about 5 years ago. I believe this was written for street bikes but the mechanics are the same for automobile engines.

Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power

I have no idea about real world testing but this is the way I broke in the 46G3 stroker I built and it had perfect compression and held plenty of boost.

I cannot imagine that Nissan hasn't already "broken in" these engines from the factory. How else would they do QC checks?

Ooohh, it's been a while since we've had a break-in thread. Break-in threads are almost as fun as oil threads!

Lol. There is a search feature on this forum...

I've seen shows on the ol' TV where they build a motor, put it on a bike, fill it up, and get it on a dyno and just run it hard for an hour. Done! lol

Not again!

lets just all agree that the second you drive off the lot, keep it redlined for the first 5000 miles.

done?

done.

Everyone's an expert on this....Just ask..

lol... there is a reason you break in a performance race car on a dyno... with that said... you are not probably going to see any difference in power from doing this one way or another... at-least not enough that it would be mainstream by now... Me personally - I almost followed the motoman directions completely with the addition of many many oil changes in between the miles... to each their own

i like the article. would like to see it in person before I sign off on it, I break in all my dirtbikes this way but when I rebuild my motors they are not quite that clean but know where near that dirty. Hmmm lots of thinking going on.

Just look at page 5-22 with a big CAUTION in your 370Z Owner's Manual.
