Break-In Method
i didnt go past 50% throttle or 4500 rpms for the first 250 miles. after that i took it wot a couple times, then at about 750 miles i was doin wot pulls very often. 37k miles, running fine.
I hopes this clear things up about engine break-in period. The Motoman break-in precedures are ONLY for engines that has just been rebuilt. You want the rings to "seat-in" properly for better seal. Now all the companies out there that produces car engines all ready knows this and they already put their engines on a engine dyno to do such that....to have all the internals seat in properly before installing it on the car. Then after installing it in the car, they put the car on a regular dyno to check both engine and drivetrain. After they drive in onto the barge on container to be shipped around the country. Now if you think about it, there is already a little mileage on the motor coming from the engine dyno, regular dyno and the distance they put from the carrier to the barge. Follow the manufactures break in period, they know better.

When I got my STi back in 2005 it was brand new. I was told by the Subaru dealer not to take it above 4,000RPM's for the first 1,000 miles. I tried my best, but on the first night I had the car, me and my buddy had it going 135 at the top of 5th gear. 24,000 miles later, car is still fine.
I will probably be more conservative with my Evo though. Every now and then go WOT, but drive it conservatively until it is broken in and tuned.
