Break-In Technique

has anybody read this??

i want to get others peoples opinion and if anyone has done it...

 

Long time ago and I have never done nor do I know anyone who has.

 

that's the way to doo

 

that's the way i'd do it.

 

Heard about this before, but I haven't seen the actual page.

 

whoa! I've never heard that before.

 

follow the manual, most new cars do not have a break in period but the evo does.

 

that's the way that we have broken in all our motors in our race bikes... proven hp! Don't know about a turbo car...

 

Thats the way I do it on all my cars also. Never a single problem, the evo's breakin is for the clutch.

 

I always hear one of two things:

a) keep it under 3000 RPM for the first 1000 miles
b) drive it like you stole it (your articles take)

...and really there is no telling the validity of one article from another...However, about a year and a half ago I found myself persuaded by this article (http://www.overboost.com/story.asp?id=1250)...It basically states the best of both worlds in that you keep yourself limited to 3000 RPMs, but you rev higher RPMS as you get closer to 1000 on the odometer...I dunno, read up...I think if any procedure is correct for a perfect break-in, it is probably from the article I posted...I would love to hear some input from the mechanics on the forum...

 

i drove it out of the lot with 3 miles on my odo, the first thing i did was red line it through 4th gear. and the Car's still pulling like a ****. Never had problems, I wanted to make sure the head was ok from the factory.. that's the excuse i used to driving it hard... -.-; well, after 11,000 miles, no problems, i'm gonna end up rebuilding it during summer any ways, so we'll see how the heads are during than.

 

Very controversial topic.

People swear by both methods. Im going to generalize here:

I think most people will agree that the method you posted in the link is the best way to break in rings, period. It will produce the most horsepower. Thus, this would seem to be the best way. HOWEVER, you must remember that every component of the car is being broken in during these first few miles. Though sealing the rings is important, there is a good argument to back up babying the rest of your engine and drivetrain during these crucial first steps.

On the cars I have owned I personally follow a balance between the two extremes. I usually baby it but rev the car to redline slowly in order to get a better ring seal.

 

I've heard from someone who's worked on bikes for quite a few years that He use to run His bike engines in by giving them a bit of a hard run. Apparently they went alot harder that way.

 

Well, ferrari and porche high end cars test their engines on high load before installing on their cars... so technically it's broken in the same way.

i've read about this method a long long time ago

 

I floored it the day i got the car

I never went above 5k until 600 miles though
