Hey guys, just looking for fast ways to break in the motor I heard of runing it on a dyno with load, going up and down hills, etc.
Any other ideas and how many KM's are good before final tune 1000-2000KM's

The sooner I break it in the soon I can get some dyno # !!!I can't wait to get this b**** done!!!!!!

 

Take your time. No need to rush, especially on brake in miles(km). The most important thing to do, is to let the rings seat. I'm in the same situation right now. Just be patient. The more miles, the better!

 

I waited tell I got around 2-3K miles before I did a tune at a higher boost on my built block. Did you do any valvetrain upgrades?

 

no valvetrain work, how often did you guys change your oil, and how much boost did you guys have during break in??

 

Keep boost to a minimum. Try not to go over 5000rpm, for the first 500 miles or so(what I've been told).

 

Does your shop/tuner have a load based dyno? If so, I would suggest doing the preliminary break-in (at least) on the dyno.

 

I change my oil regularly and if needed and My break in boost was set to 9psi

 

When my shop put the motor in they did the tune and put 500 miles on the dyno before I got it. Then I put another 2-3K miles on it.

 

1000miles for my motor b4 the tune was done, believe me...i was itching those 1000miles.....but its well worth the outcome......dont rush, and blow the motor!

 

Everyone has their own theory and technique...

I break my personal motors in by starting up and idling a few minutes, followed with an oil change. (Also change oil around 25 miles, 100, 500, 1000 - so maybe I'm obsessive?)

Then immediately to the dyno / street, ramping in power/rpm and allowing it to engine brake all the way back down on each pull. It is not uncommon for built engines to make 1000+hp within the first 30 minutes of life.

As I said, everyone has their own way and there are plenty of healthy motors that are broken in easy and plenty that are broken in hard. I am not advising one way or another, just putting something out there. In the end it is the owners job to evaluate the options and decide how they want to procede. I would also speak with your engine builder and see how the engine is setup and recommendations from them.

 

+1...I break-in my motors this way. If I don't have access to a dyno....I do it on the street....search mototune break-in. Some of you guys don't believe in this method. That's fine. You do it your way, I'll do it mine

 

dyno based break-ins r usually best and also quicker. Street break-ins introduces too many variables that disrupt proper breakage (ex. stop lights, traffic.. idle.. idle... idle... constant cruising speeds/highway where you're stuck at a certain RPM for a long duration of time)

 

+1. Broke-in my bike this way.....took 20 minutes.

i broke in my vg30dett using the mototune break in method and the engine has always ran perfect and still does but only have about 4k miles on it. Also I don't burn any oil or leak any.

 

I have gone both routes, jumping on the dyno immediately after 40-50 miles for some 600whp pulls, and putting over a thousand miles on first...have not seen any difference, but we still advise the latter ...not for any other reason than fear

 

I waited 1k miles.
