Alot of ways but this is interesting. Input plz ChinG http://www.mototuneusa.com/break_in_secrets.htm
Yeah, I read this a couple of years ago. This makes sense for a race engine and/or a motorcycle engine that will run 20-40k miles. I dont know how this would work on a car engine. Especially a new cars that track all of your break in procedures...
If you could break a car in on a dyno at load this quickly, and it did what he said it did, manufacturers would do it to reduce warranty claims.
I agree there is SOME truth to that, BUT. Longevity is key for cars. Race bikes will never see more than 10k miles on them, and that's what he's talking about.
i have some friends that when they finish a motor they run it hard or break it in on the dyno. these are hondas not subarus though. lol works for them
I have broke in my engines in a way close to that. It is not as agressive. However, I change the oil on the car a couple times during that. This spring I will being doing my first break-in on a turbo motor. Not sure if I should change something up. Not sure if I want the little metal stuff from break-in getting into my turbo seals.
I think I'll go by what professional engine builders like Ron at RAW say. It has worked well on the two subaru motors I have put together thus far. http://www.raw1performance.com/index_files/Page1229.html
First 500 miles I take it super easy, no boost then to 1200 miles I give it a little more with some boost but keep it under 4500 rpms This has worked great for all the motors I have built in the past from Xgames rally car motors, to just normal street car motors. Now my new car on the other hand, Its still close to 4500 :laugh: NOTE!!! this picture was taken on the Autobahn in Germany, I am not that stupid to go that fast on our freeways
