So after talking with my buddy at a local shop (vivid) I told him i'd be in sometime next week to get the car dyno'd just to see what its putting out stock. He asked why not this week and I said I need to break the car in first. the usual 6-800 nothing over 5k deal and he said that they dont need to be broke in. He said that the piston rings are "made for boost" so if they dont see enough boost in the early stages of the motor they could possible not seat all the way. their certified mitsubishi master mechanic agreed.

Now i'm really confused, I dont know weather to do the normal break in, nothing over 5k for the first 6-800 miles, or should I not really worry about it and just take it fairly easy on the car(no rpm limit) for the first hundred or what?

thanks for the help in advance!

 

I would say DEFINANTLY NOTHING OVER THE 5K LIMIT!!! As you can see, every evo owner on this forum including me has gone easy on the car for 1k miles. Don't worry man, just keep it cool, you'll have fun once u break the evo in properly!!!!!

 

Highly discussed and debated topic. I don't want to sound like a *****, but search for it. There are a few threads dedicated to the "hard" break-in vs. the "soft" break-in. I personally, after going through the same deliberation, opted to go ahead and do like the manual said. Don't go over 5000 rpm for the first 500 miles, or something like that. But it can be argued either way.

 

Honestly, I believe the initial 'break-in' period for turbocharged cars is basically a psychological thing. You should be fine for a dyno test. But honestly, I don't really see the point of wasting the money unless you have some kind of mods done for your car. But hey, if you have the money, do it. My .02

 

I dont think you should worry too much about break in period. Just drive normal. I say, get your car use to boosting from the begining.

 

Do what the manual says. The car can see boost, even when being broken in properly. And the search button can link you to more of this very beat topic.

 

There are so many conflicting opinions on this issue. I can't imagine why taking it easy on a motor would be a bad idea for the first few hundred miles, I know I did. I also can't imagine what makes some rings made for boost and others not. They are just sized based on bore. You don't buy "turbo rings" for your Honda if you are going boosted so that makes no sense to me at all.

Its free thats why

Sorry for not searching. I view the site regularly and havnt seen anything of this sort thats why i didnt search.

Thanks for the replies. I think i'll do what the manual says and take it easy on it for the first couple hundred miles. Its has to be in there for a reason...

 

the evo deserves at least the owners manual break in period

 

Say what? Every owner? Anyone who "took it easy" for an entire 1k miles waited too long. I went to 500-600 miles without ragging the car out, but after that, I went *****-to-the-wall. The recommended break-in period is only 600 miles.

 

Dont abuse the car, drive it as you would any other. She will be fine. I would say dont redline the bugger under 500 miles for peace of mind. After that she will be fine. Its not like they blow up if you dont obey the manual and I have yet to see significant variances in HP with by the book break in vs. lead foot break in, its all the same.

 

You don't have to redline in a dyno for that long, it shouldn't hurt it if you've broken it in a bit, but I would do 600+ miles breaking in but that's just me

 

Drive your car like you are always going to drive it from the moment you get it.

It would be really nice if their was a 100% stern answer that everyone agreed on that would provide the best preformance/wear.

I dream a lot
