This might be a really stupid question, but how many miles would a breaking in be for a 2011 X GSR? I was going too fast on the highway and I just feel like I'm abusing my car on a day to day basis. I only have like 650 miles on this thing...I've never launched nor will I ever to attempt off the track/strip. I keep putting it in high RPM's for no friggin' reason....

Am I delusional as hell or what?

 

First off, edit your post and remove what you said about speed, or I'll have to delete it.

Second off, yes that is abusing the car. High RPMs are fine, but don't be excessive.

There are two trains of thought. A) You need to be gentle with the car, keep it under 4k for 2k miles. Avoiding constant RPMs. B) Drive it like you stole it.

Mitsubishi does test the engines for x number of miles at the factory before they put it in the car. So the engine has been used a bit.

With my car, I was gentle with it for about 1200 miles. Then I progressively started driving it harder.

 

Done. Sorry.

So what am I to do now? I'm the type of person who needs things to be perfect...if I've ruined the future of my car I'm gonna be pretty sad...

 

dont worry about it. I would just keep on beating on it. I am sure some one already has. I used to work for a dealer. wont say which one but lets just say there was a lot of cold start full boost and redline events

 

Owners manual would be an excellent start for your engine break in. I bought my gsr with 22 miles on it, I am sure the dealer had fun with it and I havent had any major issues that weren't caused by myself. Don't worry so much and enjoy the car.

 

i have '07 z and i bought it new. the very first day i got i revved the snot out of it.. and ever since been driving it like it owes me money.. 51k miles later the vq35hr has proven to be a stout and great engine

my brother has a rx8 and he too did the same with his car when he bought it new.. 101k miles later his little rotary is still running around without a problem (sucks gas like crazy though lol)

my point is that all that breaking in stuff is bs

 

These comments make me feel better about my stupidity. I think I'm going to just cruise a bit and stay between 3K-4.5K RPM until like 1,200-1,500 just to be safe.

 

I'm a subscriber to break it in hard. From the dealership I warmed the car up and let it loose. No launches or hard braking, but I drove it like I stole it. Then the following day took it the auto-x.

 

 

I'm all for breaking in the car slowly. I waited until I was over 2k miles before I started opening it up a little. When I took my car to get tuned at RRE I only had a K&N drop in filter and they were able to get 316whp & 336lbstq out of her. I read a lot of guys with a full exhaust, intake, & a tune making the same numbers if not less on the same type of dyno (DynoPac). I'd like to attribute that to properly breaking in the car. Those other guys probably have lower numbers because they " drove it like they stole it" from the start, brand new. Then again, I'm not an expert & I could be wrong. But that's the only logical explanation I can think of.

Since you already pushed the car a little hard, I would suggest that u change the oil soon & then from now on just take it easy for a little bit

 

I'm in the camp of believers who basically say drive the car how you drive the car. I don't think you have anything at all to worry about. There are many engine builders who break their engines in on the dyno...and not gently! I know Honda took all their S2000 engines to redline before even dropping then in the car just to make sure everything was functioning properly to 9k RPM. There are many manufacturers who take one out of every certain number of cars to a test track just to verify it's hitting all the proper performance specs. I know quite of few guys who have driven directly from the dealer lot to a shop for mods/tuning too

I think the stock clutch break-in is of more concern than the engine to be honest.

 

I like answer B. Drive it like you stole it like that if something goes wrong you still have warrenty

 

And just for a sidenote:
All engines need to be broken in with "regular" oil......the Evo comes from the factory with synthetic, so they have done some break-in already

 

Just like any new plant, engine, or what have you. you have to precodition the engine/plant before you go up to High operating powers. The reason for this is that the components of your engine need to 'settle' in. The stress from pressure and temperature at normal operation will slowly precondition the material, this will actually strengthen the metal that is in your engine. (at first) The reason why you don't to beat your engine so much in the beginning of the engines life is that high temp and pressure produced may easily (microscopically) deform the internal components because they were not properly preconditioned. Its hard to explain cause I am no scientist but basically the NOP/T will expand the engine components to a point and then once the car is off the engine will slowly start forming 'memory'. Maybe I'll just freaking wiki this and you will have a more straight forward answer.

EDIT2:

A new engine is broken in by following specific driving guidelines during the first few hours of its use. The focus of breaking in an engine is on the contact between the piston rings of the engine and the cylinder wall. There is no universal preparation or set of instructions for breaking in an engine. Most importantly, experts disagree on whether it is better to start engines on high or low power to break them in. While there are still consequences to an unsuccessful break-in, they are harder to quantify on modern engines than on older models. People no longer break in the engines of their own vehicles after purchasing a car or motorcycle as the process is done in production.

After a quick glance, the engines main concern for breaking in are the pistons and cylinder walls. Cool.

EDIT3: Which then brings up the question, why is the recommendation in the owner's manual?

 

One of my guesses it's still called for is to give drivers a chance to settle in and get comfortable with the car and it's controls before going crazy with it. Maybe the clutch too.
