No break-in period for GT-R motors?

[BoxsterSforsale]

Just read on Nissans GT-R web site that the cars will be delivered with the motors fully broken-in.
during track testing: "in a mere 27 Kilometers, fully break in the engine".
as well as seat in the break pads etc.

That's the first car I ever heard of that didn"t call for a least 500 miles of break in time...

If so, I can't wait to burn rubber out of the dealer parking lot!!!
(after the engine warms up of course)

[Ev0H8t3r]

I have heard the same thing...but I would still be careful the first 500-1000 miles...you never know! Murpheys law and always that 10%...

[JaredPink]

Yea, but full factory warranty.. =) Burn rubber outta the lot, and have the wrecker bring it back 50minutes later for that new engine... I imagine Nissan will go way out of their way if any major repairs are required on these beasts.

[Ev0H8t3r]

HAHA Jared your funny...
but who wants to be months away form their GT-R!!
I mean man we have waitied so long to finally get one, why ruin the moment;)
I'll take care of mine...LOL...only when the wife and kids are in the car!!

off topic...Funny, i saw my wife researching the GTR onlin eon some Japanese Websites...Out of all the sports cars i have owned this is the 1st she has ever looked up and did research on...Glad to have her support;) I know ooff topic...

[JaredPink]

My wife would tear up the 89 Supra... my favorite moment with her in the car, was when I made a hard right turn and matted it, laid the rear out and created a TON of tire smoke, followed with "Man I love doing that" from the passenger seat I hear "Me too!"

Back on topic though, the motors are fully broken in, so it's go and have fun from the get go!

[Ev0H8t3r]

lol!

yeah well I get my car here in Korea prior to them opening their GT-R Service shops, Im screwed!! I need to be somewhat careful...My wifes friend looked at me and asked me "what are gonna do with a car like that here in Korea" I luaghed...well 2am there is no one on the roads! plus there are some sick mountain loops and rides here! looking to taking those hard fast turns!

my wife already knows...HEHE Im so bad!

[JeremyBlackwell]

This is a smart move on Nissan's part! Most people will be wide open with the car as soon as they leave the dealership, so this will reduce warranty claims and increase product reliability.

[AdamSupra]

I agree... EXTREMELY SMART move on Nissan's part. It seems like they are doing everything possible for this car.

Still gonna let the piston rings seat for a few miles. ;) Variable drive speeds and gearing, and plenty of downshifts. I prefer to massage the engine into it's powerband. It'll be interesting to see what the owner's manual says about break-in if any.

[ATL-Porsche]

I'm going to use launch control, right after I leave the dealer's lot. j/k (well, kind of) :)

haha!:D

Go ahead.....:rolleyes:

[scarface]

I thought that all modern day cars were run-in at the factory... it was only in the old days that you had to run them in a nd service them after 500 miles!

[Ev0H8t3r]

well even if there is no break in req. accoirding to Nissan they want you to bring the GTR in to the shop after 500-600Km...

[UAE-GTR]

LoL you wont do it, that car it just cost you $$$ you know what i mean .;)

[Cucuy]

Ill still baby it around for a while. then ill start smashin. But if I find some one to line up with me once out of the deal. You know damn well I'm gonna run....

[RRnold]

Take a look at this and around the 2:15 mark, you can see them being broken in on dyno

"According to the the Japanese owners manual, the GT-R has a 2000km break in period with some specific instructions on driving and even braking during those first 2000km."

[Phoenix]

When was the last time you bought a new car:confused:;)

[blockbuster]

I would not hesitate to wind it up to the redline right away but I would avoid sustained high revs for long periods of time for the first 600 miles or so. This may just be habit but it is probably a good idea even with modern engines. And, it is not inconvenient (unless you plan to take the car on the track during the first couple of weeks).

[Phoenix]

Apparently the JDM manual says something to the effect of:

"first 500km <3000rpm
next 500km <4000rpm
considered broken in but first service asap". (per 'tokyogtr')



This is not directly relevant, but:
Any motor I have had 'fully-built',...lots of metro driving at variant speed, variant rpm, with downshifting so the engine wears evenly on the upswing as well as the downswing. I guess I may be a little anal about such things:o I just want maximum longevity from the engine.

[Ev0H8t3r]

I can't remember what website or where i read the break in instruction for the JDM R-35, I will find it and I will translate...

[Ev0H8t3r]

Since I am at work on a government PC, the encoding is all jacked up and the Japanese is all in CODE and script and I am unable to read anything on there. I am unable to translate anything at the moment, but it any of you read Japanese here you go. If you can wait for the info I will do it when I get home…

http://www2.nissan.co.jp/GT-R/R35/0710/index.html

CLICK on TAB 6, then click on the THIRD min-tab NISSAN GT-R maintenance.

You can find all the information there about the break in period and care of the R-35.

That holds true for any new motor and seating the rings. Don't redline the piss out of it but just as long as you keep the engine "loaded" and don't let it bog in the lower gears.

[mc]

yeah nissan standard break in is under 4K for 1200 miles. i did this with both my 2003 Z and my 2007 NISMO Z.

but i swore i read somewhere the VR was redlined for 10hours before it went into the car.

also in the GTR presskit there is a lap by lap break down of the break in they do at the factory test track

Anybody going to do the Mototune method?

Did it on all my bikes, and all of my 600's loved to rev to 15K! :D

http://www.mototuneusa.com/break_in_secrets.htm

[Phoenix]

On the Street:
Warm the engine up completely:
"The best method is to alternate between short bursts of hard acceleration and deceleration. You don't have to go over 65 mph / 104 kph to properly load the rings.

The biggest problem with breaking your engine in on the street (besides police) is if you ride the bike on the freeway (too little throttle = not enough pressure on the rings) or if you get stuck in slow city traffic. For the first 200 miles or so, get out into the country where you can vary the speed more
and run it through the gears !

Remember that both hard acceleration and hard engine braking (deceleration) are equally important during the break in process."

I used to always go out late at night on surface streets with some street lights to help simulate some of the up and down. Accelerate and decelerate with the same intensity on the engine; i.e. always downshift. Let it power up and down through the powerband of each gear, but like the advice in the dyno break-in, I did 50% throttle for the first few streets, working up to 75 - 85% throttle about 10 minutes into the drive. After the engine had been hot for awhile (180 - 185 fahrenheit (82 - 85 celsius for 20 minutes), I would get on it a little more. The worst thing is to drive at constant speed and throttle. Lots of variation.

Yes, exactly!

I know on motorcycle engines, they love to rev 0-15K on I4 and 10-12 on V-twins so proper break in is essential.

I know a lot of engines are tested prior to leaving the factor and if not all motorcycle engines come with a semi synthetic specific break in oil.

With 0 miles on the clock, I would dump the OE oil in place of some Shella Rotella, non energy conservation dyno oil because of the wet sump clutch. Load the engine for a good 25 miles then change it. By the 25th mile, the oil is already black and filled small shavings. I'd wait until the 150 mark, then dump it again @ 300, 600 so on. @ the 600 mile mark, the bike was ready to go. My last race bike ran very smooth and made 118HP; not bad for a 600 on U4 race gas w/a full exhaust system, modded airbox, piggyback on custom map!

[davett]

Guess I'm old school on this one, I've always used the factory recommended break in guide lines, worked so far. Besides going easy the 1st 1500 - 2k miles gives you time to get use to all the new toys :p

[Ev0H8t3r]

Well, the GT-R is a easy car to drive, however it takes some time to get use too. my buddy is not having fun with his GT-R yet, he has owned it for about 2 weeks now and he says its like buying a new vidoe game for the PS3, it takes some time to know what you are doing...

so i think by the time we all hit 1.5K-2K we should know what we are doing :)

[bcneil]

I think I might take it to the dragstrip the first week just to be the first one to do it. As in Vancouver I don't think a lot of the guys waiting to get theirs will ever take them out there. Seems like it shouldn't take much getting use to this car to run consistent 1/4 miles

[mc]

im autoXing mine probably by our July event if it indeed arrives the first week in july if not then it will be august

[mcwop23]

I was never a big believer in the 500-1000 mile "babying" the engine. I was redlining my evo at 300 miles and it's pretty much a freak car power-wise.

[Ricky Ricer]

I have a friend who never even broke in his STI. Redlined from day one, and he put down the most WHP at altitude for a stock STI.

As for the GTR, the screen shot posted earlier is only what Nissan does to make sure everything is okay with the car prior to shipping it off. I believe there is still a factory recommended break-in period.

[Myutahgtr]

Why is that?

[Ev0H8t3r]

Wel it is offical no break in needed, but I will break it in, no need on throwing $70K down the drain!

[stick]

I would also still break in the motor, with plenty of oil changes during the process.

[doors]

So if engine is already broken-in, can the oil then be change right away to a 100% synthetic grade. If so, what would that grade be : 5W 30 ? Or, would a engine of this kind already come with 100% synthetic grade ?? thaks for any answers in advance ...

Just read on Nissans GT-R web site that the cars will be delivered with the motors fully broken-in.

Because of the plasma sprayed cylinder bores, Nissan specifies that you can only use 0w-40 motor oil. I would go by what they say until there is enough data to determine if a different weight oil could be beneficial...

[Ruppie]

They are also ran for 10 minutes at 7,000 rpm in the shop right after the motor is put together by the 1 man working on each engine

What is your source for this information?

[JeremyBlackwell]

Just spoke with Ruppie on the phone, and the GT-R brochure he has from Nissan states that what he said is a fact. He is supposed to post up a picture. The main reason I was questioning the statement was that I was under the assumption he meant 7000rpm for 10 minutes UNDER LOAD (and boost!) However, it is with no load/boost. So, that isn't something I wouldn't question :)

[mc]

just got off the phone with someone at the dealer training event in vegas 5 mins ago

around 60 miles will be on the car at delivery and a 1K break in is required

[winsome]

It stated very clearly in the owners manuel that no full throttle and only half throttle with no more than 3500rpm for the first 500km. From that onward until 2000km NO rapid acceleration on the first three gears and remember also to avoid bumpy roads. Set to Comfort on suspension setting for more travel. Section5-32 So the car needs until 2000km to be consider broken in. Lets put it this way....easy on your foot until 2000km......

[mrplatinum]

better safe than sorry why play with fire

[Ra3y_Datsun]

I did 1200 miles break in and until now i did not push it to the limit. Almost now 2200 m. better to do some break in as usual to any new car.

[Norman]

not the engine needs to break in,the whole chasis,suspension system,rubbers,cats&silencer inner material,transmission,LSD,expensive disc rotor,brake pad,power steering and much much more.......even your BOSE sound system......need to break in too,think about that.

[Norman]

ps.if i a a workshop owner then i will told you guys "THIS CAR NO NEED TO BREAK IN!"^^:

[gschoonover]

Guys, From the 2009 NISSAN GT-R owner's manual page 5-32:
Please observe the following types of driving until the mileage shown below has been reached.

Until 300 miles (500 km):
. Do not depress the accelerator pedal more than halfway and avoid rapid acceleration.
. Drive with the engine speed kept at less than 3,500 RPM.
. Avoid unnecessary quick steering, abrupt braking and driving on poor roads.

300 to 1,200 miles (500 to 2,000 km)
. Avoid rapid acceleration in a low gear (1st to 3rd gears) with the accelerator pedal fully depressed. Depress the pedal slowly.
. Avoid unnecessary quick steering and abrupt braking.
. Drive with the suspension setup switch in the COMF mode to allow more suspension stroke.

[V8_Club]

. Drive with the engine speed kept at less than 3,500 RPM.


What about Vehicle Speed ? Also does it matter what type of miles ? i.e. Highway vs. City Traffic ?

[gschoonover]

What about Vehicle Speed ? Also does it matter what type of miles ? i.e. Highway vs. City Traffic ?

No limitations on speed (just RPM up to 300 miles).
No recommendations on type of driving.

[V8_Club]

Thank you sir. Will stick to above like GLUE :D

[ghall]

what is the Mototune method?

[daytonaman675]

I have used the mototune method on every new gas powed toy I have, it works.

@ghall the mototune method is an engine load method that seals the piston rings in a more effective way. It uses varied RPM/LOAD/Engine breaking methods to make a better ring seal and by having a better ring seal more power.

From memory (subject to foggy spots/missing info)

first stage is 40-60% of your engines max RPM under 45-75% throttle.

second is 50-80% Max RPM under 50-80% throttle.

Then I add in a easy run up through the gears taking it to 1k before redline in each gear (1-4 highway 1-5 at the airport) call it a 60% throttle and then engine breaking back down through the gears. (at the airport I use the 6k ft taxi way not the main runway)
I then change the oil and follow the normal 500m breakin of not over 5k rpm or 70% throttle. This alows me the chance to get used to the car/bike and for other items to get some wear/bedding in before I go smack the dog piss out of it. :)

[johnnyplatnum]

My 2009 Us model had 24 miles on delivery. This same issue occured with my twin-turbo 2001 Audi S4. Audi claimed factory break-in and discussion regarding both the gentle way of breaking in the car as well as the superbike derived method. There was much speculation and investigation done.

The superbike method where abrupt full-throttle accleration followed by applying engine braking was disscounted as not being relivant due too differances in motorcycle and automotive engineering, build quality and differant nature of 2 vs 4 stroke engines. 2 stroke engines are much less technical than are automotive engines, especially these high-performance, twin-turbos.

In the end it was concluded prudent to not rev engine too high RPM or use full throttle for first 500 or 1000 miles. I agree with the reasoning here and plan on babying my GTR in it's first miles and delve into it's performance gradually. Also stop-and-go driving or driving short trips was considered harmful to the brand new cars.

My dealer also presented paperwork for signature that I would agree to factory recommended break-in period.
