2009 Gtr Vs 2011 Gtr

[Martin Donnon]

Here is the raw data -

[domino_z]

that's great Martin, thanks for posting

so once ecu is remapped area under curve is pretty much the same

the 2011 has a stronger top end, could that be due to the larger turbo intake piping?

Same conclusion here. Once properly tuned they are almost the same.

[rehab2010]

AFR for 09 is unreal - almost completely linear.

[Col-GTSX]

wow, i was surprised to see there so close...

[Martin Donnon]

The two cars output is so close due to the fact that they have a mechanically identical engine package and turbochargers. The MY11 has fractionally larger inlet pipes which at this level of tune dont make a massive difference, but do account for some of the top end improvement

[fungoolie]

Wow, those results are so definitive. Very much the case of holding back something when first developed so you have something to market when the new model is released. We'll have to call it the new "Apple iGT-R" Based on this and the availability of the Cobb TCM software one would think we can get old and new GTRs launcing relatively similarly and giving identical acceleration figures.

Thank you very much for the data

Now I can stop thinking about wasting a pile of money on the new model.

My 2010 already has your full Ti Exhaust system and a bunch of other stuff.

Sounds to me like some of those 08, 09 & 10 GTR's that have popped up on the car sales website to upgrade, would be better off giving you a call and going to their local Willall/Cobb tuner and get updated mechanically for a truck load less $ than buying the new model.

Your detailed data makes me feel a whole lot better about my decision to keep my car and continue to upgrade it.

I also just ordered your splitter through Mercury and I think your turbo upgrade kit etc, is on the cards in the near future?

Thanks Kymbo

From our analysis the reason that the 2011 is quicker in magazine tests is not only its improved transmission software, but the ease with which you can put it into Launch Control mode. Many journos struggled getting their head around LC2 and simply bogged the car against the brake thinking it was in Launch mode...when in fact it wasnt. LC4 makes it easy for scribblers to actually get it right for once - hence the car road tests as a missile

so martin , according to the dyno there is about 10 ish kw difference . But carsales has this in their reviews -

"Despite a significant increase in output, now 390kW/612Nm against the predecessor's 357kW/588Nm, the GT-R is so tactile in delivering its mother-load that one would really need to be insensitive to such astounding figures to make a schemozzle of proceedings."

that's at 33kw difference , one car is either over stating or the other car is under stating.

[karma_syke]

so if you were planning on doing some mild modding ie; boost increase, exhaust, cams? and a tune, theres no real advantage getting the 2011 version,

[domino_z]

lol @ cams, it isnt an LS3

from that dyno graph, all you need is a midpipe and canned map

quite a few of us have already gone beyond that

love the tune'ability of these cars

they're quoting engine power. and again not sure if what they are quoting is 100% accurate.

thanks for sharing martin. 09s certainly are rich and the 11 is nearly a full point leaning right through the map. I guess the leaner tune, more midrange boost accounts for the power difference really. the 11 really has a nice hit of boost in the midrange which would certainly make it feel a hell of a lot faster too.

ultimate results are not surprising. they have the same hardware and once tuned the same 'software' so getting the same output is no surprise. again, thanks for posting.

[domino_z]

sending off my downpipes to HPC to get coated today

Martin my nagic number is 400.....what's it going to take? will my intake, inlet pipes, downpipes, midpipe, exhaust, dw 950injectors and tune going to cut it?

[Hazey]

Bit of a noob here and have a question regarding the launch control? Hope someone can set my mind at ease. Looking at getting a R35 but not sure on 09/10 vs MY11 - Was leaving toward the 11 due to the launch control being covered under warranty and not so hard on the transmission.

1) So is there a concern with transmission issues on a used 09/10 with launch control - does it void the warranty?

2) Can the software changes for launch control applied to MY11 be applied to MY09/10's

Thanks

[domino_z]

LC was discussed at length a while back here

cliff notes;

- 09 ADM build has LC1, but need to turn VDC-OFF, hence no warranty

-10 ADM build has LC2, but can be used with VDC-R and few hundred rpm lower, hence warranty

- 11 ADM build has LC3, but can be used with VDC-R with similar rev limit to 09 ADM, hence warranty

of course that warranty is all dependant on you leaving the car 100% stock, or lucking it up with a mod friendly dealer when something goes boom

if you wish to improve LC even further, cobb have that covered

http://cobbtuning.co...oducts/?id=5676

- ENHANCED LAUNCH CONTROL:Updates TCM to Nissan LC2 launch control logic with two user selectable launch control modes! Level 1 sets launch control revs to 3,300rpm (300 more than stock LC2) with more aggressive clutch engagement and throttle curve. Level 2 raises launch control revs to 3,700 rpm with the same clutch and throttle characteristics as Level 1.

imo LC is fun the first couple of times as a novelty when you first get the car, but as you begin to modifty the car, i dont find myself using it anymore or necessary to go quick off the line - save your tranny/drivetrain the stress and reduce the need for any repair bills

I don't think any ADM cars have LC1. might need to re-check that. I thought only the early 07/08 JDM cars had LC1? afaik the first aus cars were already LC2.

[Snowman]

Correct - it was only the few 08JDM imports that came in that had the LC1.

All Oz delivered cars had at least LC2 that you could launch without the VDC being off. The only warranty concerns were if you switched the VDC off - but you could launch all you liked.

[domino_z]

sorry Hazey i gotz those cliff notes wrong

either way, dont get too caught up in the warranty of using LC

if you have any shred of adrenaline or motoring enthusiasm in you, you wont keep this car stock with that pitiful electronic whine of an oem exhaust and limited by design 'apple iGTR'¹ factory power output

¹Fungoolie - pure geniusism

[Munro]

Its not "just" the power upgrade that I like about the 2011 model.

The interior is nicer, the suspension is smoother, the wheels look awesome,

and then there is the new colour.

Nothing wrong with the 09/10 models - never will be.

Just good to see the little tweaks have made it a better overall car than the previous one.
