Rumor or truth?

[ATLsupra]

There are some rumors saying that US version of the GT-R will be having less horsepower (460hp) due to fitting with lower grade gasoline sold in some states (mainly you California folks! :D ) and the car will have a softer transmission (different gears to fixed whines) and softer suspension. How do you feel about this?

Personally I really hope this is just rumor. It sucks to see a great car getting de-tuned.

I hope it's just a rumour for everybody concerned, if not, I hope a similar thing dosn't happen to GT-R's heading to Australia in 2009 !!! softer suspension might be a plus though for our very common rough roads...

It's not uncommon though for specific changes in tune, suspension and chassis to be carried out to suit different markets...

I know for eg: the USDM Evo 10 has chassis alterations which add around 100lb of extra weight...

The fuel issue tune thing could very well be required to safeguard against engine damage...

From what I've read regarding the GT-R's suspension, a lighter/softer tune would probably be welcome and hopefully shouldn't negate any of the cars handling qualities...

Softer trans - don't know about that one, if this means it can only handle less power and slower shifts, damn definitely don't want that !!!!

Hopefully in time, all manner of tuning will be available, so if it is curtailed in any way, you'll be able to bring it back to full whack or tune it up even further, I think most R35 GT-R owners will want to do that :)

I remember hearing 480HP for some reason...?

Well im sure as we know, it will be able to overcome its just a matter of how much it will cost to modify, how hard, ecu tuning etc.

Guess we will just have to find out.

When I ordered mine, the dealer provided specs and it did read 480hp, not 460. As for the CA thing, I'm not sure since I'm located in GA.

[LaNissanDealer]

according to everthing I have seen and official data from Nissan, the rating is 480 hp

[LAWLESS]

you will never know until it touches our streets

True, we'll never know until it arrives. I have a hunch that Nissan underrated the power and it's actually more than 480hp according to what I've read and seen other dyno's from Japan on other boards. (i.e. tested by Edmunds GT-R does 0-60 in 3.3, Nissan states 3.5). I think we'll be pleasantly surprised. Car is too heavy to go as fast as it does w/ the manufacturer stated horsepower...

Voted not true.

and if it is, we have this little thing called remapping the engine via software. ahhthankyou

Most defintely NOT true -- US specs are clearly posted on Nissan's GT-R site.

480 is the number

I have a hunch it's actually higher than 480... We'll find out soon enough

Dynos will be all over the place depending on the dyno make and method. What's interesting though is that we're going to see an average dyno at the wheels at 480. I don't know of any other case where a car manufacturer put at the wheel specs out instead of at the crank. At the crank (for comparison to other manufacturers) she'll be pushing around 520 on average.

For the horsepower issue I believe that 480ps is listed in Nissan USA site is still based on Japanese specs. Now, for the US or Canada for that matter the final figures should be 473hp since we are based upon a different measuring system. (SAE)
For most people who has some knowledge about the 350Z when it first came out is actually quite interesting. Cause back in 03 the Japanese spec 350Z has 280ps. where as here in N.A. we have 287hp Now I was under the impression that the N.A. specs has more hp until the later HR series became available which in Japan specs has 313ps where as we are siting at 306hp (which is essentially the same power iterated by different measuring units ie, Australia Kw vs USA hp)
Not to mention I've read from another GTR site that Jspec.com imported RHD Black GTR has been on the dyno and it actually did 460whp. which means it actually has more crank hp then Nissan has posted
As for 350Z owner knows, that 03 model 287(Crank hp) is actually more like 225~235whp Now, think about this, the Z has rear wheel drivetrain which technically should have less Tranfer loss than a much more complex and sophisticated AWD (ATTESA E-TS) equipped GTR?
To me I honestly think that it actually is more closer to 520~530ps (at the crank) Which is amazing! Now why Nissan posted a underrated hp figures I don't know. But for sure as hell it will not be anywhere less than 473hp when it hit our shore officially.

Since when was OEM power out of the box a concern? Every serious GT-R fan will at least go "BPU" with this thing. So in my opinion, i think stock power is irrelevant really.

Very true! Especially when Mine's and Amuse has already began selling reflashed ECU with 585wps (just with a less restrictive cat as well as an exhaust system.
Now that is if the N.A. version will get the same ECU setup thou. Cause US-specs 350Z uses different ECU than the JDM-version which is not interchangeable.

"Speculations" show ; just like tere said "480 at the wheels.....crank 520" and also, since were on the topic of rumors or truth. I heard that the 2010 V-Spec GTR is only gonna be released in Japan and neither in the US or Canada. Im not too sure about Australia though, so anyone got any answers holla at me.:cool:

That's interesting. For some reason I don't believe that but it is always a possibility. I know some people who were considering the GT-R opted to wait for the V-Spec but that's too long of a wait for me. :eek:

[Ev0H8t3r]

Im waiting...I guess we have to wait hehe...seriously, I never wanted something so much in my life...well beside my wife, and hitting the Loto!
wow, Im 2 for 3! Maybe I'll hit the Loto this summer while on vacation! LMAO!
Heck if I did I would open up a GTR store/shop, GTR 24/7!

sorry got off subject...;)

[GT-RFan35]

motortrend put the car on the dyno and it read a little bit over 500 hp and I also read somewhere that it has 430 hp to the wheels...
