heavychevy - i do not believe everything that everybody at nissan says... i have my own issues with nissan. but none of them are being represented here. so i will keep those to myself.
and is it true that japan does not allow 'launch control'? if that's the case, then we should appreciate the legal position he has by not stating it anywhere, and never calling it that officially.
that's like stating that the skyline gt-r only had 280hp. isn't that another lie? and the r34 skyline gt-r v-spec also had 280hp. another lie. where's the outrage?
*edit: i thought it was clear that the japanese government has their own official and unnofficial regulations.

Poster Kris on the GT-R site ran his GT-R and with traffic, and being a novice driver ran:
Lap Time: 7:57
Mods: Cobb AP, Carbotech X12 pads, Willall Y-pipe. Traffic con: I overtook ca 2 or 3 cars in this run, didnīt slow me too much.
That is a very impressive time for a novice driver, and makes the previously posted Porsche driven GT-R times suspect to say the least.
Not even close to a stock production car, the driver might not be the same class as HvS or WR but anyone who drives any car around the ring at that speeds isnt a bum.
Again Nissan can have a sub 6 minute lap and claim it as stock, if everyone can only get a 7:40-7:50 lap then the GTR is really only a 7:40-7:50 car. As for passing 2-3 cars it reall depends where he passed them his lap shouldnt be slowed down enough.
Someone private owner should really test the GTR against the Enzo and the Zonda and see if it can really keep up. Afterall shouldnt the GTR be an easier car to drive?

Really, it's all just hot air and rhetoric until independents put it through a "consumer reports" test, and by that I mean take one of each off the showroom floor and run them several times around and take averages. Othetwise, there are too many unknown variables.
This is how I see it: Nissan claims a stock GTR ran a 7:27 at the 'ring, Porsche says the car that ran the 7:27 is not stock. Either Porsche and it's engineers understand little of automotive engineering, or Nissan is lying. My money is on Porsche.
The lines taken by both drivers seems to be pretty good yet this particular independently ran GTR could hardly get away from a 1993 Viper with roughly the same power. The ACR, ZR1, Enzo and Zonda should all easily beat this 421rwhp Viper especially on a straight line, yet they cant with the GTR around the ring.

But your exact words can be flipped to say "Either Nissan's engineers understand more about automotive engineering, or Porsche is lying. My money is on Nissan."
Personally I think the real time is between Nissan's claim and Porsche. So maybe around 7:40?
no. there is no launch control button. there never was. it was just a series of button pushes.
but now there is an acceleration feature that is always on. no need for button pushing. just brake, gas, release brake.
Now you're going to preach the same lies that Nissan is selling? As if you actually believe that? A series of buttons that enables you do a 4500 rpm clutch dump is called LAUNCH CONTROL!!!!!!
I honestly can't believe you will buy absolutely anything Nissan is selling. I have a bridge to sell you that goes with those pack of lies you bought. I'll give you a good package deal.
__________________ The GT-R is harder to drift than a 997 TT or 997 GT3, therefore if you are trying to drift, the GT-R will consequently get a faster lap. Normal apexing and driving not included.
We have some upcoming track events with a GTR or two.
It should be interesting to say the least.
Last year I carelessly passed a GTR on a drive that I was on.(he was my "backmarker")
My car (like the one Nissan is blazing around the Ring) is "stock" as far as I know.
Ok, letīs say itīs a typo and drop the STi out of the discussion. Iīm still waiting for your explanation why the GT-R canīt make the time Nissan has made. Period.
It's not that difficult... power to weight ratio is worse than the 997 turbo (and topspeed the same). due to the gearbox it makes up for this in acceleration, but the higher weight is still a problem, more on that later on.
In a straight line, the 997 turbo and the GT-R are about the same, with the 997 turbo being a tad quicker... (according to tests).
In decelleration the weight will be a problem. Now I know that the Nissan has great tires, but still, it won't be able to get the 997 turbo in this area.
So it's up to cornering then. The 997 turbo has great cornering abilities for a road car. So even with the great tires, the great balance, the great 4wd, it simply cannot win almost 30 seconds in this area, since it is also a road car. Impossible.

And while youīre at it, please explain how the Carrera S with sport tyres can outrun the more powerful 997TT on the Ring? Both driven by HvS and you can see both times on the link I gave you and that you also quoted.
No problem.
Power to weight is 3,71 kg/hp for the C2S and 3,30 for the turbo. 12,4% advantage.
However, the C2S has 7 gears and PDK. It doesn't need the 7th gear on the ring, and i am going to delete it for comparison. Why? Because power to weight has to be corrected with gearing.
Assuming that the C2S will go about 270 km/u in 6th we correct 270 against 310 and the C2S now has a power to weight corrected with gearing advantage of 2,1%. I repeat, advantage.
Having 2wd is no disadvantage in the dry, lighter weight is an advantage. So it is logical that the C2S is the quicker one.
If the turbo gets the 7 speed PDK, it will be faster than the C2S

No, YOU have no proof that itīs false.
I think the fact that all independent test show that the Nissan is a 7:50 car is proof.
Perhaps the Nissan driver is out of this world fast with a car, but if you would like to assume that, you would have to assume that he will go around the Ring in a 997 Turbo in around 7:30. I don't, you might.

But please try to explain it, Iīm sure itīll be entertaining.
