Indeed it does. However, it doesn't prove if Nissan used a car with stock boost levels, suspension, or brakes.
Either way, I doubt it's worth it for Nissan to "buy" one from a dealer and run it again for Porsche. They're probably more interested in running their upcoming higher spec model(s).
That video doesn't prove anything at all. Car could easily have been tampered with. Who says it doesn't have an extra 100 (or more) horse power? That would just be increasing the boost a little bit. Brakes could be better, suspension could have been modified, the chassis could actually have been made of carbon fiber throughout throwing off a few hundred kilos. The tires may have thread patterns in them, but the rubber can still be soft as a race car providing way better grip.
I say someone buys a Turbo and buys a Nissan and runs them on the ring at the same day and looks at the outcome. Nissan can't cheat physics.

Guys - this is almost three months old!!! If you follow cars closely, this is very old news. I do have to agree that the GT-R time is highly suspect.
If there are any updates, I'd like to hear about them.
There are some new facts around the 7:29 time....
First the car was driven by an ex-F1 driver. Suzuki. So assuming F1 drivers are faster than journalist, this would account for some of the variance.
Second, Nissan has admited it used a preproduction ECU program. Being a turbo car, the opportunity for Nissan to cheat here by delivering power is easy. It would never be tracable. A couple of my friends in another forum did a regression analysis of power vs. lap times and the sweet spot is 550-580 hp....well above the 500 of a stock GTR and well within the limits of a preproduction ECU program.
Nissan gets an "A" for viral marketing but an "F" for product support. There are many people who have had their transmissions grenade without warranty coverage.
If you take DSC off and use launch control, say good bye to your warranty.
In MY 2010, Nissan is going to remove launch control and increase the price..... So set the expectations for performance and price and then change everything. Scummy.

recently spending a good month and a half driving the gtr as my daily driver i can tell you that the transmission is strong and the warranty issues are coming from abuse. any car company that can prove that you have launched the car over and over will deny you warranty. in europe my m6 launches at 4500 rpm here in the states its 1500 rpms why because of warranty. i love my m6 and currently fought tooth and nail over guess what tranny warranty issues...back to the car the gtr is truly a technical marvel. its just so well put together as a race car...but here is my issues with the car of the year. interior is not as nice, the ride is very stiff i think our m6/m5 racing mode is this cars comfort mode. needs HUD seats not as good as the m6 as far as adjusting for lumbar support. No parking distance sensor. enough with the bad the car is super fast and brakes like nothing i have ever driven. i love the fact that this car is out and so should everyone who loves cars. this is the kick in the mouth that the M division and all super cars need to give us whatever crazy bar they want to exist. I love my m6 and its just the perfect balance of power and comfort but the gtr is the weekend car that will have people staring walking up to you and drooling,
Unless you average out a bunch of laptimes of a given car, either one "freakishly" fast lap or a "misgearedfully" slow lap is not a representation of how fast that car is...
In addition, how familiar a given driver to the track and the car can make a HUGE difference to the laptime. And the driver's mental/physical ability on that given day, not to mention his skill level?
Also, dual clutch can always shave off a few tenths during EACH and EVERY gear shift. Did we count how many gear-shifts were done in that 7:29 run? Porsches are notoriously hard to shift fast (the antithesis of a Honda Civic) due to their longish travel clutch pedal and the stick. Even if the Porsches CAN run faster around the Ring, the little "tenths" they give away CAN add up to a slower time. It's not physics here, just the reality of progress.
There are other factors to consider, i.e., was the GTR that Porsche took to the Ring "broken-in"? (we all know a few thousand miles of driving actually improves performance to a car); what about the "fressness" of the tires? (a slightly used/shaved tire can outstick a brand new one); was the IDENTICAL fuel used? (esp. for a turbo, a few octane off can mean big hp diff), etc....
Unless most if not all the factors/conditions can be set constant, comparing any ONE single laptime of a car to ONE single laptime of another should be taken very lightly.

You seem to have some kind of agenda against the GT-R. Why? I don't know; perhaps you should actually take a ride in one. I will attempt to once again straighten out your 'misconceptions'
One: there are NOT many GT-Rs whose transmissions have failed that are not being repaired/replaced under warranty. There have been about 3-4 cars whose transmissions have failed due to abuse. The cars were not at normal operating temperature; LC was used multiple times in row; the cars had low miles and had not even been broken in correctly. Name me a manufacturer who would warranty vehicles that had clearly been abused; there are none who would do so.
Two: turning VDC off does not AUTOMATICALLY void the warranty on the car. Nissan clearly states that they can refuse to warranty a part that fails during the time VDC is turned off, but it is reviewed on a case by case basis.
As for the 'ring times: the GT-R may well have had the ECU 'goosed' slightly; God knows it's easy enough to do, but who's to know? As for the fact that it was driven by an ex-F1 driver: Porsche routinely allows Walter Rhorl, (sp?), to derive the 'ring times for its cars, and besides being one of the World's best drivers, he probably has more laps on the 'ring than anyone. Hence I doubt that any advantage was realised there.
Lastly re: the speed of the GT-R. Anecdotely, new owners of the GT-R who have taken it out on track in stock form, and who have owned other very high performance vehicles, have stated that the GT-R is substantially faster; hence for me, I can believe that the GT-R could post such a quick time at the 'ring.
Remember: both Nissan AND Porsche have an agenda here.
Great post and than kyou for your valuable feedback!
So you have an M6 in Europe as well?

No agenda against the GTR, I had a short ride in. Launches out of corners great. In fact, I love the car. What I don't love is Nissan corporate.
Warranty issue, you can nuance it but there has not been one warranty denial on launch control for SMG AFAIK but lots on GTR.
The Nissan viral marketing and bait-n-switch tactic is unacceptable.
