rice boys have moved in,ditched the tyres too.


580bhp from an exhaust :lol:

Can you read Japanese? Can't tell what the first dyno was saying... It claims 580 hp up from 480 hp... with ECU blah-blah-blah... thought the ECU was uncrackable? Or did Amuse build their own ECU from the ground up?

But from what I can tell, the second dyno details a 25 ps gain from the exhaust or the ECU work.. can't tell which. Note that the tcf (torque correction factor) is set at 1.10 (in other words... wheel power times 1.1 to derive brake power)... making the 481 ps reading simulated "b-ps" not measured w-ps. Which pegs the "before" reading at about 437 w-ps... or nearly 40 w-ps more than with "wheels on" dynos. Which correlates with edmunds' results perfectly (which showed the GT-R is nearly exactly as powerful as the 911 Turbo on the dyno)

To get the 580 ps result (527 w-ps on the dynapack, corresponding to just under 500 on the Mustang or Dynojet), Amuse has most likely reworked the ECU (looked it up... confirmed... Amuse and a few others have already hacked the "untuneable" GT-R)... word is, the 473 bhp engine is electronically limited. If it's possible to get 580 bhp out of it from some simple hacking (from the video, it seems they've fiddled with the boost) and an exhaust, then the GT-R is an even bigger bargain than previously thought.
 
GT-R Spec V Spy Shots

The photos are big so just go to the gallery

The Nissan GT-R has already proven it can more than hold its own against competition like the Porsche 911 Turbo and Chevy Corvette Z06, but don't forget that Nissan still plans on revealing a victory specification, i.e. V-Spec, model of the car. Spy photogs from KGP Photography recently caught what they believe is the GT-R V-Spec being unloaded from a transport truck at the Nurburgring in Germany for testing. While the car doesn't outwardly appear as different from the base GT-R as we expected, some differences are noticeable including more air intakes in the revised front splitter, new wheels and a different brake package (carbon ceramic perhaps?), and what could be a carbon fiber rear spoiler. Reports suggest that whole body panels on the Spec-V model will be comprised of carbon fiber, which should, among other things, help reduce the car's portly weight by at least a few hundred pounds. While the spy shooters didn't get to hear the engine fire up, rumor has it that the GT-R V-Spec will be more powerful than the base model, an achievement that shouldn't be hard to accomplish considering dyno results suggest that the twin-turbo 3.8L V6 is already making more than Nissan's official claim of 473 horsepower. We're also not sure on what Nissan's export plans are for the GT-R V-Spec, though it will be sold in limited quantities to some lucky Japanese for sure.

I thought we were getting the V-Spec and it was the GT-R "Evo" that was going to stay in Japan?

Add enough power, my guess is that it'd do a damn good job trying to run-down the ZR1...
 
RE: Autoblog... make the dyno-abuse stop... please... just read Motortrend's dyno... they dropped a gear because they thought the long pull in the higher gear was causing heat soak... BULL! I've seen six-speed cars miraculously gain 10% more hp in 3rd gear over 4th because 3rd was so short... I don't doubt the torque multiplication is at factor here, once again, even worse, due to the GT-R's seven speeds.

Will someone please just pull the engine out of the car and dyno it on an engine dyno, so we'll know once and for all?

oh yeah reliable source that :lol:

For once... yeah... I agree with you. Let's wait for the official or semi-official word.
 
GT-R has 6 speed 'box.. oh well, 7 if you count reverse.. ;) and i'm going to wait official figures from Nissan. Though, I wouldn't be surprised if the car would actually BE that fast or even faster.
 
It will likely depend on how much weight is cut (if any) and of course how much extra power is shoved under the hood. I think Car and Driver was expecting the car to be making well over 500 BHP at the crank, given their test numbers (with launch control), so anything extra will likely depend on the grip of the tires and the overall strength of the system.

...Because even when those engineers are baffled at how it gets going so fast, everyone starts to wonder how everything is working...

My bad... I should have specified. 7 gears... 1-6, plus D. :lol: Sorry... got it mixed up with the V-Spec rumors.
 
Apparently, motoring magazines and sites are frothing mad about this car... you could find out that the door jambs are unintentionally magnetic and it'd be news.

But given that these times are hand-timed by bystanders... hmmm... +/- one or two seconds?

Or does Nissan have two cars with the same number plate?... you know... drive one by a section of track... then exactly seven and a half minutes later... drive the other past the same section of track? There's so much hysteria about the car already, I wouldn't put it past them to pull this prank... :lol:

I guess the big question isn't how much power... apparently, 600 bhp isn't that far off with minimal tweaking... the question is how much weight they've removed... something that we may not know till close to press-time.
 
Quicker than an Zonda F Clubsport?! Looking at that video of it against a GT3 shows how much of an acceleration advantage it has out of corners even against a rear engined car so I guess it wouldn't be that much of a surprise. But still....
 
I'll believe it when I see it, as always. I noticed they put the ZR1 times on there as well, which just like the GT-R, are completely unconfirmed and should be flagged immediately as something preliminary and in no way representative of what the road car may be able to do.

If the times have increased that much, hundreds of pounds must have been shed in order to make the GT-R that much faster. Or, if Nissan has the guts, they increased the power big-time.
 
Basically you could think of it like Mercedes, where they have the AMG 55 series, and the more powerful and more expensive AMG 63 series. In Chevy's case, you have the Z06, and the more powerful and more expensive Z51.

Yup. Let's wait for the official.

And, yeah... most likely... a lot of weight and a lot of power. Hmmm... at that time level... I'd say the under-rated accusation, should Nissan choose to say that the V-Spec is "merely" 500 or 550... would be warranted... completely.
 
I think I found Nissan's secret powerplant for the GT-R V-Spec...

The Nissan GT-R can now lay claim to being one of the fastest production cars in the world after GT-R chief test driver Tochio Suzuki completed the famous Nurburgring circuit in Germany in just 7 minutes 29 seconds. According to our records, this puts the GT-R in second place for fastest laps by unmodified production cars just behind the Pagani Zonda F which posted a time of 7 minutes and 27 seconds last November. The time completely destroys the GT-R's previous best lap of 7 minutes 38 seconds achieved last year in slightly damp conditions.

Kazutoshi Mizuno, Chief Vehicle Engineer for GT-R said “At last year’s testing, we were frustrated by the conditions at the Nürburgring, always believing that the GT-R could go under seven minutes 30 seconds, the GT-R proves it is among the fastest mass-production cars in the world. We set out to build a multi-performance supercar accessible to anyone, anytime and anywhere – I believe the GT-R has delivered that promise.”

The world can now look forward to a response from the GT-R's main competitor, the Porsche 911 Turbo whose best time stands at a lowly 7 minutes and 40 seconds.

No, that's not Nissan's...However, I think I'll ask you where the hell you got that. Doc's been looking for it for some time now.

Out-of-character: the new time MUST be a V-spec. it knocked 11 seconds off the previous time.
