performance changes via MotortrendI like how Nissan says it now does a 7:20 around the ring in street trim. Yeah fucking right. + A fuckton of weight and only + 45 BHP = -6 seconds on a laptime? Yeah right. They still haven't owned up to that ass-pull 7:26 or whatever time they had before.
The VR38DETT engine power climbs to roughly 520 horsepower. Torque increases to roughly 450 pound-feet and is delivered over a slightly wider 3200-6000 rpm band (previously 5200 rpm). The improvements are gained via changes to turbo boost pressure, valve timing, and air mixture ratio, reducing intake air resistance by enlarging the inlet pipe diameter and reducing exhaust air resistance through use of an enlarged section of exhaust pipe. The GT-R also manages to drop fuel consumption slightly, and CO2 emissions fall, too.
Acceleration should improve, aided by what Mizuno called "launch control" embedded in the VDC stability control system's 'R' mode and the six-speed dual clutch transaxle. However, perhaps aware of previous controversies regarding GT-R launch control, the official release refers only to improved "starting performance." At the opposite end of the spectrum, the transmission also now has an economy mode, while a new ultra-low precious metal catalyst aids emissions.
The GT-R's exceptional handling should benefit from a stronger body, including a carbon composite strut brace. A front suspension geometry change seeks better turning grip and straight-line stability, while a rear roll center adjustment is designed to improve tire grip and feedback. The GT-R also swaps to a lower friction shock absorber and a thinner front brake rotor that is 10 mm larger (390 mm) than its predecessor. There's no mention of mods to improve the adjustable suspension's ride quality. Lighter and more rigid 20-inch RAYS alloy wheels and new construction Dunlop run-flat tires complete the chassis update.
Externally, the 2012 GT-R appears little changed from its predecessors, but enough has been done to drop the coefficient drag from 0.27 to 0.26, while downforce is increased by roughly 10 percent. Enlarged bumper and grille openings are giveaways, as are the double fins and LED running lights mounted in the front corners. At the rear are a lowered and extended bumper and enlarged tailpipe finishers.
I'd go for the GT-R. It's a more impressive car to me than the ZR1. The ZR1 is a better car than the Z06, yes, but the improvements are not astonishing. Better oiling for the motor, supercharger, better gearset, CF body panels, magnetic suspension, etc. Okay great, so basically it's an improved version of the Z06. The ring time is definitely impressive, but another 600hp/3400lbs car also achieved virtually same performance....the new Viper ACR, which uses basically same formula....manually rowed, high HP, RWD, etc. I honestly think with the proper mods a C6 Z06 can easily come within reach of ZR1/ACR performance since these can be thought of as the 'same' cars. The GT-R though is something unique and new from Nissan. It's not the best looking (neither is the ZR1 imo, especially with that utterly tacky/ricey looking window on the hood) but if you brows on GT-R forums alot of the public think its some kind of hot exotic (including chicks, hehe). Not to mention it's cheaper, and has 2 extra seats for those groceries and kids. I'd get the new Viper ACR over the ZR1, anyway.I'd still rather have a ZR1. I know, I know...(giant) flamewars, etc. ensue after a statement like that but it is just too damn ugly. If I buy a car for that much money, it had better impress me in every way...and maybe get the girlfriend a little...uhhh... The newfound power is nice though. I just wish Datsun wasn't so shady about their times.

At this time, those who still think Nissan is in a conspiracy to try to deceive the world about their 'Ring numbers will not be convinced otherwise. And as you said, all the other "official" ring numbers come from manufacturer claims and there's no way to confirm what kind of car they used. Even in-car videos don't show what chassis/engine/tire/etc. mods, if any, were done. Of course we know from 'common sense' that a car with a xyz amount of HP with abc amount of weight shouldn't run so many minutes and so many seconds.
If you think that video is bullshit, then you'd have to same the same about any other manufacturers' claim, whether they've provided a video or not. Why are Nissan's claims always viewed as less credible? It pulls similar laptimes in comparison to other cars on the ring as it does on other tracks.
I don't see why an almost 10% increase in power along with a complete chassis overhaul wouldn't result in a 6s laptime drop.
Here we go again everyone! Yipee!I like how Nissan says it now does a 7:20 around the ring in street trim. Yeah fucking right. + A fuckton of weight and only + 45 BHP = -6 seconds on a laptime? Yeah right. They still haven't owned up to that ass-pull 7:26 or whatever time they had before.
Well, at least he lives up to his screen name, lol.2008 called and wants it's stupid internet arguments back...
