Lies, damn lies and HP ratings: C&D dynos five Nissan GT-Rs 
Originally Posted by Damon Lavrinc @ AutoBlog
From the beginning, the Nissan GT-R's performance figures seemed too good to be true. Weighing in at over 3,800 pounds and packing a claimed 480 hp, the 3.5-second sprint to 60 and 11.8-second quarter-mile time just didn't add up. And then the tests began...
Buff books and online outlets began publishing 0-60 runs between 3.2 and 3.4 seconds, and quarter-mile times began dropping quicker than a co-ed's IQ on a nitrous binge. CARandDRIVER.com discovered a similar discrepancy between five different GT-Rs and finally decided to get some time on the dyno to get some real-world numbers.
CARandDRIVER's first tester ran to 60 in 3.3 seconds and past the traps in 11.5 seconds at 124 mph, causing C&D's scribes to suspect that Nissan engineers cranked up the boost on the evaluation vehicle. Shortly thereafter, two more GT-Rs arrived at their offices, both recording significantly slower quarter mile times and confirming their suspicions. Unfortunately, time constraints prevented either vehicle from getting up on the rollers. That would have to wait until Tony Swan returned with his GT-R after campaigning in the One Lap of America.
Surprisingly, Swan's GT-R performed exactly the same in performance tests as the first GT-R C&D tested. When they finally strapped it to MotorCity Speed's Mustang dyno, No. 4 put down 415 horsepower to the wheels, and with an estimated drivetrain loss of 20 percent (an average on most all-wheel-drive cars), that meant output was closer to 519 hp, rather than Nissan's claimed 480 hp.
Not content to leave well-enough alone, CARandDRIVER procured a fifth GT-R, which returned almost identical 0-60 and quarter-mile times as the fourth vehicle, along with 420 hp at the wheels on the same dyno.
You can read all the details at CARandDRIVER.com, hear Nissan's explanation for the discrepancy and see charts of both the dyno pulls and the boost levels on two of the five vehi

i am so fed up with nissan and all their bull, this is just insane.
1. racing and using launch controll voids the waranty
2. releasing cars to testers with upped boost and making 50 more rwhp then the ones they release to public, without letting anyone know.
3. having a decked out gtr at the ring with better tires and other unknown mods so they have a very low time.
I cant wait to see what else they have been doing.

Nah, its a little on the ugly side. I feel the older skyline it replaces looks better. I don't like the interior that much either, it looks like it was designed in the 90's or something all kind of blocky and squared. I think I would get tired of its looks.

wait...according to the article the cars are under rated from the factory...similarly to how our LS1 cars were. so whats the problem.
customer cars are turning BETTER numbers than the nissan test cars.
