Car and Driver Dynos 5 Nissan GTRs.....Old School Sandbaggin again?

[EJ25RUN]

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.

Car&Driver....

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 vehicles.

So it's quicker than previously thought, big deal.

tu no comprendes?
Nissan turned the boost up on Car and Driver's test vehicles before giving them to Car and Driver, yielding better test results than your average GTR... in other words you go buy a GTR, and it will be slower than Car and Driver would've told you.

You could always turn up the boost...

no, thats not what it means. It means they were underrated from the factory. Nissan is notorious for this. It makes well over 40whp more than it should/advertised. there are video's on youtube of bone stock GTR's running 11.7's with Novice drivers and on street tires (stock). No way thats 480hp. This is also not a bad thing

none of the gtr's will ever dyno the same. because they are handbuilt.. some will make more.. some will make less.. that was the word on the number

thats what she said.

but yea thats what i've heard aswell, and according to top gear, you can't use a transmission from 1 GTR and put it into a another GTR because each or custom tuned to each engine....some how

Who knows, the GT-R is a car I'd keeps stock anyway. I'm not the type of person that wants 1000whp or the fastest car on the street. I would be more than happy with 400 whp! It's not the fastest car on the street but then again what is? The veyron....which of I've never seen any roaming the streets. And most people who mod cars have less than 300whp, so the GT-R would spank 95% of anything on the road. Honestly my max isn't fast and I've spanked almsot everything I've raced. I'v only lost to a viper and a boosted civic...damn those lightweight eg-6's...

That is only true for American cars.

And you need to see the video of what they build the GTR's motor inside off. It's a vacuum sealed box.

i was being facetious brew

[Alan®]

GTR=GOD LOL

[Atlblkz06]

ALL AWD cars lose exactly 20% in driveline efficiency, therefore this car is under-rated?

Right...

[RL...]

They are nice!!!!3.3 is fast as hell for a stock car costing 72k

[ttman]

wow, now it just needs to go on a weight loss program.

[Kevykev]

That last dyno pic is Bangin'

[matthewAPM]

sandbaggin?? maybe

but just wait until a ZR1 is put on the dyno....

[Leadfoot_mf]

so can you dyno your car part of a ppi lol to make sure u get the most for your money?

[Catnip]

I was told turning the boost up on a new GTR would make it flip a shiit.

[OnURleft]

Yep.. A car of that weight, with that gearing should have around 520-540hp to run 11's.

Is that alot of power? My 240 makes that sad times
