Is Nissan lying about GT-R horsepower? Pretty much.

Back in the late sixties, automakers sometimes purposely under-reported the true horsepower that their solid-lifter, over-cammed and over-carburetor'd monster V8 engines actually delivered. More recently, some manufacturers have overestimated the real power of their vehicles, which has led some to distrust factory horsepower numbers. Owners of the uber-impressive Nissan GT-R have been wondering if they've been lied to regarding real horsepower figures too. But in this case they may...<br/>

580 at the crank..........................


boooooooring!

hahahahahahhha

[vvtisupra]

according to a young scholar. Measuring hp at the crank is like measuring your penis sized from behind your balls

[Jordn]

Thats not how its done?

:hahano:

Damn.

[Antihero983]

old news. Motor Trend dyno'd it ages ago.

ahh, i gotta go google the motor trend one again to see what they had come up with..

[norbac]

maybe they meant hp at the wheels, and somehow it went out as crank hp, but i like the fact that it has more power than what one would think

[axiomatik]

I read that Nissan had responded to Motor Trend's assertion about horsepower. Motor Trend based their figure on an assumption of like 18% driveline losses. Nissan said that the engine does indeed put out 480hp, but that the high figures for power at the wheels was due to a very low friction driveline, with losses more like 10% (I don't remember the actual number).

[CA-mazing]

all i know when they first released it to public view in New York (< i think) and Nashville, TN (< i know, i was there), they had like 3 Nissan engineer experts here in Nashville that knew the GT-R inside and out. I remember listening to them talk about the tuning that was involved and how the twin turbos were tuned to engine and everything. And they said more hp could be gained through further tuning. and yes i know what you're going to say...cars like this are already tuned to full potentional and the post is talking about underestimating actual HP. i know this, but i clearly remember them talking about it cuz i asked them if more HP could be produced with out modification. they said yes, but only mere HP and TQ gains of like 10-20. but anyway, i still love the door handles, haha!! ooo, and my dad works at nissan, thats how we got into to see the GT-R, and he's heard that the only complaint that GT-R owners have is that when they "drive" the car, they can't hear the roar of the engine or exhaust.....hahaha!!!! i'm dead serious, they feel sad that they paid all this money, and can't hear the roar of the exhuast at 7K RPMs, hahahaha. thats just hilarious!!

580hp.
4000lbs.
$70,000

I'd much rather have a car with 290hp that weighed 2000lbs and cost $35,000.
Less is more.

And to beat a dead horse, one with a real manual transmission that uses a clutch too.

My main 2 gripes about the GTR are shared with you. 4,000 lbs is waaaaaaaaayyyyyyyyyyy too much weight and why the hell won't nissan put a regular manual transmission in it? BASTARDS!

Ya, 3815lbs is pretty damn heavy coming from someone who's a weight junkie (my mkiv supra is 29xx lbs now). Also, the paddle shift can be pretty costly to replace. I'll agree that the weight is too damn much and a 6speed option would be nice....so I only hope my 2009 black/black GT-R on order lives up to it's expectations :)

I do know it should turn some rather fast, rather consistent laptimes (which is why I bought the car) based on everything we see so far, and also the dual-clutch 6speed paddle will help with this too. There's nothing like mastering heel-toe technique and good shifting work but this is definately going to be a FUN track car. I already have about 250lbs to take off the car rather easily without removing the interior (besides bucket seats which I'll want anyway for the track). Can't f'n wait, we'll just have to see how she stacks up against my moton-equipped S13 and 2980lb 660rwhp mkiv Supra ;)

It does have a clutch, hell it even has a twin plate in there. Its just that there no clutch pedal. A computer does all the shifting for you instead of a clutch pedal.

I think its because you can't shift as fast as a dsg and you will never able to heel and toe and rev match as well as the dsg box.........besides only 9% of cars sold today come with a manual transmission......
