My buddy's bro just got a 07 911 turbo. I've never felt power like that thing in my life. It was scary fast.. it's basically a street legal race car. Very comfy too surprisingly!

That is because the GT-R isn't faster than the 911 Turbo.
Car & Driver tested the M3 vs. 911 Tubo vs. GT-R
The cars were tested in the same conditions, same track, same driver, same day. The 911 turbo had the fastest 0-30, 0-60, 0-140 and the fastest 1/4 mile. It also had the best 70-0 braking and skidpad numbers. Also surprising the 911 turbo had the best gas mileage.
And the best thing is the 911 just got refreshed, and the turbo is next.![Big Grin](https://5series.net/forums/images/smilies/imported/biggrin.gif)

I don't know about that, the head of Nissan NA said that they have gone through great pains to make increasing the HP of GT-R VERY difficult, he repeated the same thing to Jay Leno when he tested the car. http://www.jaylenosgarage.com/video/video_...html?vid=244892

One of the GTR engineers explained the reason it makes so much power is because there are very low friction bearings used in the car.

There is also some speculation that this particular GT-R is down on power compared to other GT-Rs as it has been thrashed by testers.

That is what this thread is about, the GT-R isn't exactly down on power. The numbers very conservative.
I know LC can work some magic, but when a car weighs considerably more and has less power, but has almost identical straight line speed. Something is a little strange.
No matter, the turbo has been out for a few years, you can bet Porsche has something up their sleeves. They just refreshed the base 911's, the turbo is next.
What are you saying, the car doesn't last too long? That isn't good.![Frown](https://5series.net/forums/images/smilies/imported/sad.gif)

In this test, http://www.caranddriver.com/reviews/compar...n_test/(page)/1 , the GT-R put up a paltry 111mph trap speed. That trap speed does not indicate underrated horsepower ratings in the least.
Where do these discrepancies come from? If the GT-R really had ~580bhp then it would have a trap speed in the mid to high 120mph range. Who am I to say that the car won't last long as it's all speculation at this point. Perhaps some of the early cars really were ringers or maybe this particular GT-R is a poor example for whatever reason.
Regardless of what the actual HP ratings are, the GT-R is showing that it can produce very competitive lap times even when down on power (as indicated by acceleration times), and with it's hefty weight penalty compared to it's competition.
Here are some results from that C&D comparo. From these results, the GT-R would be miles behind in the straights, but somewhat competitive lap times indicate that it's transmission, AWD and suspension really are that good.
Corvette Z06
Curb weight 3180 lb
0-60 mph 3.8 sec
0-100 mph 8.3 sec
1/4 mile 11.9 @ 124mph
70-0 mph 159 ft
Slalom 62.9 mph
Lap time 2:01.7 / 79.9 MPH (Button Willow No13 2.7 mile)
Viper SRT10 ACR
Curb weight 3420 lb
0-60 mph 3.4 sec
0-100 mph 7.7 sec
1/4 mile 11.8 @ 126mph
70-0 mph 149 ft
Slalom 71.9 mph
Lap time 1:55.7 / 84.0 MPH (Button Willow No13 2.7 mile)
Porsche GT2
Curb weight 3300 lb
0-60 mph 3.7 sec
0-100 mph 8.1 sec
1/4 mile 11.8 @ 121mph
70-0 mph 155 ft
Slalom 67.2 mph
Lap time 1:59.7 / 81.2 MPH
Nissan GTR
Curb weight 3920 lb
0-60 mph 4.1 sec
0-100 mph 10.2 sec
1/4 mile 12.6 @ 111mph
70-0 mph 155 ft
Slalom 67.6 mph
Lap time 2:01.1 / 80.3 MPH (Button Willow No13 2.7 mile)
Oh and if the GT-R raises the bar higher and pushes the 911 to higher levels, great, but realistically, I don't think Porsche could care less. The GT-R is a wonderful performance bargain, but there's more to speed when considering cars. If the GTR could be had near MSRP, I'd rather have an e92 M3 or a used 997S for the price. If the price is more close to 100K with markup, then I'd look at a used GT3 or turbo. Really entirely different markets and cars IMO.

Edmunds Inside-line tested the GT-R, theres a video on youtube you guys can look up.
Nissan tests
0-60: 3.5 sec
Inside-line tests
0-60: 3.2 sec ( testers say they could've shaved 1 or 2 mils more if conditions were better)
Most say that the GT-R is overrated, I saw it was the only car that was created into a hype-beast, lived up and exceeded those expectations. After all who can complain about a nissan handing ferraris and porsches their lunches?
