it would be interesting if Nissan got this engine SAE certified...

 

AWD cars are known for having lower trap speeds than similar RWD cars, are they not? The GT-R's 116 MPH trap speed doesn't surprise me at all.

 

Unless I misread the Edmunds test, they used a Mustang dyno.

I believe I've heard that the 2007 911 Turbo (which trapped 122 when Car and Driver tested it) is underrated as well.

 

The GT-R wouldn't have been able to do that test.

 

Usually cars that hook up better at launch trap lower than ones that spin the tires a bit.
Ex. someone on street tires can run 13.2 with a 2.2 60ft and 110 mph trap. Or they can put on DR's and run 12.8 with a 1.8 60 ft but only 108mph trap speed.

Trap speed is also an indication of overall hp and obviously one with more power would trap higher speeds even after it's adjusted for wheel spin.

Just from the numbers given in this test the GTR hooks hard and moves out quicker than the Z06. The Z06 has more power and a better power/weight ratio and so once traction is reached and the car will accelerate faster than the GTR.

So for the bench racers the GTR would probably win the stoplight battle and the Z06 would own the upper mph roll races. But on the street with different tires and road conditions all bets are off.

 

They did 2 dyno tests in the Edmunds article... one on a Mustang dyno and one on a dynapack.

I'd be pretty surprised if both the Porsche and the GTR are underrated... by pretty much the same amount at that.

 

Why? The entire point of the GTR's existence is to show that Nissan can beat Porsche at their own game. The 911 Turbo has been the Skyline's performance target for decades. So why shouldn't it be similarly underrated?

 

Sounds like an automotive conspiracy theory if I ever heard one. "Porsche underrates their cars, so we will to..."

Who knows, you may be right... I could honestly care less. Like I said a few posts back, the car is what it is, and it performs well. If it actually gives you 550hp, great, its even more bang for the buck than advertised. If its putting out whats advertised, great, the car is putting down its power very effectively.

 

Could not agree more! Well said. Wonder if GM will make the z06 with the ls8 in response?

 

It's not a conspiracy theory on my part (although I agree that it sounds like one). I'm just saying that Nissan targeted the 911 Turbo for everything with the GTR, so why not this too?



This is impossible. The GTR's drivetrain would have to be adding horsepower.

I really doubt that. GM already has a supercharged Corvette with the ZR1.

 

I wouldn't discount it just yet. The LS7 is expensive to build.

 

Props to the car. I'd like to see if anyone can run a 10.8 @ 129 with a stock one though.

 

I doubt you'll ever see someone run faster than 11.5@117 with a stock one. Slicks will hardly make a difference, due to AWD, and the computer nanny pretty much negates any skill involved. Remember there's no clutch, and no speed shifting. Just hit the gas and tap the shifter forward.

 

And why does everything have to be AWD?

 

It doesn't, nor, IMO, should it be. The Corvette is a uniquely American sports car, seems to me it has done pretty damn good sticking to it's V-8, rear drive roots.
