Corvette1221

Guys,

Before you go hating me for posting this, let me just say that I have a Z06 2006 Corvette and love the car. I just noticed that many people have been saying how the lap time on the Nissan GTR is bogus. So I found this, thought you might find it interesting.

Why am I posting this, because I am a car enthusiast and I love all cars. Though I don't think I would ever buy the GTR I am surprised by its performance.

Knowing many others that bought the Corvette Z06 like myself appreciate performance as well, so I thought you might find this interesting.

It has a lot of detail, perhaps other members of this forum can decrypt it.

very impartial crowd there

We will call it even as I think the same about the GTR and all the junk from his country Korea where they allow just about zero imported vehicles.

the nissan eng was quoted saying they used cut slicks for the test also.

blitzu

That's great and all but it still doesn't explain how a 3800 pound 480 HP car out handles, is faster, and supposedly better than a carrera GT and every other sports car out there. All BS if you ask me.... can't everyone just wait so that when this pig car gets to the states we will finally all know just how much BS is taking place here.

vegasdude

lol..................maybe the 3800 lbs and the horsepower ratings are not the correct ones...............

Mercennarius

No he wasnt. There was only ONE source that claimed that...and they later changed it. Nissan has been quoted numerous times saying the car was using factory tires and was a production car.

Mercennarius

there have been two independent dynos of the car in Japan thus far....both show the car is actually making about 480WHP at the wheels rather then the crank. In other words its pretty under rated. Not to mention its supreme gearing + AWD+ transmission setup give it an almost seamless power band.

vtecnitian

actually it has been quoted more than once . and there is also a vid of them changing the tires ill try to find it and post it. iam gtr fan but the truth needs to be told sorry

vtecnitian

its been done on dynopacks, last time i checked you need wheels to drive around.

Mercennarius

All restating one source...pistonheads.co.uk. And what does a tire change have to do with it??? They went through tons of tires during testing....all the same production run flat.

Mercennarius

Dynapacks, and the difference is "up to" 5% optimistic compared to a traditional wheel dyno. That still puts the car at more WHP then the Z06.

vtecnitian

i actually dynod my s2000 on a dynapack stock and made 228whp took it to a dyno jet and made 202whp pretty big difference to me.and even if it did make more whp its still 3800 pounds which its trap speed has already shown and that which launch control and paddel shifters. and when edmunds did the 1/4 test it did it in japan which uses higher octane levels than the us does making cars a bit more powerfull over there.

Even if it does prove to be a little faster than the Z06, it is definately not as easy to look at as the Vette. It catches your eye, but not for the right reasons in my opinion.

Mercennarius

There are other factors that could of played into that as well, such as air temp. The dynapack #s of the GTR explain why it is as fast as it is at 3800lbs...

Mercennarius

I believe the Z06 and GTR will best eachother in different areas. Car looks good to me:

vtecnitian

so when the US version hits we will see what is actually packing.

Mercennarius

Magazines have trapped 121MPH in the GTR thus far....magazines have not trapped much faster with a Z06. You can not compare a GTRs magazine time to a Z06 owners personal claimed time.

Japan uses a different octane rating system...when converted to ours it actually works out to be about the same. And running higher octane with out increasing boost/timing will REDUCE power.

yeap but stock to stock to z06 got the edge in my book. just like the nsx had the edge on the r32-34 stock to stock.

Mercennarius

Other then the driving position and the "Carwings" option the GTR has in Japan the cars are going to be identical.

vtecnitian

iam not comparing owners personal times iam comparing their own times with the z06 which apparently edmunds can't drive.
