GT-R runs, this time w/o speed limiter.

http://www.youtube.com/watch?v=flJT8GvoM78

Note: Ford GT on that board has 850 hp.

 

.1 secs slower than a GT2?

Sounds about right.

Not bad for a 480hp car that weighs 3800+lbs.

What is hp/weight of the GT2?

Perhaps someone like Monaro can explain why a car of this hp/weight ratio can go around a track faster than Lamborghini LP640? Doesn't it have better hp/weight?

 

No way ! It's a "ringer".

 

On another note... That show doesn't really live up to the original, in my opinion.

 

It's funny. After the GT-R with limiter ran last year, mC was copying and pasting this to various boards:

"Notice that the Ford GT comfortably trounced the Nissan GTR in this test, thats twice the Ford GT has beaten the GTR. So how can the GTR beat the Ford GT around a high speed track like the Nurburgring by a margin of around 13 seconds. Porsche and Auto Sports time of around 7:50 fits perfectly with the Australian Top Gear time.
7:29* -- 164.68 km/h -- 2009 Nissan GT-R, ??? PS/??? kg
7:42* -- 160.52 km/h -- Ford GT, 550 PS/ 1521 kg
Top Gear Australia Track Laptime
1:08.80 - Ford GT
1:09.46 - Nissan GTR
1:11.69 - Porsche 911 Carerra S PDK"

Sport Auto NRing test results:
Ford GT (344 hp/tonne) - 7:52
GT-R (273 hp/tonne) - 7:38
The GT-R does beat the Ford GT around the Nurburgring by ~13 seconds.


I have never seen him acknowledge that the Ford GT in the test had 850 hp, even though they state that it did. @ 4:38 in this vid.

At 1:57 in the video it says "whipple supercharger" on the side of the supercharger, is that stock? Also, does a stock GT shoot flames out the back like this one did at 3:59 and 8:13?

Moral of the story, it's not a stock GT...

Peter

 

Nope, standard GT's don't say "whipple" on them.
Looking at the suspension, it doesn't look stock either. The shocks appear to have adjustable collars and attach by rose joint to the frame. Definitely not standard. Tires are also not the normal Goodyears for this car. They look like P Zero Asimmetrico's, which are an R-compound tire.

I can't believe someone would use this as evidence that a limited GT-R is a slow track car. Oh, wait. Yes, I can.

 

Actually, I disagree. It appears that track is flat, with short straights and tight turns...

The cornering of this car (although it weighs almost 4000lbs) is amazing, and the low-speed acceleration is lightning fast (due to the transmission, and gearing).

If anything, I'd say it plays into it's strengths a little bit.

I'm curious, though - why do you think the track doesn't suit the GT-R?

 

It does shine on courses when most cars have to lift, or stay off throttle for periods of time, when the GT-R allows you to apply throttle.

 

Again it looses out to the GT2, whereas Nissan's example was comfotably ahead of the GT2.

In a short and tight track like this the GTR should really shine, not the long and high speed track like the Nurburgring.

 

Fixed. Makes complete sense now.

Care to explain?:

 

^ Based on the above example (and my extensive knowledge from watching NASCAR for years ), that oval would be a great example of a long sweeping straight, but the corners require most vehicles to lift. If the GT-R can get through the corner while lifting less (sometimes not at all compared to other cars), the exit speed is a lot higher, which might net you a slower topspeed, but a higher average speed.

 

So Nurburgring = oval?

 

Aparently the GTR isnt the best car to take around a bumpy track or road.

Speculations!!!!!

Can you also explain the other supercars in the group and how the GTR can keep up with them? Also can you explain how most independent tests can only achieve a 7:50's while one of the best ever driver around the ring can only achieve a 7:38?

 

That's not an explanation, mC. That's a question.
You were saying the GT-R doesn't stand a chance, gets demolished on a high-speed track. An oval is a high-speed track, no? Look at comments by others who have driven the GT-R:

"To drive it flat-out on a circuit – even one as wide and safe as Bedford – is to understand precisely how it can be so fast around the Nordschleife."
--Evo

"The Gumpert and the GT-R share a feeling of being constrained by this circuit [Anglesey]; both require the Nurburgring or even Le Mans before you can really stretch them."
--Car; Anglesey is far faster than that autocross course

"[after Karussell] Interestingly, this lefthander that the Porsche is going into now, the Nissan has a slightly higher apex speed, because it's got this incredible stability at high speed.
[Hohe Act to Eschbach]These direction changes, again, suit the Nissan. In between 70 and 100 mph, the Nissan likes this stuff.
[Pflantzgarten 1] Can't split them here, but you're waiting to get on the throttle and the chance arrives sooner in the GT-R. It likes these longer, open radius, faster turns."
--Drivers Republic

After reading all of that, what makes you think the GT-R prefers a shorter, tighter track? The car is pretty bulky and heavy, so it should be hurt on a tight course and at low speed where hp/wt is more relevant; at higher speed, aerodynamics and lack of lift (and other confidence-inspiring factors) come into play. On top of this, the GT-R has a relatively long wheelbase, which hurts in tight corners but helps with high-speed stability. And the more shifts there are, the less time the GT-R loses to more powerful cars.

Aside from the GT-R pulling more g's than either the LP560 or the ACR (tuned specifically for that track by an ACR engineer), look at the comment by the race driver: he says the Viper's gearing hampers its speed. This reaffirms the ACR's performance on DH straight: it can't pull hard in 5th, so the driver chooses to keep it in 4th. And that's how the GT-R can be that fast compared to an ACR on the straight, besides the strong headwind.


I believe it is too much for him to understand.
It's like if you two guys studying for a final exam. One guy does his homework, studies weeks in advance of the exam, gets an "A." Another guy doesn't do his homework, studies the night before the exam, gets an "F." According to monaroCountry, this second guy is correct to cry "cheating!!"
