Porsche deliberately used knackered GTR for Nurburgring comparison

Based on this, would you make the educated guess that the GT-R is easy to drive at its true limit, as some have been claiming?
By whom, might I ask?
#182
I said YOU which means you personally don't know how the GTR is at the limit. No amount of reading will tell you that TRUTH, and I already knew what all of the people you quoted said before you wasted your time Control-V guy!
I also never once said the GTR was easy to drive at the limit, and I will just assume that you haven't realized by now I don't need to lie about what was said nor do I care what you the internets GTR warrior thinks about me.

Fine, replace the "we" with "I" or "you." It doesn't really matter. Couldn't someone have some semblance of a clue of how the GT-R behaves based on what I posted?
You were wondering about Nissan's claim of the accessibility of the GT-R. I tried to address that with the 1st-hand driving experiences of those who have driven the GT-R with VDC off and/or tried to take it to its true limit. You subsequently asked if someone was making the assertion that the GT-R was as difficult or more difficult to drive than the ZR1. My apologies if you meant someone else other than me. But I'd still like to know who said it.

You my friend are a ( fill in the blank ) how does that have anything to do with the FACT that other than being AWD systems the 959 system and the GTR system share nothing in common. Come on don't sale ATTESSA-ETS short and compare it to 80's technology. I am sticking up for the GTR here.....LOL...and you make it look worse!
And you don't even understand how the 959's system works because that is also controlled via feedback from electronic sensors measuring steering angle, throttle position, g-force and boost among other things.
So in this post

What we do know is that yaw-rate feedback control, the ability to safely manage slip angle, has been built into the GT-R's AWD system and that front to rear torque split is as much as 2:98 at launch, to a maximum of 50:50.
In short, you know nothing about GTR AWD systems or Porsche AWD systems and bring absolutely nothing to this conversation. Ta-ta.
What to say, what to say? Best I don't say what I'd like to say, or VSEChuck will ban me.

If you would like you can look back thru all of my posts, you may or may not realize that I actually may have a clue to what I am talking about. I have researched the GTR more than most # 1 because I am a car fanatic # 2 I may buy one at some point in the future and considered buying one in the past.
And for those not picking up on what Heavy Chevy said and I elaborated on. The GTR even though computer controlled uses a viscous coupling which can't be 100% disengaged and the most rear bias it goes to is 2/98. With power wether parasitically or applied going to the front wheels at all times the rotational forces applied to them cause them to understeer more than if they were 100% unpowered.

It appears heavychevy and monaroCountry both have more information than we do.
For somebody that complains about cut&pasting, the only information about the GT-R heavychevys got - is pasted from somewhere.

Many 'enthusiasts' can't understand why a car like the Nissan GTR laps so fast despite being laughably heavy and having a fairly mediocre power-to-weight ratio and relatively poor high-speed acceleration. There's been many accusations of 'ringer' and 'cheat' etc. If you analyse velocity-time graphs, the truth is simply that if you can leave a corner faster than the opposition like a GTR, you leave them with a lot to do in terms of acceleration later on, which then leaves them with more speed to wipe off at the end of the straight. People complain about a Nissan GTR's mass, but KE = 0.5mv^2. Hence the amount of work the brakes do is only directly proportional to mass but is proportional to the square of that extra velocity that the opposition needs to catch back up. Even then the extra speed means they have to brake earlier, so they're left trying to make it up in the turns, which puts strain on the tyres and once again we see that centrifugal force = mv^2/r. So directly proportional to m but proportional to v^2 yet again. So it's very difficult to corner faster without cheating with downforce or slicks.
All of a sudden that extra weight doesn't seem like such a problem when it's traction and DCT advantage at the start of straights has other cars accelerating, braking and cornering their tyres off just to stay in touch.
Traditionally with everything technologically even; with conventional drivetrains and transmissions and moderate power outputs, weight has been the main enemy. With non-classical active drivetrains and dual-clutch transmissions, whilst weight is still an enemy, we see that somewhat paradoxically, velocity, or rather the need for higher velocity - as induced by RWD, street-legal tyres and manual gearboxes - becomes a greater enemy wrt the equations for KE and centrifugal force/centripetal acceleration.

Just a few posts ago (#172 & #173) - I didn't see any cut & paste information (just quotes of posts).
Perhaps I'm missing the cut & paste?
How else can someone reference other sources of information to quantify a statement? Is it only more credible to NOT site sources of knowledge?
Basically - the people who say the GT-R can or can't do 'X', without having any actual knowledge, in my opinion are worse than somebody who at least tries to understand something before opening their mouths (or keyboards).

Fact of the matter is there are automotive journalists that drive cars fro tests and still can't tell their head from their butt crack when it comes to a car. So your DE laps don't mean much if you don't understand basics which you clearly don't.
Did you think we were talking about average Joe drivers picked off of any random street? Please, use your brain.
You said HvS was as good or better than Suzuki in this post:

Bottom line:
What we DO know is that drivers that are AS GOOD OR BETTER than Suzuki have driven the GT-R on the ring and not come even close. The same cannot be said for Andy Pilgrim's C5Z test.

Go ahead I'll wait...............
You wasted all that time searching through my posts and can't find a thing that supports your mis-comprehension and twisting of my words.
I'm starting to see why you mis-interpret all of your magazine clippings, because you CAN'T UNDERSTAND ENGLISH. If the shoe does not fit.......
GET OVER IT!!!!!!!

How about you quit deflecting attention from your lack of knowledge to guibo's novel-posts. You have no idea what the difference between push and power understeer is. Are you too lazy to look it up so you can at least TRY to understand what I'm saying. It appears not, so you continue you act like you know what you're talking about when reality is you don't.
Fact of the matter is there are automotive journalists that drive cars fro tests and still can't tell their head from their butt crack when it comes to a car. So your DE laps don't mean much if you don't understand basics which you clearly don't.

I have never disputed your position about what definitions are. I've simply disputed that you have zero experience in a GT-R.
I thought that was quite simple, accurate, and 100% fact. Are you disputing this?
#190
Don't try that nonsense with me Jasper, we both know you had no idea because you had no response to it, no different than you assuming that I have not driven a GT-R when you know nothing about me, am I right?
Don't play coy with me, address the issues head on.

Is there something else you are looking for?

I've already conceeded that the car understeers. I've already explained that there is no power going to the front. We can disagree about this all day long. Until you provide information about the GT-R still applying power on turn-in, I will disagree with you, and I have nothing further to add. I've offered to you - the way that many GT-R drivers have dialed out a large portion of the understeer, and that the nose is heavy (push).
Is there something else you are looking for?

LOL, you really are going to keep playing like you don't know what I'm talking about aren't you. PUSH vs POWER UNDERSTEER characteristics. LOOK THEM UP!! You can dial out a large portion of PUSH, but when it comes to POWER UNDERSTEER, it's not even remotely simple as tires, or factory camber adjustments.
The process of elimination says the car suffers from POWER UNDERSTEER.
Not to mention slip angles that I've mentioned before. To the car that is the same as a loss of traction, which is why when the VDC is on, it cuts power in corners. When it's off the tires still slip, but now the front wheels kick in. Doesn't take much turning input at high speeds for this to happen.
You actually think your car is RWD until mid-corner to corner exit and that is nonsense. The car suffers from POWER UNDERSTEER, moreso than Push. The push can be dialed out with tires, small camber adjustments, but POWER UNDERSTEER cannot, it takes a LOT more effort.
Seems consistent with what the FASTER of GT-R drivers are saying. Sometimes you can use logic to override experience, and this is one of them.
Many people think they don't have understeer and the fact is they aren't pushing the car hard enough to challenge the handling of the car. Running a 2:15 at VIR will feel completely different than running a 2:05 in the same car.
#193
You guys let Heavy trick you into a debate about understeer?
Lets put aside all the CONJECTURE and deal with FACTS.
GTR-7:38
ZR-1 7:38
These are facts of life
Even Monaro said he wont show his face again until someone laps 7:20's in the ZR-1.

ZR-1
- Press tested production car
- 0 prior seat time, especially on the ring
- Official time with a non pro driver in two weeks
GT-R
- NOT a production car, pre-production of a model not even released yet.
- Test drives during official Nissan testing.
- Official time with 5 years of testing and several drivers
Let's see some vids, so Guibo can use his unlimited experience to diagnose them.

What does this have to do with the supertest...
GTR: 7:38

Again, don’t try to force in immaterial points if your going to reply to one of my post. I don’t have ADHD. And I will instantly recognize any point you make which serves no purpose. Monaro has gone off into hiding for a reason, you either need to follow his lead or quit beating around the bush.
