R&T: GT-R vs ZO6 vs 911
The GTRs straightline performance does seem a little unpredictable. I thought this may be a JDM vs US-Spec difference at first but I've noticed this in the past with stock GTR ECUs. Skynet decides to run a little faster some days than others.
I've heard about this but I'm holding judgement until I see the scans.

tell you what..you seem like an intelligent chap..if you manage to join here again. Man up and PM me before you start posting or this banning will continue for a very long time.
Oh im sorry. i was just trying to articulate how amazingly insane the CGT is. and the F bomb was the best word.
but i apologize for that.
Mag racers FTW!

It doesn't matter, 90% of the owners of either cars wont be able to drive them at their limits. Porsche will out perform them on the racetrack in real race cars, (something Nissan doesn't know about) and it will be a happy ending.
(Real racing, not this magazine/D.E. test crap.)

I don't have any bias. If you believe that a Nissan has equal workmanship than the Porsche so be it. Quality, is clearly tied to everything that Porsche makes. It is not easy to convince me that Nissan builds cars for the masses "except" this one car. Think about it. There is no way to bring the philosophy borne by Porsche and apply it for one vehicle without tremendous cost. It either is or isn't. As such, no one can compare the cars on a qualitative basis and conclude they are equal. Other than magazine writers but they aren't buying these cars anyhow. . .
I say that as a person driving one of their trucks daily who "ownes" two (2) turbos. No rattles, squeaks. Not a sound. That continues after 30k, 60k etc.
Look, you're on a 997 tt forum, but I own diverse group of cars. The Porsche is not the fastest car I own it is the "best" car I own. I am saying that because it is fast, engaging, handles awesome and the interior is, well , perfect. I have had/have a few Japanese cars GS 430 (Second iteration) and the SC 430. Lexus is a great car, but infiniti, Nissan's top line not even close in build quality to Lexus, which, in my opinion surpasses anything produced by Nissan. Porsche is again wayyyyy ahead.
The argument really turns into something akin to My Evo is faster than your Porsche. I do not let magazines make car buying decisions for me nor do I really care that people want to aggrandize the Nissan for introducing something "Porsche like". Japan is best at copying things I am sure that the GTR is the best Japanese 997 tt made. For me, there is no substitute . . .

I've been asked by 'Control It' to post an honest opinion here. So here goes:
I’ll start by saying that I think Millen put in a sound 98th percentile lap in the Z06. Maybe if everything went exactly right, he could run 2:00 dead but motorsport only ever goes perfectly in your head. From experience of driving earlier ATTESA systems, I think there are aspects about this track that gave the GTR a larger than usual advantage. Ordinary AWD gives stability and traction but ATTESA gives stability, traction and RWD turn-rate when needed. This allowed the GTR to turn well in the single-direction corners and cope easily with the left-right complexes and Esses section and pull well out of 2nd gear curves. Neither of the other 2 cars possessed all these abilities. It’s also possible in sections like the Esses that the GTR’s more neutral weight distribution allowed it to handle more favourably than the 997TT. The yaw-sensor and newer electronic stuff – that I don’t really understand because they’re new – may also have provided stability advantages in such sections.
On a track with larger distances between higher-speed, single direction turns, I’m sure that times would have moved in the Z06’s favour. Different horses for different courses.
Here are some interesting times from a 2007 Super Lap Battle at Buttonwillow:
http://www.maxrev.net/index.php?loca...meattack07.htm
You’ll see that the GTR time is very competitive with modified cars running in the ‘Limited Class’ – table near bottom.
You’ll also see that Car and Driver only managed a 1:58.3 with a 500kg Ariel Atom 2 packing 300bhp. All of a sudden the Z06’s lap time doesn’t sound so bad does it? In light of this I’d almost disbelieve the GTR’s time but sand-bagging can only make slow times not fast ones. You'll also see that Millen was faster through the Cotton Curves in the Z06 than C&D (bottom of link above) and made higher peak speeds on the main straight. Sand-bagging? No, it just wasn't a perfect lap. Anyone who really does a lot of tracking should know that perfect laps are few and far between, yes?



As regards the straightline pace. The GTR times are significantly slower than elsewhere. This could be down to US mapping for low-grade gas or it could just be tolerances at work. I have confirmed with the editor of Road & Track that the US GTR has a 7000rpm rev-limit and redline. The JDM version has a 7000rpm redline but a 7500rpm rev-limit, which helps in the 1st-2nd-3rd transitions by keeping the needle in the sweet spot.
Other observations? Frankly I’m surprised that the 997TT is only 0.1s, or about 6% slower than the Z06 from 110-120mph. Looking at the gearing, weights, drivetrains, power and rpm delivery, this doesn’t seem to figure but that’s motorsport for you.

Well, look, if you believe that the GTR is a better car a "bench mark" ok. But, riding around the block is different than engaging yourself in the car.
Here is my test for you to really think about. . . Same money, so that the financial issue doesn't drive your decision. GTR or 997tt? If you chose GTR you need more seat time in a Porsche.
In my mind there is no doubt that the 997 is a better built, better looking and, yes, faster. (look at traps and weight of the GTR vs. 997tt)

Gentlemen,
I am taking a break from our regularly scheduled debate and flame session to make an announcement.
I have not followed every post in this thread but from spot checking it, I can see several of you may be violating our guidelines regarding personal attacks.
Rather than lose some of you, I am rolling back the clock and starting over by unbanning Z07/CaneAndAble.
From this post forward, this thread will be monitored closer and if personal attacks are made, there will be immediate bans.
I am asking you all to try to maintain a civil (albeit 'lively') discussion without it lowering into name calling and insults.
carry on.

I've only read a couple of posts but get the gist of the "debate". I do agree w/Minid (sort of, which is scary!), why didn't Porsche get to use the GT3? The 997 TT is more of a touring car (no offense to owners) than a track car. At the end of the day (or debates), we're all the benefactors of great cars being made by multiple manufacturers.
