This is one very possible, even likely I'd say, explanation as to the large variation in track times that have been seen. Porsche lying, not trying or not being familiar with the car is simply a much more extreme and remote possbility. Just out of curiosity do you think Suzuki san could get close to any/all of Rorhl's times in various P cars at the ring? I sure do. |

I just don't buy it that such a huge variation in output is here in one car. And isn't funny that Porsche just happened to got the slowest of all GTRs, remember that the one used by DR wasn't a rocket, a normal 997s with DCT beat it in acceleration.

As far as that particular comparison the 997 PDK put in a great drag strip showing but the GT-R made up for that on the track with its great handling AND super sticky Dunlops (again good for roughly a half second a minute, right). As well I'd be willing to bet they did not use the warranty voiding LC in the GT-R! On a mostly unrelated note is was funny how they were talking up the PDK dual clutch transmission so much and noting that it made so much difference with its shift times in the drag race. Perhaps they forgot that the GT-R also has a pretty advanced dual clutch transmission... On the trap speed variation in the GT-R: We've been through this before...I think the observed range for trap speeds is about 115->125 mph. A couple of lists have been posted here but I can't seem to locate one presently. Now certainly all of these test were not identical, controlled, under identical conditions, identical temperatures, identical methods, etc., etc. So you get natural variation, some systematic, some random. But using the very rough trap speed vs. hp conversion ("estimate" might be a better description): hp = weight x (speed / 234)^3 We find the hp to range from 475 to 610. You have already told me that 50 hp is not a big deal, abnormal nor dishonest, but a 135 hp range. Come on. Just for kicks the M3 results in our own very extensive database shows a 111->115 trap speed range this comes out at 406->450, a mere 44 hp, or about 11% of quoted. The GT-R is 28% of quoted. This is called VARIATION. |

I didn't know that it had Dunlops on that occasion, where did this info come from? Either it actually backs up my position, that the GTR with Dunlops is quicker than a GTR. The GTR at Silverstone had a tried clutch according to Chris but I don't know if LC wasn't used, though this is irrelevant to the lap time it did and the fact it was slower by 10mph compared to the GTR and LP560 proves it's output wasn't excessive.

If you want to work the figures to your own ends then by all means be my guest but most people know that both cars are on average producing outputs with in the tolerances expected for manufacturing. P.S. BTW you are still not giving an answer to my question, I will repeat. 'Given that most tests conducted show the GT2 and GTR too be very close in track times regardless of the average speed of the tracks in question, do you still feel that Porsche and DR's times for both cars should be so varied?' Please answer the question. |

I am not at all surprised by this. You can disagree, call it cheating, but for what ever reason Nissan chose to give the GTR a comfortable 10% more power in the GTR than it quoted.

Two others on the list are very important to the time Nissan achieved in comparison to any other, one is Suzuki's knowledge of the car and his ability and the other is the huge effort placed on Suzuki to achieve the result needed at all costs. The perfect day and lap simply made that time possible, as I said previously, god knows how many laps in the mid 7:3X it took to get that magical 7:29. Next, everyone need to look over all the data so far compiled about the GTR vs others to see that with the possible exception been the Porsche car the GTR's performances have been pretty consistant with it's rivals, as was the same when DR tested to the two. On average the GTR is within a second of it main rivals and never ever a full 16~17s slower than the GT2. |

The Transmission cost $25,000 Dollars
and after 30 launch controls its usually destroyed They have a lawsuit against them from some of the owners who were not aware of that LOL and Nissan doesnt want to pay for it and completly wipe out there profit margin

Hey guys, you are all wrong.
I got 7:28 in the Ring with the GT-R in Grand Turismo 4 on the ps3... looks like they weren't lying after all. Chill.
