we could have 3 sets of 0-60 times, one for 6MT, one for 7AT, and one for 7AT MM... Maybe putting the 7AT in manual mode is like when Sylvester Stallone turns his hat backwards in "Over the Top". I'm just kidding of course. This thread is halarious, and the best part is other car forums are talking about this too. I "googled" it, and found a Subaru forum having the same debate regarding the 370z... this is great. |

Most of the time metrics are not collected at a sanctioned track - they are collected whereever the opportunity presents. And the timings are tracked with a unit called a VBOX. I can't remember the technical details, but C&D had quite an interesting article detailing the testing equipment several years back. From what I recall, the unit was very accurate - accurate for figures like ET and g's. However, this is a guess here, I would imagine the trap speed figures would be "optimistic" - much like a gtech. But that's just a guess. |

However, the 7at will not out-trap the 6mt. Not gonna happen. Not stock. |

Anyway..... I would be interested in reading that article because years ago I put a gtech in a Mustang that was running high 11s at the time on slicks. A guy that was marketing them gave me one to try out. I figured the sudden launch of dumping the cluch with slicks was just too much for the thing to deal with because the results were not even close to accurate. I wouldn't doubt that that type of equipment is better now but I would have to see identical numbers repeated on a track with real timers to confirm before I'll believe what amounts to a g-meter/calculator can 'figure' down to 1/10s of sec/mph with repeatable accuracy. Maybe someone with real life experience of doing that can chime in. Anyway...... real 106s are being produced and what I'm really interested in seeing are some real track numbers from one with the new long intake and exhaust combinations. If the Stillen intake with pullys and HFC makes as much power on the track as claimed on the dyno I think we'll be seeing some 108s (or more) that won't be debatable. |

Gt-r
Looked inside the GR-R at my dealer and there is no manual shift knob. Paddle shifters behind the steering wheel and what looks like a fancy automatic type console shifter. There is NO Clutch pedal!
So, is it an auto or a manual? Sure looks like an auto to me, although with dual automatic lock up clutches. My 2 cents worth. |

IF you find it so impossible to think that a 370z can put down these times that beat the C5 Vette what do you think of the HR 350z's that run 13.1-13.2. It's been well documented that the HR 350z can run these times so it shouldn't be to hard to understand that the more powerful 370z with a better suspension and rear diff ratio would be faster. Perhaps the C5 has too much torque causing it not to make use of it's power off the line

The most important point to take from this is that it is even harder to screw up straight line acceleration in an AUTO. |

And there are very few HR's that run that low - especially stock. You can't take VeeTec's as being representative of the whole. The vette's real-world times, taken as an aggregate, would be well below the times of the 370, as an aggregate. |

For example, in an article that compared the g35 sedan against the bmw 330(before the 335), amongst others, the best time they were able to wring out of the was something like 14.5 at roughly 100mph. And that was *corrected*. I've got the same car, and with highflow cats, it ran 13.7@102mph. Stock, it ran 14 flat at 101mph. Automatics will be harder to screw up, and they will be more consistent. But until you mess with the torque converter, the manuals will be able to launch harder. That's a fact. In the real world, the manuals will be faster than the autos - that is, until you start running major boost. |

As I stated before the only thing you can take out of this is what they are showing you which is the auto is faster in a straight line. Whether you want to believe or not is up to you. I will believe it since this isn't the only car it has been proven in. And I highly doubt we will ever see a comparison set in ideal conditions. I have rarely ever read of a car being tested on the same day/time with the same conditions and the same driver. It'll almost never happen so this is all we have to go by and usually mag times are reproducible and somewhat accurate. Hell even most above average drivers can best these times as has been proven on many occasions. Last edited by zman1910; 04-29-2009 at 03:29 PM. |

Hard to Shift Paradigms
Believe what you want to believe, but the marvel of electronics and engineering are making the manual tranny old school. Clearly, the Nissan GR-R uses basically a super auto tranny with great performance, so what so hard to believe that some of that technology is in the 370Z auto tranny. Believe what you want, but the times are a changing.

You're right about the technology though, the auto tranny has come a long way from the 3-speed slush boxes of old. |
