Going to the dealer in 45 mins to spec out the car. I have already spent hours speccing it at home over a few whiskys .
Only issuse is that Sport Exhaust isn't available until Nov. So, my Sept build may have to be passed on. As long as I get the car by March, I'm good. It's getting up there, but she should be pretty sweet. Last edited by devo; 06-18-2008 at 02:07 PM.. |

Easy Bruce. I wasn't agreeing or disagreeing with anything or anyone. Just pointing out variability due to driver. Isn't that pretty clear? I doubt that Nissan's #2 driver is the engineer who spends his days behind the telemetry computer. That said, I am not saying that Horst's time can be pulled down by another 15 secs. He's obviously no slouch.

I can't decide.
This makes deciding that much harder:http://www.evo.co.uk/videos/planetev...rsche-911.html This is the base Carrera (345 hp) without Sport Exhaust. |

"I still think for outright driver involvement the manual is the better bet." "It's a much better system than BMW has got in the M3. Smoother, faster, and just more responsive and more engaging to use." I wonder how and why it is that PDK is that much better than DCT. You have a really though choice with the tranny--given you won't be able to test drive one unless you are willing to wait until next year.

Semi-race sneakers get you slightly higher cornering speeds in every single type of corner, but where they really shine is down the straights - or any other section of track where you can mat the throttle. Reason: You come out of each corner a little harder on these tires because of slightly higher cornering speeds plus the ability to gas it earlier, and you hold that speed advantage right down to the next braking point. The fat-second-per-minute "rule" is more a reasonable guideline, but I can say that with minor variations, it's held true for both myself and a number of other folks I know who've done a few K miles on various tracks. All this of course presumes aggressive factory rubber to start with. It also presumes performance cars, as I'd assume a stock Camry (or somesuch) may create some interesting camber numbers when subjected to such high G loads. You might need to fasten roller skates to the door handles. Bruce |

Appropriate balance/skepticism.
Smoother, faster and more engaging in comparing PDK to M-DCT simply reeks of not only fan boy-ism but absurdity as well. M-DCT is about as fast and smooth as it gets. Any improvements there would be pretty miniscule. That being said I'm sure the PDK system will be every bit as good. Heck it may use much of the same hardware or technology. |

It makes me laugh when some people think the tyres is the sole greatest improvement one can make to your time, it's only a factor among many to achieving that goal. Why do manufacturers spend countless hours hammering around tracks like the ring to fine-tune their suspensions when a simple tyre swap would have achieved the same results, job done. Sorry but it doesn't happen that way. |

I personally have no clue as to which of the break-a-snake's-back or two-corner tracks would show a greater difference between times due to choice of rubber. I'm tempted to say the two-corner track would show a larger difference than the serpentine track, but admit that's just a feeling. In all probability, there would likely be either little difference or none at all. You need to think about this. Quote:
Bruce Edit: PS - If memory serves, wasn't Rohrl screwing around in the 7:49 7:50 range in a Turbo maybe three years back, before hurling those PSCs on there and going 7:40? Porsche then made them optional on the Turbo, so they could properly say a stock Turbo could best the Z06, right? Just an example, but it mirrors my own experience.

I'm willing to bet that set of aftermarket swaybars will make FAR more difference on track than set of more performance oriented tires.
Take two M3s. One with all seasons and one with PS2. It is much more likely that a car with aftermarket swaybars (or set of bilsteins) running all seasons will lap faster than stock suspension car with PS2. That is not to say you should cheap out on tires, especially on these cars. Tires are a good mod, but not the best. |

On non sporty handling cars with really flimsy sway bars perhaps the sways would buy you more. Would be an interesting experiment. However, I think there are probably some real track nuts here (enigma?) who could answer this pretty definitively without having to do the testing. |

It's great to see Swamp and Bruce in agreement.
OK swamp & Bruce first, the 8 seconds Bruce is talking about I believe referred to semi-race compound against PS2 which I very much doubt will yield that kind of improvement unless the suspension is retuned to take advantage of the extra grip available, plain and simple. Now what malter2.0 is talking about might improve the car's ability to take the corner as quickly as the tyres would on their own though I would be less sure of this. To me suspension and weight balance makes more of a difference to confidence and thus lap times than anything else, of course all other things remaining equal. But as always we are miles off topic and should get back to the discussion in hand. |
