We know that the Z is lighter than the G37, but does anyone know about the gearing: tranny and rear axle? As you all know that can make a huge differance.
The weight of the G will hold it down some, so I would predict that most magazines will get around a 13.5 - 13.6 with a high RPM launch. By far the most important metric for the street is the 5-60 time. It will be interesting to see how fast the G is from a rolling start.

Also, where did you hear the new 3.7 has 40 more wheel hp? The new 3.7 as far as I can tell will have about 20 more wheel hp compared to the new HR in the Z.
My prediction based on documented G sedan numbers is 13.7 at 103. I'd be pleasantly surprised with anything less.
In terms of gearing, the new G has the same gearing as the 07 sedan. Not sure about the 07 Z.

I was thinking about this earlier today. Ironic there is a thread about it.
Take off the spare tire, and remove the back seats: 13.2 with good shifting, 13.3 easily (e46 M3 was mentioned which is also my basis).

Why would they need a high RPM launch in a car such as a G35? It's no 4-banger would no low-end power.
As far as gearing, its more aggresive than the current G35 & 350Z; Final drive for both auto and mt is 3.7, while the G/Z have a 3.3 for auto & 3.5 for mt.
Even though the 07 Z is lighter by about 225 lbs than the G37, the power the G37 makes overshadows the additional weight. (G37 has a better power to weight ratio).
Like I said, this is all speculation, which could matter less, but I expect it to do atleast 13.4 @ 105 mph.

The HR in the 07 should dyno around 265whp, so 265hp/3339 results in 12.6 pounds per horsepower. The g37, at 3682lbs and ~290whp, carries 12.69lbs per horsepower. So don't expect a big jump from the current 07 z.

The 07 Z Base does weigh in at 3339; the 08 G37 Base at 3616.
And the 07 Z Tour/ Grand @ 3404; the 08 G37 6MT/Sport @ 3668 (3682 for Journey w/ Sport).
So if im comparing "apples to apples", either way the difference is weight is usually 275 lb.
I agree with the fact that the difference will not be big. If anything, I just expect the G37 to be few tenths quicker than the 07 Z and trap 2 mph more.
I wonder what VeeTec would do if he got ahold of a G37. As far as now, everything is speculation and we will just have to wait and see what the G37 can really do at the track/drag strip.
I honestly do not like the direction Nissan is taking in regards to weight; they seem to not see the importance of a lighter vehicle when it comes to performance.
I expect the next-gen "370Z" to be atleast 100lb heavier than the current.

skaterbasist ftw. Same/Slightly better hp:weight than the 07 Z (which does anywhere from 13.3-13.6), except the G has a better powerband throughout the entire rpm range, and more aggressive gearing.
The G37 should beat the 07 Z slightly. I expect low 13s for good drivers, mid 13s for crappy drivers.

The few road tests there have been so far all have mentioned that they didn't think the G37 was quite as fast as the 335 in a straight line. The 335 does 13.5-13.6. If the G37 was a low 13 car, I think you'd be able to tell.
I would love to see low-13's but in reality my 04 was fast enough for me and that ran in the 14's, so whatever this is will be good enough as a DD.

335I pulls of 13.3. Maybe its the TT effect on 335I why it feels faster?
With this amount of engineering lead-time to see the competition, i would expect nissan to have done their homework.
