I weight my car in the speedway, 3,186lbs are "street weigth"... of corse w/o me in it (200lbs more).

Was this with a full tank of gas, and the spare and jack in place? (I doubt it was since you were at the track) If not then the your 3186lbs is hardly a street weight.

This was with a Touring model 350Z and a 540is 6-spd, tested on differing days of course. The auto in the 540is really saps the power over 75mph, resulting in a high 14's E.T. instead of 14 flat in the close ratio 6-spd of the sport 6-spd model. You ran an auto, a 6-spd would pull away from a stock Z equally driven, as the 130 and 140 mph times indicate, two seconds is a lot of distance at those speeds. The 540's are electronically limited to 155mph, although a Dinan chip can remove that limit.
I don't know what the weight differences are between Touring and other model Z's however, that could have made a difference as well.

I raced a 2003 540i Auto and pulled it pretty hard off the line. He wasn't too far behind when I shut down, maybe a car length but it was still obvious that I was pulling him. I don't know if the manual is that much faster, because I've driven a 540i with that geartronic transmission, and it shifts faster than most autos. I think the auto runs close to a 14.4 to 14.6. I've never heard of a manual running under 14 seconds. I think the Z can take a manual in a drag, because those 540's are geared more towards the highway than off the line.

When you are travelling at a rate of 205 feet per second, every second counts, do the math.
Just as an example, take the delta of each car's capability to accelerate from 130-140MPH. The Z's numbers work out to 7.8 seconds, the 540is to 7.1 seconds. So roughly a 0.5 second difference. Let's take the middle ground of 135mph, so each car is travelling roughly 198 feet per second. Half a second difference equates to roughly 100 feet to make up the 1/2 second to get to 140mph, that's quite a few carlengths if I'm doing the math right (not saying I am, just working this out right here).

My old maxima could run 14.4 on a nice cool, dry day....but on hot, humid days it would be lucky to even break into the 14s...

The point is that the two cars were tested in different conditions, in different YEARS, and probably also in different magazines.
This is the true definition of "mag racing"
Until we get people with 6-speed Zs to run some 6-speed 540i's we won't know what the real outcome will be, so lets stop speculating based on ONE SET of mag numbers.

"Conditions" could allow a Z to be ahead of the 540i in the comparison buy 1-3 tenths and a couple of MPH simply based on what people have actually run in Zs. This fictional "internet race" could then have been swayed in the other direction with the Z ahead at 140mph. The fact is...a car could pull from another very slowly and easily be 2 seconds behind by 140mph....0-140 is a LONG race...
If we were talking about a quarter mile run a 2 second difference would be HUGE. but not in a 0-140mph run.
