Top Speed

tbonesteak

156 in the s2000
135 in the 350z
135 in the maxima.

350 felt like a lexus compared to the s so im assuming the 370 will do 165+ no sweat unless it's gearing limited. The 350 at 135 had a lot more juice left but i ran of runway. 156 in the s i am lucky to be alive. i thought the entire car was gonna fall apart.

Most cropduster biplanes cruise at around 60-70 mph by design, so once you're up over twice that speed on the ground, you know things can quickly get "problematic".

I don't look at my Z as a plane without wings. I like its maneuverability and quick reflexes. I like the way I can launch right up to the speed limit while most cars are still getting through the traffic light.

But I'm a few cars past the time when I'd treat a 3-lane roadway like a set of moving traffic pylons. Nowadays, at most when I'm in traffic, I'll zoom some lamer in the passing lane, then clean off his windshield for him with my spray. (Some kids in the Acura forum spoke about tossing pennies up through the moonroof, but to me that's criminal mischief).

The nicest thing about having a car so much better than most on the road is ... I don't feel the need to prove it. And getting to a destination ten minutes quicker just means that much less time spent in, and enjoying, the car.

Electronically limited. The gearing is fine. There's a thread on this forum somewhere with the theoretical top speed (which I believe was 198MPH) based on gearing and red-line.

But this car won't see 160+ without mods. Stock it'd be lucky to see 160 at all unless you're at sea level. I think with full bolt-ons it will see 170-ish speeds.

Well, you can use a GPS system next time to see your speed. Most phones these days have that built in. Mine is VERY accurate. I've used it a few times instead of the speedometer on long trips.

It's VERY common that stock gauges aren't accurate. That's part of the reason people go with aftermarket gauges. Tachs obviously being the most popular since those are the time critical elements. Since speedometers aren't usually important to racers, they're rarely replaced.

The signal they get from the computer is usually right, but the mechanical electronics and/or microprocessor in the factory gauges suck. Most GM tachs are as much as 500RPM off at any one time. LOL

i've heard all cars are capable of going over 170mph ,that is pushed off a cliff with enough drop,galliao proved that centuries ago

vehl

^ and that can be done without using much fuel..

Just to throw it out there for the speed limiter debate...The M3's are known to be up to 8% fast on the speedo. So it is a possibility, like mentioned already, that you may not have actually gotten to the true 155mph mark even though the speedo read so.

That being said, on my race on a totally legal racetrack heading towards Houston, I raced one of yous guys and we I was barely gainging on him and I was showing a couple clicks over 160.

Crash

Yep. I'd like to see it with a GPS before I believe it. Supposedly the last owner took my car up to 175MPH, but that could have easily been 160MPH. Who knows how accurate these gauges are.

Sometimes when I come to a complete stop, my Heads Up Display still says 2 MPH for a second or two and then quickly rolls down to 0 MPH. LOL

well i gone the speed of light not something to brag about............

The odometer and speedometer on the 370Z is extremely accurate. Just did a 600 mile trip with a GPS (by the way, a phone GPS will not be as accurate because it is using cell towers and not satellites) and over a 400 mile section the odometer and GPS read within .5 miles of each other. The speedometer (which is directly related to odometer accuracy) was never off by more than
.5 mph up to triple digits.

Crash

You got me! LOL 162MPH?

Were you going over 120MPH? The argument isn't about how accurate they are at normal highway speeds, but whether or not they're accurate above 100MPH. My Tom Tom and Garmin both tell me my Speedo is accurate at 60, 70, and 80MPH. But above 100MPH is another story.

Remember that the speed is registered by picking up pulses on the transmission. There's no physical connection to gears. So the faster you go, the more accurate the speed sensor must be.

Hi, I'm from Argentina and I have a 370 6 MT Black Diamond, LSD, 18", Sync Rev, Bose Audio System an electrical/heater sits, a mix of Sport and Touring version (Is what Nissan brings here...)
Sorry to resurrect such an old post, but... I have trying to know if my Z is limted or not... I'm at sea level and my top speed reached was 265+km/h (165mph) not GPS tested, 6th@6100rpm and won't go any further. So, I have 1400rpm to reach the 7500rpm factory limted. Is it posible to reach it stock?

Sorry for my bad english...

I've only got mine up to 100 mph, I'm too paranoid, even with my Passport!
