181mph,
in the video game Need for Speed-Undercover. The one I actually drive, maybe 70. I haven't been anywhere to go any faster.

157

I hit 150 in my 350z
80-90 in 370z (have only had it 5 days)

165 in my buddy's Ferrari 360 modena ...yes he let me drive it. He was driving one of his other cars, lotus esprit, a bit behind me

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.

for those talking about the 155mph limiter not being there,

think of this factor: the speed o is not 100% accurate especially in 100mph+ speeds. If your speed o is showing 160mph, i wouldn't doubt that your actually doing something like 145 or 150.

as a matter of fact, I'm tempted to open semtex's video again and count the lines to see the accuracy.
not saying the limiter isnt there, just a factor to consider until someone can come with a solid factual answer about the limiter. (i cant).

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.

i was at 158mph and it's stock. it will get to 160+ just not at fast as a bolted Z IMO

Let me know when someone hits 180 to 200

I would honestly question the speedometer then (especially if it's stock because the computer limits you to 155). I've done a lot of math on this (as seen in other threads) about how much power it takes to get to certain speeds based on aerodynamics, weight, rolling resistance, power, etc.

Take a GPS system with you next time to see how fast you're REALLY going, because I really don't think those speedos are that accurate beyond 100MPH.

My Honda VTX1300 is 10% too high, which also means that the odometer rolls 10% too fast, and my gas mileage is 10% better on paper.

My Honda Civic is the same way - there was a class action lawsuit over it, where I could have put in a claim - except it had to be on leases and we bought ours...


Having said that, I don't know what Nissan does - if it's something where all the japan cars are like that or not.

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

the european Zs are limited to 155mph. the ones in asia arent as they used to be 180km/h and now they're not.

i've done mine up to 260kmh @roughly 6k rpm. i guess more is possible but the oil temp was off the roof and i ran out of road.

Dude! Awesome video! That takes guts!

:icon18: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:nutswinger:

^ 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.

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............

What if you are below sea level?

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.

You got me! LOL 162MPH? :D

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! :eekdance:

:icon18: Nice job! No cops around down there?

Nop, no cops around that highway ;)... But I want to know if its limted there or I have to put some bolts to reach 7000/7250rpm en 6th

Not sure about limiters on the Z's in Argentina, but up here they are limited to 155 MPH, I believe. Bolt-ons, like exhaust and intakes will give you more power and should push your car even further, but again, not sure if they put a limiter on your Z. Find and try a down hill straight-away and report back. :driving:

You are right about physics and top speed. Some speedometers can be off and a GPS is the way to go.

Havent pushed the car to the limter yet but got it to 220kmh and got my ZX6R up to 299kmh when it had its limiter, havent tested it since i took it off.

only 1049km on the car, not even break in period and you are doing that :wtf2:

Go get a tune and remove the redline.
That's when the real fun begins with mods.
>:]

Don't know haven't tired. had it up to 100 which is fast enough for me.
hows that saying go.
Better to have it and not need it,than to need it and not have it.
To me its about looking good and the 370 does that!

Top speed is kind of a useless concept since it's not real-world tangible in the majority of situations. Unless you're on the Nurburgring, there is no way you're going to hit 160mph on a track in a Z. Obviously you shouldn't be doing this on public streets unless you have a suicidal/homocidal wish.

Did anyone notice the oil temp gauge in the picture?

Haven't maxed out the Z yet, but I had my 2001 ZRX1200R up to 152mph and my 97 WS6 up to 160mph.

Near the famous LIMP MODE... but When was reaching 120°C I stop accelerating... Never went into Limp mode (Or whatever it calls) but I wasn't to far from ir ;)

I ask the dealer before starting the trip back home (1700kms) If I can push it hard, and he said "There is no problem, the engine comes ready, you don't have to wait to do some kms to push it.."
So I follow his advice... No problems happened till now with 5000km :tup:

I agree with all of these points.

I wonder how fast a 370Z is at Road America between turns 3 and 5?

I just recently hit a speed that I never thought I would of... Will never do it again but it was a rush. I told a few people and they just looked at me like I was crazy.. Maybe I am? I pushed it hard and it wasn't done. I was VERY impressed with its stability.

I had a brand new M3 in front of me who said he hit 156. It was the funnest few moments I have had with this car as well as the stupidest thing I have done, in my life, lol.

Conditions were as optimal as they could possibly of been on the street.
