370Z maximum speed specification

Flushnismo

Well I'm assuming a 350 and 370 feel very similar at that speed. I'm not trying to be scientific. I'm just sayin..

That's true. 100 MPH in a Buick LeSabre feels faster than 140 in a 370Z.

When I had my G37.. I saw 173 on the speedo and it was not tuned... Wondering if the governer is not always set from the factory? I have been in some BMWs that have blown past the governer as well untuned..

The speedo can be WAY off so I wouldn't go by that. It's possible the governor is RPM based and you weren't quite at that RPM, but the speedo was reading much higher.

You really need to be looking at your RPM and use your gear ratios and tire heights to back your way into your speed. And verify things with GPS (which also has a margin of error).

most speedos read 12-25% high. pretty easy to verify with a GPS unit.

I've only hit 110mph in my Z, so Im still a ways away from finding out what she'll do, theres not many roads around here to open her up..

135 to 150mph is kinda slow to get to. The Z definately needs bolt ons for a smoother-quicker ride to 155mph. But this car sure feels crazy above 140mph in spite of the kinda laggy accel up high.

Went just shy of 155, and the car kept going.. Friend of mine said it would be limited to 110, but that was disproven

Hey guys. Im a "spirited" driver as much as thr next person, especially on the highways.

And i loveeeee speed.

But at speeds above 120mph, and even speeds at 140mph+, a simple BUMP, a simple dead bird on the road, a simple piece of garbage that fell off a truck, a simple MIScalculation in the steering wheel, and it can all be over.

For the sake of life, and ppl on the road....

Please guys, dont go these speeds on ANY public road...

Give me crap if u want... But i have had friends die becuz of speeds above 100mph.. So just my 2 cents..

Dont you tell me what to do!! *Runs to bathroom crying* LOL, but yea, totally agree.

lol...

It is factory limited at 155. if you see more or less on the speedo, it is a small variance in speedo calibration.. if you see a variance on gps, it is a question of calibration vs. wheel diameter (more diameter, faster travel vs. indicated.)

Removing the limit will give mixed results based on a lot of things... wind direction, slight descent or climb on the road, Things like air filter condition, oil, engine condition (is it a tired engine over 100k miles and more exhaust out of pcv than the exhaust, etc...)

The drag coefficient is also a factor... .29ish can be helped by adding in a full undershoud to limit under-car air turbulence, and dropping the car enough to limit under car channeled air.

"Tuning" the tires ( properly sizing front and rear tire diameters) to a near neutral cord line relative to path of the car will also reduce drag or in some cases remove float. (bigger rears making more downforce but creating much more drag, or front wheel large diameter causing float and increasing under car drag, and possible dangerous condition at high speed.

Other things like tucking the side view mirrors ( or removing them all together) drastically helps at those speeds

When at the track, ive gotten it to sit at 155 quite easily... when i removed limits and twin turboed it, i was up to 184 (gps).. but that wasnt a max out, just a quick top out on a pull. had i sat on it, i might have gone much quicker.

The car is quite stable, but not practically meant for sustained max speed.

that said, ill throw in the disclaimer..
you should never drive faster than the speed limit on public roads. Any driving of this nature should be considered unsafe without the express consultation of a professional in this field and in an approved venue for such activity. high speed driving requires reinforcement of the vehicle to avoid catastrophic failure of oem components.

when I shop for a car, I do pay attention to how much power does it make thus knowing is it a good engine..

but I don't really pay attention on how fast it can go or what's the max speed...

cos I know 1) I won't be able to reach that speed, and 2) it's too dangerous to reach that speed.
