370Z maximum speed specification
 

Hi

Has anybody seen a quoted maximum speed for the 370Z? I am sure there is a limiter from the factory but I can't seem to find the max speed specification.

Thanks for any info.:driving:

I've read several times that it is electronically limited to 160 mph.

if it is like the G37 it will be 155 mph don't ask me hoow I know ;)

^^^Hey wheres that top speed run ya promised us in your G:mad:


:driving:

I read that it's NOT limited electronically. It's limited to 160 by DRAG!!! I'm not 100% sure how accurate that is, but that's what I read in a magazine while standing in line at a Best Buy. That speed makes sense... My Trans Am was a limited to about 175-180 by drag and it had a lot more power than this.

Remember where you read that from?

I actually have that magazine somewhere around here... I think it was road and track, but I can't recall off hand. I'll find it and let you know.

EDIT: If anyone recalls, it's the magazine with a Yellow Z on the front and it says something like "Best cars of 2009".

The magazine with the yellow 370Z on the cover was Car and Driver January edition.

Thats it!!! ( I think )

what does limited by drag mean.

^^ coefficient of drag or something?????

thats what I was thinking but I know the guys that got the cobb for their G are now going aver 155 mph

Re: Gov ltd vs Drag ltd - Car and Driver FAQ - Car and Driver Forums

that's what i was thinking

drag limitation is when the force of the car and the force of the air/surroundings equal to each other..........
i should of mentioned this before..lol....i learned it in class...ha

BTW, That's FANTASTIC information for anyone planning on modding. That means there's no limit in the computer we have to disable. And it also means that slight mods we put on the car will get us over the 160 mark even before we tune the car! :D YAY!

My Trans Am's limiter was originally set at 153... I remember the first time I buried the needle past 155 (which is where I ran out of numbers and then one last mark for 160)... Ah... Good times... :)

cool info

I just want everyone to know that if it is like the G, it is electronically Limited to Approx. 155 MPH, and i say Approx. since i have no way of knowing for sure because my G burries the needle to where i would assume 270 KPH is @ 6200 RPM, now i assume this is a speedo calibration error since everyone has slightly different numbers. It won't move any more but it climbs there fast, so i am sure drag did not increase so fast as to stop it, nor would it stop identically at that same RPM everytime.

Correction!!!

The Z is NOT drag limited. It's electronically limited at 155mph. My s2000 which had a drag coefficient of .35 (very bad) was drag limited and that thing went to 156 on a flat surface with 18" volks. The Z has .29 drag coefficient (NSX level meaning GOOD) and has 100 more horses. I've taken my Z to 155 (at a track ofcourse) and it definitely is not drag limited.

personally i'd be disappointed if the car was limited by drag to only 160mph...

It's only limited to 160mph by drag with the current engine power. If you SC or TT, your drag limited maximum speed increases too. Whether or not the car has an electronic limiter, I'm not sure. However, one 'regular' of the site claims it went over 160mph.

It's electronically limited at 155.

Drag limited @ 173.75 mph (278km/h) according to this video (car in the video had it's electronic limiter disabled):

If there is a limiter, anyone adding enough power to seriously push the top speed will be able to shut off the limiter with their tune... ;)

Did Monticello Motor Club NY the other day (3.5 mile) which has real long mile plus straight- just put it to the floor and ran up thru the gears- on previous track days really no idea on speed focus on tach - so I down loaded IPhone top speed app and let it record- on the street/ highway was very accurate- on the track it recorded top speed of 166.9 MPH- a little suspicious of accuracy but on the the street is was nuts on so not sure why higher speed would introduce error- understand electronically limited 155 or so - assume the "acceleration" momentum would carry thru the fuel cut off - I still doubt 166.9 a bit but I was flying- only mods- Stillen G3 CAI, Stillen Cat Bac, Stillen 19 Oil Cooler, Hawk Brake Pads/ SS lines & Blue

Here is pic of IPhone

It says in the manual (99% sure) that the Z is electronicly limited to 155mph. With the governor disabled, I'm sure it can go a lot faster.

It means it ain't got enough H.P. to go any faster.

Yes it can, at least 173 with the governor disabled.

its electronically limited at 155mph just like ALMOST every car sold in america theres no way its drag limited at 160 i would have to say at least 173 my e46 m3's which had the exact same HP (333) top speed was 183 with out the limiter and im pretty sure it had a greater drag coeficient.

It's got a limiter. When Technosquare tuned my ECU they removed the top speed limiter which obviously means there was a map in the ECU for such a thing to begin with.

The end.

If the car is "drag limited" that means there is either a deficiency in aerodynamics and or horse power. And aerodynamics goes farther than just the drag cof but I’m not going to go into that. If the car is “electronically limited” at 155mph I don’t doubt that it could reach higher speeds but the real question is how staple / safe is the car at those speeds. You have to ask yourself why the car was “electronically limited” at 155mph and the answer is probably because the car isn’t very safe beyond that speed due to aerodynamics. My MS3 is also “electronically limited” at 155mph and has a drag cof of .31 (pretty decent) It feels plenty staple at 155mph but I wouldn’t trust it much beyond that nor would I want to. Imagine getting clocked at 155+, I doubt you'll see your car again lol!

I am pretty sure that the car is computer limited to 155 because it is sold with W rated tires. I think their safety rating is right around 155 because they can't dissipate as much heat as a Z rated tire.

not saying i was driving or anything :P ...but if i could hit 152 in my 04z i think the 370z could easily break 160 (if it wasnt for a limiter)

When drag = thrust, the car can go no faster. Thrust is the reaction force of the wheel torque at the road surface. At slow speeds this force is much higher than the aerodynamic drag, so the car can accelerate. As velocity increases, the drag increases by the velocity squared.

It must of been an 04.5, as those cars are F-L-A-W-L-E-S-S

While I'd love to believe that your mazda feels stable at 155mph, the electronic limitation is more related to what tires they put on the vehicle. I believe the tires on the Z are "W" rated, so they limit it electronically to a few mph less than the rating to make sure it will handle the speed okay. Y rated tires (which you would need if removing the limiter) are a lot less common, and I'm going to assume more expensive. Not to mention no need for the average owner to take this thing beyond 160+

The sport package Bridgestones are Y rated, fwiw. Not only are Y rated tires common, they're available at very good prices. Hankook Ventus V12s are Y rated and about $220 a tire.

I have to agree that top speed worries are a bit stupid unless you're building a racecar for specific, long-straight tracks.

May be a dumb question but what's an 04.5? Lol. I was talkin bout my 04 350 enthusiast ( <3 )

Governor limited at 155
