370Z maximum speed specification

"Governor limited" top speed means that the manufacturer put some sort of device in the car, called a governor, to restrict the top speed to a preset level. With modern cars, this is typically programmed into the car's ECU and the fuel injection is cut off when the governor speed is reached to keep the car from accelerating to higher speeds. Governor limited cars are typically physically capable of going faster if the governor is removed. A lot of cars have governor limited top speeds.

"Redline limited" top speed is the maximum speed the vehicle will reach at redline RPM in its highest gear. If a car's top speed is redline limited, it means that the car's top speed is limited by how fast the engine can spin. With different gearing, a redline limited car could potentially go faster.

"Drag limited" means that the top speed is limited by drag forces (aerodynamics being the primary drag force) acting on the car. When drag forces on the car match the thrust that the engine can generate at the wheels, the car will stop accelerating. The car basically just runs out of steam. The speed at which the drag force equals the thrust force is the drag limited top speed.

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

nogoodname · 12-25-2008, 04:17 PM

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!

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.

daisuke149 · 06-25-2010, 06:00 PM

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

spearfish25 · 06-25-2010, 06:38 PM

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.

Cyberium · 06-25-2010, 07:56 PM

It's electronically limited at 155.

JB1 · 06-26-2010, 03:51 PM

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

Jordo! · 06-26-2010, 04:48 PM

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

how much power does your car make? i coulld barely clear 150 in a 997 gt3 at monticello. assuming you have tires in stock diameter, 5th gear redlines at roughly 160mph
