Whats the story on eliminating the eletronic speed limiter. I would think this would be one of first things some people would want to do . Is there any easy fix. Maybe a performance chip that does that and more.I looked deep into this forum and saw no mention of this type of mod.

 

The speed limiter is set at 156 stock. If you plan on going faster than this make sure its on a track.

 

it is limited by the ECU. tho Im not too sure how much more the car has before drag halts it. but anyway, you need a aftermarket chip. which to my knowledge isnt available for U.S. Zs yet. after that, its no problem.

however I could care less, as Id imagine alot others would too. first off
that will NEVER happen. the Z can not dream of taking a turn at 156+mph. and no track has a straight away long enough for it to happen. meaning youd have to do it on the streets, which is where everyone thats hit 156 did it. basicily top speed is a bragging rights kinda thing, nice to know you could do it, but you really never will. and as someone thats done 135 and ran out of road, 135, 156, 180, whats the difference? their all DAMN fast. and your pretty well gaurenteed death if you mess up.

or hell you dont have to mess up, youd better have aftermarket tires, cause I think the stock tires are rated to 130 at best. after that your on your own.

 

I know I'll probably never bump the current limiter,but it's just the idea of having a performance car with any type of speed limiter.It just goes against my old muscle car mentality It reminds me of my pick up truck [ limited 108mph ]

 

Las Vegas Speedway inside track, where the banked superspeedway track is part of the inside course, is one track on the west coast where you can top out.

The RE040s are also W-rated, which means that they are good for 168 mph. Do you actually think Nissan would put 130 mph limited tires on a car that can go 150+ mph? The track model that comes with S0-3s are Y-rated and are capable of 186 mph.

At least use correct grammar if you intend to give out false imformation.

 

Just some irony for you...The track model uses the same tires as the rest: the RE040's; and you said "The track model that comes with S0-3s are Y-rated, which is capable of 186 mph" In that sentence the "track model" is the subject (singular) and the verb you used is "are" (plural).

Therefore you have just commited the same error you chastised another for making, hence, irony.

You could have written something like "The S0-3's that come on the track model are y-rated, and are capable of 186." Then you would have only been giving out false information.

I don't intend to be mean or anything, but I just found this a bit funny and couldn't resist pointing it out.

Also, please keep in mind that I am not chastising anyone on their grammar so if you find examples of bad grammar (of which I am sure there are many), please keep in mind that it's just because I am lame.

Thank you and have a nice day!!

-D'oh!

 

Yep! My mistake! Hahahaha. It's been a long day.

Oh yeah, and just to add something to the thread:

I can see the point of removing the speed limiter if it is set at 108, since people frequently travel slightly faster than that (not me personally, but it is conceivable that some might). And while the rev limiter is usually based on stock tire capabilities, I know that on my girlfriends Dakota the limit is set because of the poor balance and long length of the aluminum driveshaft. I've heard of quite a few people who've had problems because they removed the limiter but then had problems with driveshaft occillation and bending. Then again, those that remove the limiter are typically pretty aware of what they are getting into and know how to correct those types of problems.

On the Z however, the limit is so high that most people will never even experience it. I also don't know why it is set to that speed. We know the tires can take higher speeds, so is it possible that the plastic driveshaft is a limiting factor? I have no idea, but I would definitely want to know the reason for the limit in the first place before trying to remove it.

After all this babbling, my point is this:
There limit is there for some reason (maybe just marketing crap, but maybe something engineering related). So while I agree that it seems lame to make a high performance car and then limit its speed, I would definitely want to know more about why the limit is there before messing with it. Also, since the gains are relatively small, there really is not a large incentive to put in a significant effort to eliminate the limiter (what's a good synonym for "eliminate"?). If the limit was 110, then I would be more inclined to do something about it.

-D'oh!

 

Oh, sure, try and erase the evidence...

Luckily I was here to catch you...

We can all sleep safely tonight.

-D'oh!

 

hahahahahaha.

 

not to spread any more misinformation, the tire info was given to me by pepboys, I do not question for a second that they were wrong, they were morons.

anyway, I think the limit is a legal limit of some sort? perhaps another agreement by japan? most cars are limited at around 155, not very many are drag limited above that, tho not many cars CAN be drag limited above that.... not sure if it could come back to nissan, but perhaps its just to save their own *** if someone manages to take the car past safe limits of the design. just like the engine can probably rev to 7000 they limit it to 6600. I doubt they balanced the tires anywhere near 155mph, so that could become an issue,

 

The speed isn't governor limited by the ecu, its drag limited at 156 meaning more power = go faster, thats the way it has been on most nissan cars like the maxima and sentra. Which is great because that means through mods you can go faster then 156 without having to remove any sort of governer

 

BlueDragon,

Where have you heard that? All the information I have, including the pre-order brochure and magazine articles, state that the car is electronically limited. Where did you hear otherwise?

-D'oh!

 

the Z33 can go faster the 155 drag is not stopping it. many high performance cars are comming with relatively low speed limiters Go look at the BMW M's for example

 

jtree007--

Where did the quote, "They tried several vehicles but found that they couldn't keep up," Schoonover says. "Ultimately, what we had to do was take another Z and mount those cameras on the other Z to be able to keep up" come from???

 

It is from a interview on Tech TV on the making of the Run. It is from the director.

 

i was told that its drag limited by the dealership people, plus i drive a 00 maxima right now and its drag at 131mph and my friends sentra is 127 i beleive, so my assumption is based on the dealership knowledge and other nissan cars

 

Just remember, in most cases driving at double the speed limit is an instant reckless driving, impound of the vehicle, and a "go directly to jail" card. Do not pass go, do not collect $200, even if you did smoke the M3 that was running you.

At 70, double the speed limit is obviously 140, and you've cut into the road design's factor of safety. Something to always keep in mind when you've got no traffic and a lead foot.

 

Nissan claims a Cd. (drag coefficient) of .30 for all models except for the track which is .29 I believe that this is lower than the last Z and is lower than most of the cars on the market. That would lead me to believe that the 350Z would go faster if it wasn't electronically limited. Also why would anyone believe the dealership over the company that actually makes a product?

 

We know. We're mearly discussing top speed.

Nobody here has said they're going to topout on public roads, or break any other traffic rules.
