hi
the CVT new transs so you should have an idea abot the car power
or cvt power so

the new max have 1 rule to get it powerfull

Accleration = how many miles your car have

that mean the car have more power as you walk as possible

so if there is race betwen 2 max

let say

first have 2000 mile
second 10000 mile

so the second will go firest

-------------------------------------------------------------

the cvt power

in my opinion

the cvt is keep engine in power line

so the cvt is faster in high speed not low

EX

acc from 0 is pad

but

acc from 60 - 80 is awesome

>>>>>>> that number by KM\h

soooo

i hope so you understand what i mean



Peace

 

I'd agree with your analysis that we lack low end power, but have decent high end. It would be nice if we could remove the WOT limiter.... I'd be interested to see what we did from a stop then.....

 

huh what

 

im guessing english isnt your first language but ill try to answer your concerns about the cvt.

But with your first question, the car with 10000 miles would probably be faster than the car with 2000 miles because the car has been broken in.

Now about the cvt....From 0 to about 20 the car has a terrible bog, but on highway speeds the cvt is great and like you said 60 to 80 is awesome

 

Red line has noticed the same thing I did. This CVT-driven Maxima is a little slow off the line, but once it gets going, it accelerates very quickly. Fantastic car for passing in short passing lanes.

 

Agree completely, but unless your drag racing people left and right, the slow off the line acceleration is not bothersome or hindrance on any of my purposes or driving abilities. I suspect that Nissan will address a couple of these minor issues and correct them with the 3rd Gen CVT in the next few years, until then, I can live with any of the CVT's little idiosyncrasies as long as it keeps yielding the *****in fuel economy I'm getting consistently !!

 

more like his 4th...

 

is the OP asking a question or making a statement?

 

He is making an observation of the way Nissan has set up this CVT so that it lags slightly off the line, but then goes like a scalded dog.

He is posting from Jeddah, a city on the Red Sea on the west coast of Saudia Arabia. All my long life, Jeddah has been famous as being the 'gateway to Mecca', the holiest shrine of Islam, which is about forty miles east of Jeddah. I have always felt that would be a fascinating area in which to spend a vacation. Various folks have inhabited that area for at least five thousand years.

Nissan Maximas in Jeddah? I guess Maximas are all over the world.

 

They drive tons of "western" cars over there, they are big into modding and racing like lots are here.!

 

give him a break, he's from Saudi Arabia...

 

I actually lived in Jeddah from 1988 to 1995. I have many fond memories of the city. It is very modern and has plenty of things to do. As for cars, some of the nicest and most exotic cars I hae ever seen in my life were in Saudi Arabia. They used have a very nice car show in Jeddah every year.

 

post some pics of your max red line

 

How can anyone state categorically that the CVT is the reason for the lag at lower speed? I haven't seen a torque curve for our 3.5, but, I have a sneaking suspecion the curve isn't too high at low RPMs

The CVT would have to slip for the CVT to cause a 'lag' off the line.

 

It isn't the CVT as such. It is the way Nissan has programmed the electronic controls for this CVT. I'm sure Nissan has reasons for doing this. It may be that they feel this CVT is most vulnerable at takeoff, and since they warranty this CVT for TEN YEARS, they are protecting it at its most vulnerable point.

 

That is 100% exactly what it is.

It isn't so much the lose in the tranny itself but the tranny creating (doesn't seem like the right word but I was blanking on a better word) the lose to increase long-term efficiency and overall safety for itself. Besides, thats what rolling starts are for .

 

I would submit that the CVT is NOT the weak link in any slow off the line acceleration.

Try turning your VDC off. From a stand-still. Stomp the gas pedal down. You'll lay a bit of rubber as your tires search for traction. What more can you ask for? If your tires can't lay down the power, it doesn't matter what the CVT or engine do.

 

'A bit' of rubber isn't enough for maximum acceleration, and I personally don't get more than a chirp regardless of the VDC position. Better tires would make for an even higher threshold. There's definitely speed left on the table.

 

yeah that what i want by this subject sharing idea so

you ask me to but some pics of my ride i will do it soon >>> its stock

so for accleration from 0 - *** i have an opinion so i will try it on my friend max

so the project is

short CIA

Short headers

Exuast

Stock muffler

i guess that will give an acclearation from 0

when he do it i will give you what happen

& thanks for everyone who respict me & show me some kind of mercie

Peace

 

hey Brother if any one want to come into jeddah please tell me & I will do the all hospitalitty & I will be his spiechal map

thanks alot

 

I probably won't be going to Jeddah any time soon, but we appreciate the friendly offer.

Keep posting!

Peace

 

Actually, you won't be accelerating faster by laying down more rubber.

If that were the case, then the NHRA guys would be laying down rubber for a whole quarter mile.

If you were looking for a sub six second car then you purchased the wrong one. It's difficult to lay down 290 hp with two front wheels, nevermind trying to laydown more.

 

Good luck with the modifications! Looking forward to seeing pictures.

 

i think the bog in the 0-20 is more to help prevent torque steer because think of it 290 hp on front wheels nissan must of had issues with it development and decided the bog in the beginning was appropriate. instead of other car makers who just put all these computers to limit slip it seems nissan went for the bog the engine route.

i dunno just my 2 cents

 

yub i guess that


lightonthehill you & anyone is willcome in jeddah city & the frindly offer will be until i die so iam wating for anyone

 

It's cool to hear from international Maxima owners. I see you mentioned that one of your friends drives a Maxima. Are Maximas very popular in your area?

 

Red line - Thanks for the kind offer. If I ever get to Jedda, I would love to meet you and see your Maxima.

 

I keep my '09 Maxima mostly in manual mode to overcome/bypass this 0-20 bog. As you guys know the engine struggles to work through the bog, and get up RPM to keep it comfortable. Like being on a mountain bike going uphill in 10th gear. Your legs would hurt. So is the engine being stressed during the bog?

Or am I doing harm to the tranny to keep it in this position all the time, and letting the CVT see the engine's torque? Is the bog put in intentionally by Nissan to protect the CVT at the low speed/High torque points of the engine's curve. I believe high torque is why we havent seen CVTs prior to this Maxima (or in any make or model). Nissan found a way to implement the CVT to a high torque engine. Is the bog responsible? Thanks in advance!!!!

 

This is a question for others here who have tranny/torque backgrounds. But I have seen several posts here over the last few months that tend to see this as you do - Nissan feels the CVT may be most vulnerable at takeoff, so they give it a little protection at that time, and that protection shows up in the form of a slight takeoff lag. I doubt the engine is being stressed during this lag.

 

well it looks like all of us are welcome to Jeddah should we ever be out that way. didn't think people of Islam were too fond (spelling?) of us americans. or Saudi Arabia for that matter.

 

That is an understandable misconception. Probably 95% or more Islamic people hold to the true interpretation of the Quoran, which is more along the way we interpret our Bible. There are violent passages in both, but the key is in the interpretation. But most Muslims wish only to live in peace and raise their family.

Of course that 5% of Muslims who are overly strict and literal interpretists, and vulnerable to the twisted and violent teachings of belligerants such as bin Laden, are very dangerous, and can cause us much grief.

I personally would have no more fear of travelling in most Islamic countries than going to a movie in downtown Atlanta at night.

 

brother i guess there some of misunderstanding .

here is saudi arabia is safe .

there is no gang & you will never see anyone have gun or something like this

so we live in peace but as you see there is good people & bad people soo

look at your vinger not same ..?! so i would like anyone to come & see this country

thin lets him judje by him self

so you & anyone are welcome & i will do all hospitality sinse he arrive to the airport

so

the people is no same

Peac

 

you are welcome brother but i will have to show you the tuff car & the fast car

notice >>>> all tuned part we import it from your country

Peace

 

Hi there,, am also from Saudia Arabia .. from the eastern Provence,, as my brother Red Line said here in Saudia Arabia we welcome any body to visit us and enjoy our Arabic hospitality.. as the Maximas case here,, you will be amazed.

 

Hmm I still need to get used to the CVT concept, but for the time being... 6MT FTW

 

Welcome, ali_209. You must live in Ad-Dahna, maybe east of Ar Riyad? Or near Al Hufuf?

We hope you find maxima.org to be a helpful and friendly place.

 

Found this.

Acceleration vs wheelspin is too case-specific to make absolute statements.

Tires do not follow the linear behavior predicted by what you learned in high school physics class - likely nothing about tires is truly linear. Here, they typically make best grip when they're slipping by about 10%, which you could consider to be 'incipient wheelspin'. Not quite spinning, but not truly rolling either.

If you don't have enough low rpm torque (and overall "gearing") available to avoid 'bogging' the engine, keeping the wheels spinning can result in better acceleration. You gain more by letting the engine run up where it needs to be working than you lose from sliding friction being less than rolling friction. Obviously, there are limits as to the number of situations where this technique gains you anything, and how much you gain when it does.

Cool. Thanks for the link Norm.

 

Thanks bro. correct am living in Qatef.. it is near Al Hufuf,,about 200 KM.
am sure maxima.org is the most useful site i ever seen because the gays here r experience in the MAX. am waiting for my 7th gen. max to come next week,, hopefully.
