Hi every one ..

before some weeks i dyno my modifying maxima and i get a good HP Number ..

and i want know how can i get more HP

You Tube

any suggestion ...

 

Other than his English, I think he has the highest dyno numbers on here. I am impressed, doesn't seem like a lot of dive loss at all. OP, what mods you got in there besides the intake?

 

Is that at the wheels!!!

 

do you have any video for a maxima on dyno ?
because i search and i get only on was stock and he get 227 hp

about the modifying that on the car i cant say it because there are so many sick people want to know it and after that they will say your car not stock your car modifying your car your car ... lub lub lub

coming soon .. i will fix a headers and we will see if it good or not

 

more accurately i think he's the first person ever to figure out how to get max WHP readings from the CVT. nobody else from vendors all the way to including several Uprev tuners who specialize in Nissan/Infiniti have figured that out.

OP - what's your secret to locking the car in gear for the dyno? you do anything special? ive hit the dyno before and everytime we tried to get max WHP readings the dyno chart ended up looking ridiculous and wouldn't lock in gear. removing the ABS fuse helped a little but it still wasn't right.

 

yep ..

because the stock maxima have 290hp on the engine
maybe my car have between 310 - 330 in engine

dont tell me i am the first one .. i think there are more than 20 one who modifying the maxima and get more then me !!

but i think they want to post it .. so lets see if any one get more than 271 hp


and sorry i dont under stand u cuz my inglish not mach good
(( what's your secret to locking the car in gear for the dyno? you do anything special ))

can u more explane it

 

Maximas don't usually perform well on the dyno because of the CVT transmission. Did you have to do anything special to get your results from the dyno machine?

 

Looks like the dyno pull from a manual

 

Interesting...but doesn't our Maximas have more than 271 hp stock?

 

^ 290 is crank numbers... this is wheel hp reading...

 

Mhmm I see.

 

And as far as wheel #s go, his is pretty good.

 

+1
I want to figure this out also. have a dyno day coming up at my local tuning shop and i would love to actually be able to participate.

Maxima 35- did you keep the car in D while dynoing the car? or did you run it in DS or M? also have you removed any sensors or fuses?

 

To everyone that's asking if he did anything special, I highly doubt it. I have listened to the video numerous times and you can tell the car shifts atleast once. I want to say its on DS mode as it holds the ratio longer, but he puts it in the gear ratio he wants (you can tell in the video) then he gradually accelerate fast to where it still doesn't "downshift" on him...

*** I am tired of looking at this video and dissecting it... lmao

 

Buy Headers, 3" Y pipe, 3" single exhaust.

 

im one of the few thats been to the dyno with my Max, you have to do something special or the car starts downshifting and all kinds of fun stuff when you red-line it. this is why CVT dyno graphs look like earthquake seismographs, they can't lock it in gear. this is why most people's CVT dyno graphs also show a "max WHP" of around 200-something, because after that the dyno results go nuts and are not-repeatable. unless you can do the same pull back to back and have it overlay almost identically to the previous its irrelevant.

its possible the OP has no idea what the shop did, but they had to do something to achieve a normal dyno pull that nobody else has been able to achieve since the car doesn't lock in gear. im just waiting till the older gen Maximas see this thread, it will get interesting since Darren Surratt built his 5.7 gen with our motor and (accurately) heralded it as the only 2009+ Maxima motor that we can see actual dyno pulls/gains on since it's attached to a manual transmission.

 

I totally get what your saying, I understand dyno and dyno graphs pretty well (no expert but no dummy either) and I can't explain it just as I am sure the owner of the orange max can't either but I can tell you that in this video you can tell it shifts ratio atleast once so thats how I know they didn't lock it into any specific ratio, and you can clearly see him select a gear to gradually accelerate... To me the real question just like you stated it can he duplicate it and have a layout showing all the runs back to back or what settings is the dyno set if any...

 

I hate to be the Realist, but even if the OP knew how to do what was done, he probly couldnt explain it to us. Like for example, this reply below, I tried deciphering it.

"about the modifying that on the car i cant say it because there are so many sick people want to know it and after that they will say your car not stock your car modifying your car your car ... lub lub lub"

Not bashing on the OP, I give him props for what he accomplished.

 

now if the Uprev tune lets you re-map the shift points on the car, you could re-map it so it holds 2nd or 3rd gear, get your max WHP, then re-map it for driving conditions. that is if the Uprev allows you to re-map shift points

 

So basically special software is needed for CVT's? since they are new with how fast software is designed there should be such software before the next gen. Probably have the car while on dyno send shift points real time? or set the software to the tranny version.. etc etc. I'm just throwing this out there cause i'm more into software than cars

 

well the Uprev tune is done with special software; you have a laptop connect to your car with a USB device and it re-programs it directly from the computer. from what i understand you can raise the speed limiter, change the rpm limiter (red-line), obviously adjust a/f ratio and ignition timing, and maybe (hopefully) adjust shift points? if thats true you can just set the shift point of 3rd gear to 7500 or somethin and just dont be stupid, hold it at exactly 7200 and that should be at least similar to a manual pull in a certain gear i'm guessing. ive always been curious what my max WHP is i just gave up on trying to find it a long time ago; now im pumped again.

 

Damn that's some great numbers! I'm curious to see how he did this as well! From the looks it's just bolt ons and good tune!

 

I'm not convinced, particularly considering this is not a load bearing pull. The OP doesn't specify anything relevant regarding effective gear calculations, correction, or if/how the TCM was tricked to hold a specified ratio. Further, look at the AFR. I don't think so. What kind of dyno software is this? Never seen it before.

 

With you on that one to bad the Car, is in another Country....

 

I want to help but plz find to me some on to Translates my words and Translates yous Questions ...

what mean (( OP ))
I try to help ...

yep at the weels 271.2

I understand from your words that how i dyno it ..
you can dyno it on " d " mode but it will be not a correct number .. you should dyno is in " M " manual mode to find the correct number
you can know your hp number when the RPM 6200 on the 4th gear

NOTE :
I read before that the US gear different than Mideast gear

my first gear from 0 to 90
my second gear from 90 to 120
my third gear from 120 to 150
my forth gear from 140 to 175
my fifth gear from 175 to 220
my sixth gear from 220 to 255

NOTE2 : I cant do the 255 with Manual mode it should be D mode
I mean the i dont use the fifth and the sixth gear on manual mode When I race some one its should in D mode

you should do it in a manual to get an Exact number .. but in D mode you will get more power

as example if I get 271 HP in manual mode that mean when i race some one i will use the D mode that mean i will get more than 271 but on CVT we cant know the number on D mode .. I hope every one can understand me

the 290 in the engine
the 271 on the weels

the best way to know your correct hp use the M mode
and there are nothing to remove it

I will try to help you more

I can send for any one the full video if it will help you ?

and the car dyninig in M manual mode

about the :
- headers : am searching now and maybe i will make custom one
- Y pipe : already I have
- single exhaust : I think its not good idea

thnx bro

did any one get some one speak arabic ??

I think there are so many Arabic people study in US ??

 

Maxima35, thanks for trying to answer all of our questions. We are all very interested in the way you did your dyno for your car. You are the only person so far to perform a dyno that looks accurate. We want to know all of the details so that we can do the same thing with or cars!

If you have a full video that isn't edited together, we would love to see that! Please share it!

Also, how many times have you put your car on a dyno? Have you been able to get the same results each time, or did this good dyno with 271 hp only happen one time?

you are welcome bro i will try my best to answer yours questions ..

there is some one from KSA dyno his car on same the dyno i use it

You Tube

its same the dyno that I dyno my car and its same tuner

about the full video I will try to upload it when I back to home cuz I am in my work now

I put my maxima on dyno 4 times (( after I tuned it )) first time i get 263 hp than the tunner fix some thing he say there is a problem on my exzoust and after that I get 270 after that he try to get more and i get 271.1 and we try more but its tha max hp 271

 

The problem that you have translated the speech but the translation is clear

I understand only the first Q that mean you need a full video with out any edit .. and soon i will upload it

 

can he tune my car?!... lol.

Ghozt, what's this tune thing he speak of??

 

yes sure .. he tune it around 632٫995 us doller

 

What AFR is it? I couldn't see in the video.

 

Looks like mid 11's. Zoom in.

 

am waiting the translator ...

 

interesting. everytime we tried D, Ds, or Manual mode it would shift to the next gear automatically. when i go to do my uprev tune ill try holding it at 6200 rpms in 4th as you suggested - thanks for the tips! nice car!

 

 

try in manual batter .. he use uprev also and he every day connect with uprev tuners and he some times send the graph to uprev tuners and they answer him in next day ..

and there is some thing it will be more interesting for all and I am waiting it also , he want remove the lock that on CVT gear to get as example (( RPM 7000 OR 7500 OR 8000 )) that mean our RPM will go to red Line

so i am say the power of CVT will coming soon at leas 280HP on weel

we all wating . . .

the dyno that i was dyno my car . . . http://www.youtube.com/user/PowerMakerDyno

 

Again he is not trying to convince us, he was simply sharing... There is a language barrier that prevents US from understanding. It is possible, and most certain that in other parts if the world tuners have invested more time and money tuning the Maxima, which is evident by the limited number of parts for our vehicles, available in the states. While I envy your setup, there are plenty of different, softwares, tuners, and facilities that not restricted by the our country's different emission guidelines...that I am sure you and I both have not seen...

 

I dont understand you sorry .. if you can enplane to me more by easy word

 

i dont think anyone is questioning the limits of the software or the differences between UAE and US Maximas, it's just when you can't lock in a 1:1 ratio it makes it hard to get accurate dyno pulls. without the explanation of how it actually was accomplished i dont think anyone really will believe it without knowing how it was accomplished seeing as countless American dyno tuners/vendors have tried and can't get consistent pulls from the dyno and CVT. even Uprev has no idea, if Uprev could offer a standard tune for our Maxima they would just like the others. i just think you all are seriously underestimating the skill/resources of the American vendors/companies who have already tried this for years and come back with nothing. i just think its much more likely that something is off with the dyno pulls (although 270 is a believable number) than the OP owns the only Maxima that doesnt continously shift..
