I wish I knew what to say and what discussing in to help you !!!!!!!!!!!!!

 

I agree with you... I believe that something( no clue to what) was done, I just feel like we shouldn't downplay the results.. Especially when the figures are reasonable and believable.... Someone knows how to ACCURATELY dyno this car, whether it be Nissan Japan, or some tuner overseas, they just need to share the info... Lol... Everyday new things are being developed. You have the first sequential tail lights some concept I thought about, but was never feasible, I wanted those custom door sills... And look... So all I am saying is... The numbers are not to the point where this is impossible...

 

Very true and I agree 100%, as I mentioned the 270 whp numbers are believable and sound good for just a few bolt-ons and tune. Just without the technical know-how to back up how it was done most people will disregard it just as they disregarded previous CVT dyno's as inaccurate. For example with my sequential tails I did something that just has never been done before; not something that was previously thought impossible. I'm sure someone with some electronics basics will replicate my tails someday, maybe soon, and I encourage people to figure things out like this. If it was just a few of us who had hit the dyno and couldn't figure it out, that's one thing. But this is countless vendors/tuners who could not figure it out who work on countless other cars (the most common comment I heard was this is the only CVT transmission they've seen that does not have a dyno mode that locks it in gear, many others do).

 

Maybe a stupid question but how is 270 hp at the wheels believable for a car putting out 290 at the crank?

Wouldn't the HP loss be expected to be a bit larger than 20hp?

I guess the real question is, just how much power does the CVT sap?
10% 20%
I believe most automatic transmissions typically lose 20-30%.

Any thoughts?

 

I see the only way we are going to resolve this if somebody goes to Bahrain, Ghozt since you make the most sense and the the most innovative go figure out how this was done... Lol

 

no when i was stock i got 227.3
after that i put bolts on + Uprv and i got this number

and i will give you other example for my frind car ... he have G37 sedan 4 doors and as we know it have 330hp on crank but on the weals it have 273hp after he put bolts on + Uprv he get 331hp that was more than crank hp

and I want to get a real number more than 290hp on weals

 

you are welcome bro i will take you from the airport to the tuner
just tell me when you will come

 

I spoke to one of my friend whos doing dynos here in dubai UAE for various cars.. a friend of mine also got his 370z dynoed in the sqme place with only a ypipe exhaust from the US and he got 290s on whp..but he gave me the same response for cvt on a maxima.. and he also told me that it might drop my numbers if we try to tune it.. well bahrain do have excelent tuners and tuned cars.. but can only decide after going to the tuner in bahrain itself..!

 

today I will upload the full video
Precisely after 18 hours from my replay

 

331hp at the wheels from bolt ons and tune on a g37? Time for me to investigate with my buddy's over at the g forums. If they have seen the it, then OP did what he said he did and we can look further into his to make ours do it. If they say not possible then there is a flaw, and its Probly in the way the Dyno read it.



Like the mustang dynos, they read super low, there some dynos that read super high.

 

I do it on dyno mite and he also

 

To be honest there is no good tuner in bahrain I tune my car and i dyno it in KSA (( Saudi Arabia )) His name Jullan

and you can connect with him on youtube page :

I hop i can help you more

 

We truely need to know his Mod List to know anything, all I know is he got a Intake-Y-pipe and a Tune, for a 44hp increase to the wheels...

maxima 35 care to share the list of parts on the car....

 

ok I will teel you :

+2 Degree
Y pipe
R2C Intake
Stillen Pully
CJX Spacers
stock muffler
remove center catless
Remove plastic piece at the entrance to the air filter ( idont know how explane it )
Reduce the size of the wheels 18 inch
Uprv Tune
6800 RPM

is that Enough to get 44hp

and soon I will fix Exhaust + headers
and I hope if there is more part i can fix it

 

Looks like the dyno goes to 6100 or so.

 

sounds very similar to my mod list just CAI instead of R2C, Y-pipe instead of removing the center cat (same thing), and Borla exhaust. btw your +2 timing advance was overwritten when you tuned, the tune includes a much larger timing advance. my dyno tune should be in a month or two (yeah i know ive been slacking for like half a year...lol) and im gonna try a few of your suggestions while there.

 

THE FULL VIDEO FOR THE ORANGE MAXIMA ON DYNO WITH OUT EDIT

http://www.youtube.com/watch?v=B4Evm...ature=youtu.be

 

Bumb? I was reading and he posted this video and all convo stopped lol. Is this continued on another thread I couldn't find?

 

Absolutely!! This post is one of the most interesting ones on this forum! Ghozt did you ever get solid dyno numbers??

 

the OP unfortunately no longer has the car, believe it was totalled.

and no, you can't get solid numbers on a dyno with our CVT because it has no dyno mode to lock in a 1:1 gear ratio (some other CVT's have this). OP was never able to explain how he produced the results, so personally i dont buy it. its not that the stated numbers are too high or anything, just that you can't dyno a car when the transmission doesn't lock in gear, the results are going to be different every pull and depending on what gear the CVT feels like being in will show either too low or too high of a result.

 

Agh well it was worth a shot. I was really interested to see you WHP after the turbo

 

pardon my ignorance but doesn't sport/manual mode lock the CVT into w/e "gear" you want?

 

no, those are electronically simulated gears and have a built-in feature to auto-shift if you red-line it for a few seconds. trust me if moving the shifter over to the left solved the problem, there wouldn't be a debate.

 

Has anyone tried a power vs mph pulls on a dynojet? It seems that if you can't lock in a certain gear, that you could do a pull from say 20mph to speed limit. That should get you a good hp curve, however tq will not be read correctly since gear ratio is constantly changing.

 

So what does average amount of hp do stock maxima's put down to the wheel?

 

It's reported at about 227.xx FWHP

 

power vs MPH is the only way to do it, it shows less power than the car is making though so you still dont get an accurate reading. this is how my car was dyno tuned before and how its being dyno tuned again. for example though, when i was last dyno tuned the dyno only read 220 whp maximum with full bolt-ons + tune which both the dyno operator and my mechanic said is lower than the car is actually putting out. a VQ35 350z with full bolt-ons + tune can put down around 300 whp with a different transmission, adjust for drive train loss and with the same mods and tune we're probably sitting at 260 whp. only real way to test the CVT is the track though honestly, the rest of this crap is just estimation.

 

dyno pulls are usually like $100 for 3 or somethin, you guys can hit up a local shop and try different techniques to see if you can figure it out. ive been on the dyno 3 times now (about to be 4) at 3 different shops including Hill's Garage (Frank Hill is a Nissan/Infiniti specialist ex-Nissan master tech and ex-AAM Competition technician) and unfortunately there are no tricks to dyno'ing the CVT that anyone has been able to document and repeat yet. the GTR-mechanic who is doing my FI build reached out through his network to see if anyone knew, and the best response he got was "why are you dyno'ing a CVT?" lol

 

I speak Arabic and Faris azizam!

Haha sick car man! Very nice
