People were impressed when they first put the CVT with the power the Murano has. They steped it up and put it with our Maxima. My question is how much HP/torque can a person SAFLEY add by modding their 7th gen? Would you think you can over do the HP/torque that this transmission can safley handle without having problems? Might that be the reason they did not put their new 3.7 liter engine on the totally redesigned 7th gen because of what the tranny can handle?
2 GO B4 those were my original thoughts. I think we were on the same page with our concerns

There will always be a difference between flywheel hp and wheel hp. A manufacturer will always measure at the flywheel because they can. With their equipment, they can also also measure hp using a wheel based dyno.

Many of us wanna know how much hp this tranny can handle, I think theres really only one way to find out, Why not call up jatco the maker of the cvt transmission and ask to speak to the tech dept or something.... Can anyone post their contact info , Ill be happy enough call give them a call and see if we can get the answers we need.

Agreed it would be interesting to find out what the limits of the tranny are. However, if the types of questions being asked in the original post are any indication of his friend's level of automotive knowledge/mechanical competence, there is a 99.9% chance of dissatisfaction with the end result. (Unrealistic goal + uncertain motivation) x $$$$ = fail from the start.


I mean no harm or disrepect to anyone. Just sayin'...

I snuck into a private airport by my house and stole 5 gallons of jet fuel. I waited till my tank was bone dry to fill it up with the jet fuel. After filling up I went to the app store and downloaded the highly reliable dyno app. I ran the car after starting up my newly purchased app and reached 160 before I knew it. I looked at my results on my phone and it said I had 390 HP! That's a gain of 100! I'm not sure though if it is actual HP or WHP...I would have taken a second run but my engine blew up...

A WORD OF ADVICE Always read your insurance contract through and through. Everything would have been paid for including the rental fees but they got me in one of their "loop holes". Boy was my face red when I found it there was a "Jet Fuel Clause". I have really got to start reading the fine print! I guess it was right next to the "If you are a dumba$$ clause". Who knew?!? But none of that matters!! Did you read my first post? 390 HP according to the iPhone dyno!!! That's all that matter in the long run baby!! Or is it?

I appreciate you concern, I really do. I was only trying to make a funny with a somewhat of a hidden message. Trust me I would never do anything like that ever. Besides I bought a maxima not the Batmobile and Im am quite content with it. I might one day purchase the Ypipe and and intake but that would be the extent of it. I am currently trying to close on a house and the majority of my money is going to a down payment and upgrades around the house to make it mine. With a new morgage payment Factory warranty is more of a concern than 350whp. If I was equally concerned with HP on a sedan as the warranty it would have been the CTS-V I'd be cruisin around in. And there would be no need to dump jet fuel in that puppy!

Wow, I don't know about that one. Looks like someone could have been severly injured. I don't know the story behind the picture but I wouldn't be turning it around into a joke if it was me.

To be honest, that hit doesn't look like a horrendous impact. I have a feeling some of the stuff fell off before it got to the lot. If you note, there's something very fishy about the picture. There's a lot of stuff missing, and no damage past the front end of the car, even the glass is all there and appears in one piece. All I'm saying is it's just as likely that all parties inside walked away unharmed.

Anyway, so what about the joke, seriously. I thought it was funny, especially when it looked like someone took him seriously...

I don't see 350 happening, I lurk on z boards and guys with 350/370Z are shooting for 350 NA, and they have a car with performance mods, and a trans that can take the power increase

350 WHP is my goal too. I haven't really gotten started yet, although I did add a CAI. In the near future I am swapping out the exhaust and possibly modding the ECU, although I haven't heard of anyone else trying it so I might wait on that one. Aside from that, a turbo should boost it up to that goal, provided the CVT can handle the added power.

350 would be perfect for this car to the wheels but you can never get it without boosting, if I were you and planned to run a turbo then I'd make sure that I run it at no more than 5lbs boost to be safe with the CVT.

As far as modding the ECU then I'd probably keep the stock one in place and see if it is possible to do a piggyback set up.

Good luck with your project and car.

Thanks for the feedback, I am most likely going to do exactly that, once I have the money. How would one go about testing the WHP, cant the CVT not be effectively dyno tested? I guess just do several tests and average them out?

I doubt anyone has put Nitrous into the 7 yet or atleast I haven't heard about them yet. As far as dyno I only know of one person who has tried and I don't think he ever posted his results since the were so inconsistent.

I like the signature tribute to your past and present 02's. Are those photos the actual ones or just pics you pulled off the net?

Man, we beat a dead horse back to life and then again back to death on the issue of dynoing a CVT; someone from another forum claims to know how to do it but I forget which thread that answer is in.

I wanted to do either a single turbo set up or a tt set up but it appears that everyone is fickle regarding the durability and strength of the CVT to handle the kind of power a turbo puts on it.

Once my warranty runs out then maybe I'll either buy an SC or run nitrous, not sure yet but that won't be until way down the line sometime.

Yeah man. With the extreme uncertainty of how far we can push our CVTs the last thing on anyones mind is (or at least should be) running nitrous of forced induction. I would have loved a TT setup again but for me it is just not worth it. CVTs are not cheap.

i think i figured out how to do it..
if it was in manual shift mode it would be alot more consistent,
wouldnt a fixed 3rd gear run do the job?

Plus that was how K&N measured the horsepower increase for their CAI systems...
