Anybody have a 7Gen up to 350WHP yet?
I would think that the CVT has a limit that is a fine balance between the power the engine is putting out at the crank and the WEIGHT of the vehicle it has to pull with the limiting factor being the CVT.. In the Murano, a heavier vehicle than the 7th gen Max, they probably couldn't go to high on the HP because they probably ran into increased slipping (ie, the special friction lube they use hit its limit and allowed slippage) that over time would wear at the belt...ultimately leading to catastrophic CVT failure.....In the MAX, a lighter vehicle, the balance is shifted a bit to allow for more HP at the crank and thus less likelihood of slipping because not as much deadweight as the Murano to move from a dead start....however....I think that once you start bumping up the HP....the slipping in the CVT belts would probably increase.....thus leading to catastrophic CVT failure at some point.....AND....warranty denial....and the owner will get stuck with a hell of a repair bill for a new tranny....just my $0.02...
Here is an interesting question I hope someone can answer ( lightonthehill, maxloveraz just to put you two on the spot). With this CVT transmission one problem they were having in the past was the amount of HP and torque it was able to handle without breaking. 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?
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 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...

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!

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

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.
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.

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?
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.
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.

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...
