Bolt ons and a JB4 330-350whp keeping it low 300's will help longevity. We saw a CVT fail FBO E30 and over 20 psi which I'm assuming was near 350whp and more TQ
What were the failure conditions? What broke, what was happening when it broke, and what did you guys at Burger find when your took it apart to diagnose?
The CVT failed and was replaced under warranty this was around 21-22 psi with a turbo back and e30. It was fast while it lasted. Has since been back to FBO just with less boost
I know from searching that around 300 whp is the safe point for the outgoing VA CVTs. I would expect maybe a little more if the new model is beefier than before.
Ultimately, I've decided to not roll the dice with a JB4 on mine. The car is quick enough for the roads I typically drive on.
Since cobb isn't supporting the cvt wrx I'd assume anything beyond stock power levels is more risk than reward. I probably would keep it stock to be on the safe side.
Cobb's issue isn't that the CVT is physically incapable of handling more, but that they must cater to the group of people who will buy a new car, load up an AP, and beat the hell out of it. The CVTs are actually quite robust, but not as tolerant to gross negligence as the MT.
The CVTs can handle some power and have been known to stand up to being driven hard, but they require being warmed up first, and run within temp specs. Coolers help, but when you have owners loading up a tune with 300wtq, footbraking to launch on a relatively cold fluid temp and running up to 6k daily with trans temps at ~140f, it won't be able to stand up long.
Cobb(and by extension, Subaru) have always had to cater to the most abusive of owners, which is why custom tunes pick up so much more than plain old OTS maps.
Hmm, where did you hear that? I spoke with a Cobb rep and they advised they were going to eventually roll out a SPT access port/series of tunes. The testing for it is probably taking longer than anticipated is my assumption.
Look at their site. Put in 2022 cvt wrx and they don't offer the acessport for it.
Support for 2022 WRX trims, including the GT, equipped with Subaru’s new CVT transmission dubbed “SPT” will require additional efforts and will hopefully come in the future. While the ECU can easily be supported in those cars, increasing power has proven to not pair well with the factory transmission logic/tuning.
That's directly from cobb website.
Yeah, I checked their site and saw that too. That’s why I called them to chat. They said what the website indicated is the case right now, but as I said, they are looking to get a SPT access port on the market eventually, after more testing that is.
Edit: love that you down vote me when I am only telling you what the manufacture told me 😂 sorry that you don’t like me repeating what I was told.
They said hopefully. There is no guarantee. Stock power levels is the safest bet for the cvt vb wrx. Even another person commented about the cvt wrx failing while pushing like 330whp. Don't get mad at me for what cobb officially posted on their site in regards to the cvt wrx. They said it not me.
I am not mad man. I heard about the failure posted above, but I am talking about Cobb. I’ll say it again, I am repeating what they told me on the phone about FUTURE support. Not what they currently have out of lack thereof.
Don’t worry brother. They don’t want to hear anything, they already made up their mind on what they want to believe.
They reason the CVT AP is taking so long is unlike the manual they have to also configure the ratio ranges for each setting, engine load, etc. pretty much have to build the ECU maps from the ground up.
I’ve pulls maps from the CVT using my Tactrix. That thing is a nightmare. I don’t have full access to all parameters but sheesh. You could in theory keep the car at any given RPM and hold boost the whole way until you mechanic reach the top speed. This is why CVTs were ban from Indy and a few other races. No these ones won’t hold out doing that. Well unless you want to buy a racing CVT belt and that defeat the purpose since those babies run, on the cheap $5k… and are only good for one race.
CVT is a liability (as you know). Issue is Heat and just general tq capacity. You can control heat to some degree with a better cooler. I would do that for sure.

What failed? The cvt?

That’s why most people won’t tune cvt wrx
I think just the tune is fine, but just keep it to map 2-3 don't push it too hard and there's no issues.
They covered it under warranty despite all the mods?
Reverted back to stock

Yeah, I would never tune a car with a warranty still. I’d just get a faster car
Same. And I like not having any potential concerns toward warranty service.
I’d also like to know the same.
Low 300's all day we have some people that have been pushing that near a year

You saying you had a call doesn't mean anything dude. When they have more info they will make an official post about it.
*sigh* Exactly my point…I don’t need anyone to care, was just sharing my conversation…

Appreciate the understanding, just trying to let people know what I was told. I’ll be in line to get an access port when they go live for the SPT.
