And that's awesome, but do you really think subaru rated those trannys at those hp/tq levels? I doubt it. Like i've said before, just because a transmission is rated at a certain # does not mean that's its limited to that. I'm sure engineers give them a conservative number. And yes you'll need LSD's to apply the power correctly, how can you argue that?

 

Yes i know. Personally i'm not expecting anymore then 310-320whp when all factors of this engine are maxed.

 

Do you really think Mitsubishi (or rather Getrag) has rated the TC-SST at high numbers? If we use basic logic, Subaru had to reinforce the transmission in the WRX given that the power was increased. Seeing as how people are already reporting overheating problems in the MR and the GTR has turned out to be the car that **** the bed, I wouldn't put much faith in the TC-SST being a tuner's dream.
An LSD is only needed if the power is so high that it exceeds the tire's ability to put down the power alone (ie. you get wheel spin). Even then, an LSD is more for handling (it reduces wheel spin in a corner). On an AWD car, you'd need a lot of power for this to be an issue. I have yet to see or hear of an 08 or 09 WRX having traction problems.

 

I doubt you'll see that with the stock turbo unless you get it dynoed on a very nice dyno.

 

NO ONE KNOWS YET. The transmission is so new that no one wants to push the limits to really see when it'll break. And just because your buddies all have over 400+whp and tq does NOT mean they push their cars. I can't see any subaru transmission being able to take double its stock limit, besides maybe the STi 6-speed.

And you'd be surprised how little power is needed to break traction, even on an AWD system. Thus LSD's should be standard. I stand by my statement when i say the WRX will be limited in its tracking abilities due to the absence of LSD's.

 

Getrag designed the transmission, I'm pretty sure they'd know what it's capable of.
The people I know with 400 HP track race their cars.
LSDs don't actually help that much in slippery conditions. I have an LSD and I can tell you, it can promote a slide just as much as it reduces wheel slip. There is a reason why an LSD is a necessity for drifting.

 

That is why I provided both systems here.
Certain Ferraris use the TC-SST.
The others use the Automated Manual Gearbox.
The chart I am showing is from a school that teach students how to build these transmissions. And they were providing examples of high performance cars that are using them.
This is THEIR chart, i am referencing to.
And I am not calling you narrow-minded and i didn't want to come off as i was saying that to you directly. But the fact, that no-one here really the authority to write off the TC-SST.
I am saying that the TC-SST is rumored to supercede the AMG which has been used for years. It has been stated that TC-SST is much better, faster and more durable then the AMG systems.

Dboz brought up the debate about how ALL (he used this word -ALL) top performance cars are RWD and AWD and they are ALL manuals. That is the only reason why i brought this up.

Which I replied, that is not true. Not ALL but most.

Lets make sure for those who are would-be buyers for the R/A, the MR which utilizes these trannies that their fears and stories are isolated and not common situations.
Their fears of a TC-SST is unfounded.

 

I hope they have a fat wallet because 400wtq and hp on any of subaru's stock 5 speeds is playing with fire.

 

And I'm sure 400 whp on a TC-SST will be as well.

 

My main problem is with this statement. As the GTR has proven, the TC-SST isn't bulletproof even when it's designed for a 500 HP car. The technology simply isn't there yet.

 

True, but the same can be said of every single computer-controlled technology, and any Mitsubishi vehicle is chock full of such controls.

I think it's fairly likely that the future is some sort of dry-plate twin clutch, certainly not the TC-SST, but not something entirely different from it. At least that's the future I see for gas-only power vehicles, everything else over the next few decades is almost certainly destined to have CVT/electric-type transmissions, as the world slowly goes almost exclusively gas-hybrid/electric.

 

No car is bulletproof.
No engine is perfect.
you said that yourself.
And for the fastest car in the world that is using a TC-SST from GETRAG, which we know is the same company that designed the one for the X MR should speak out enough.
And even if it's designed for a 500hp car or whether it be a 1001hp car.
The point is, it has been built. The point is, it is out there on the roads.
Why build a car if it's destined to be a failure?
Why build a $1,500,000 car just to only have the consumer turn it back in and call it a lemon?
And despite TC-SST transmissions having engine issues in how many cars?
20? 30? Enough for a recall?
or just 1 or 2 on a car that is using 4 turbos with a GETRAG TC-SST?
Sounds pretty damn strong if such a similar set up can handle 1001hp and 922lbs tq at 2500rpms.
kinda puts things in perspective.
So when you measure a 500hp car vs a 1001hp car on it's durability and we are talking about it isn't bullet proof?

Then what engine is bulletproof?

IMO, I believe that Getrag designed a pretty damn good transmission and I am glad to hear that it works brilliantly despite the issues.
to me that is a great turnout.

 

True but in the past the computer has generally controlled things for which human input is either A. completely unnecessary or B. impossible. In something like a transmission though, a human input is in some ways superior to a computers, at least at the moment. A big problem comes in terms of analyzing a situation and figuring out what mode of action is appropriate. No computer can do this as well as a human.

 

As I have said time and time again, comparing the transmission in the Bugatti to the transmission in the MR isn't appropriate. While yes Getrag designed them both, how many transmission designers are there in the world? Moreover, designing the transmission for a 1000000$+ car is far different than designing one for a 30000$ car. You don't have to worry about cutting corners or financial feasibility or mass-production, those things are relevant to a 30000$ car though.
Nissan was smart enough (or mean enough depending on your perspective) to instill a system that only allows launch control to be used when traction control is turned off. When this is done, the ECU makes a note of it and the warranty is void. That right tells me something. Why make launch control a warranty voiding event despite it being the only way to get the advertised 0-60 times?

 

WOW!! That is optimistic. So at 310-320 WHP and stay conservative at a 10% powertrain loss (my guess is more), you are hypothesizing 350 crank HP from a car that is 235 stock(115 crank hp increase)...(50% more)? Even the EVO, with its better turbo and a zchip and MBC with an aggressive tune can muster a 107whp gain. With some additional mods I saw one guy hit 335 whp. So to say you expect the RA to get there....good luck with that one.
