I have a evo x mr with sst transmission and i want to tuned them. My question is : Does the sst transmission will be enough strong to 400 to 500 lbs/torque or we can change parts inside like manual transmission ?

A few people here have already tossed on a fair amount of bolt-ons with no issues. Tranny seems to be handling the extra hp and torque just fine. Do a search on here for user Director7 or something like that. I believe he is the furthest along with his MR.
I believe a few tuner companies are already disecting the SST tranny and coming out with stronger parts. Dont remember any names though. Lots of people here full of good info so they will chime in. So no worries on the torque. Tune away!

Hey there, I severly doubt the MR's tranny would be able to handle that amount of wtq without some sort of clutch pack.

I'm at 300wtq and have already experienced a "limp" mode where the car refuses to shift for a few seconds under heavy driving or acceleration.

limp mode isn't the transmision giving out, it's the ECU that Mitsubishi put in to "protect it". I know there is a NZ MR with more HP than D7's and they haven't had any issues. They somehow adjust the clamping force of the SST transmission to cope with the increased hp/torque.

Is that why you are selling your MR? I'd really like to know if there is a problem before Friday.

The limp mode is not the transmission. I agree with jamdread on that.

According to what I found, the 6DCT470 Transmission should be able to handle (Max. Torque Capacity 470 Nm) 350 wtq.

Is that 350 torque at the wheel or the crank? If that is at the crank thats not to good. That would be a tune and thats about it. If that is at the wheel then the SST guy should be ok, cause that would encompass all boltons and a tune.

That is what I need to know before Friday. No way am I living with stock power. I want at least 300-320 awhp.

I dont know who could answer that question. I would PM Perrin, AMS, Cobb, or Buschur surely one of those guys know wheel or crank. 350 at crank would be crying shame.

I spoke to a man from Getrag and he said the gearbox is electronically torque limited, and would require a reflash for the box itself, allthough Mitsu UK are currently testing an FQ-360 model with the SST, so they obviously can do it.

thats the 354bhp UK spec model with the sst

Yes it would be a crying shame. That would be about 275-280 AWHP :(

That is assuming a 20% loss through the AWD drivetrain and the average is 20-24% loss. Worst case is 266 at whp. This will not do AT ALL.

FQ 360 is a crank though

Think they are seeing 16-18 percent drive train loss on the X. It is actually making better whp than the STI even though Giving up 14 crank HP

It's torque rating is input to the gearbox - so that would be crank torque. The gearbox is not connected to the wheels - it's connected to the crank, same as a clutch.

BTW - that's a continuous torque rating. I doubt that the 5-speed manual is *rated* higher than 400 Lb-Ft in any case.

So thats 354bhp at the crank right?

Im pretty sure you are exactly right. Its rated a 400ft-lb, but stage 2 replacement is only $700 compared to the replacement of SST

Yes but you can change the clutch in the 5 speed.

Going to chat..

Yes but you can change the clutch in the 5 speed. The clutch is just the fuse before the gearbox. As you know, changing the torque capacity of the clutch does nothing to improve the torque rating of the gearbox.

And just because the gearbox is rated to say 400 Lb-Ft does NOT mean that as soon as 401 is applied that all the gears will immediately come flying apart.

True. But with the MR, at around 290-305 awtq, the little electronic limiter goes off and puts you in limp mode.

Looks like 311 awhp from what I can see. They always rate things at the crank over there.
