Seeing AMS put on bolt on parts( exhaust, intake, UICP, LICP, intercooler, MBC) and NO tune. They claimed around 300-310 whp which would mathematically put an estimate of 350 to 360 to the Crank. Now reliability, AMS says the car runs well and i take their word for it that the modifications they put on will not strain the SST transmission.
Now with the tune ( which no one has done yet or someone I'm sure is testing the SST limits). Would prolly push 300-310 whp car to about a good estimate of 350 whp - give or take 10 whp, which then would yield out almost close to 400 to the crank or even more.
Frankly, ppl want 350whp to the 400 whp range with the SST tyranny and ppl will be satisfied.
We'll just have to hope and see. The UK ppl with their MR or AMS will be the first ppl to tell the full potential of the SST tyranny.

Any further developments on the discovery of the limitations on the SST?
For what its worth, this GT-R broke the tranny at 634 hp / 746 trq. You will recall that factory output is 480/430, so that is a 32% HP increase and a 73% torque increase. I'd guess it was the additional 315 ft lbs that did in the tranny.
Applying those same percentages to the SST might tell us that at 384 hp and 519 trq the SST may implode.
Has anyone seen any dyno pulls by modified SST equipped X's?

There is some safety factor built-in, but anything past the rated 347 lb-ft limit, and you can expect the clutch life to be shortened. If you go way past it, you can expect the clutches to slip. There have been a few MRs on the dyno with slipping clutches already.
It'll still hold a significant amount of power: 347 lb-ft @7k rpms = 462.5hp

Yeah im getting into an MR and am a bit worried about the lack of information on the tranny.
I am hoping that it will deal with bolt ons just fine. (as i dont see a turbo swap happening until it is paid off in full) So far it would appear that the MR can handle bolt ons and a tune just fine, which if that ends up being the case it will make one awesome Daily driver...

I think an X will hit peak torque closer to 4,000rpm, which gives us a max HP of 264. OUCH!
Even using, say, 5,000 rpm for trq peak only gives us a 330 HP limit.
So, the secret to modding an EVO X MR may be a PT67R turbo. That should give about 460hp and 325 ft-lb at 7,000rpm. BWAHAHAHHHH!!!
If all this is true, then I must conclude the SST is weaksauce!!!

Dont have any dynopulls of my X MR yet,but real world experience is that mine with 3 people inside the car is as fast as a 997 Carrera S (Which is 385horses and a lot lighter then the X).......
0-200km/h is 16 sec(without LC),stock its over 22sek......still with only catback exhaust,filterinsert and remap via ecutek software.
Car runs awesome,so much better then stock,transmission works fine,no strange shiftpoints,perfect.......

i have a evo x mr i will be doing some upgrades next week :kelford stage 2 cams with valve spring, down pipe, test pipe, air intake with piping, boost controller,fuel pump, 880cc injector, plus tune my goal is to make 360whp and 340wtq lets hope the tranny holds up. question do anyone out their have similar mods to a evo x mr and did the tranny hold up

Read the press release. They just tested the SST to its limits.

Your tranny will fail if you run that much power on it. Check out the posts on https://www.evolutionm.net/forums/mi...s-release.html

The RT discs are meant for customers who want more power than their existing discs will handle, and will handle high horsepower application with a TQ rating of 438 Ft/Lbs of TQ @200 Degrees F.
edit: the point being that the PR states nothing about the limits of the tranny - just the specs for the clutch packs they are releasing. I'm looking forward to that transmission cooling pack, though am not sure about the $2200 pricetag.
