well I don't know too much about the sst in the ralli art but if it's like the mr you could run a safe 315 hp/tq being conservative. Anyone wanna elaborate on the ra sst?

I have seen a few Ralliart transmissions die prematurely after additional power. Bryan@GST is the man to ask, since he owns a Ralliart, but from what I've seen on the boards, Ralliart SSTs die 5:1 compared tot he MR tranny, and it seems it's almost always because of additional power. 20k seems to be the magical mileage number.

We know the programming is different between the two models. MR has Super Sport and Launch control and opens the waste gate before the RA to protect it from high hp. We suspect the clutches are different grades as well. Other than that, I believe they are the same.

What I am currently running with my RA SST:

It initially had issues in 1st gear only, shifting issues, which I had posted about awhile back. It has since been solved (so far) with some creative tuning.

100% stock SST trans with OEM fluid.

If I don't have ASC completely off the car will trip it every time I go WOT, even in a straight line on dry pavement.

Sorry, was going from memory. Thought it was opening the wastegate in first gear on MR and not Ralliart, but it's throttle limit.
