Short answer - Not much...
96 M6 - I've busted THREE 10 bolts - 2 DTS built units - w/ only a CAI and a LT4 Hot Cam kit on Street Tires!
That 1-2 shift (with a good clutch) is brutal!

I blew mine apart right outside the Drive way..Brand new BFG Street Tires on my Z06 Rims at the time. 
Then I put in a Auburn Pro Series with GM 3.73's, and testing out the ET Streets I ripped the Ring & Pinion apart...at 2500RPM's
I have since then installed Motive Gears, and I am running a full Drag Suspension, so I am testing how long it will last with the 402 and the 3600 Stall..

It can handle 1 less horsepower than you put to it when it blew up.... 
but really you'll never know..... generally with a 6 speed it's alot less cuz of shockloads.... put sticky tires on it and i'd say much more than 350 hp with a bit of hook will break it.... most likely the spider gears get stripped in the posi....
Auto's can take more abuse cuz you don't generally shockload the rearend. I'm talking stock auto's and certainly not a transbrake launch. one launch on a t-brake and your 10 bolt is toast.... if you plan on dragracing and making your car faster stop wasting money fixing 10 bolts and buy a 9" or a 12 bolt.... I blew up 5 10's before I figured it out.... 5 10 bolts at 500 a pop is the price of a full blown 9" with everything....

It's going to take awhile for this to catch on but it's sort've like a "half step" in between a stock rearend and an aftermarket 12/9-bolt:

Not a huge investment over the cost of an aftermarket ring & pinion.

i don't know but with my 100 shot going in mine soon i'd bet mine won't last long
but i have the 1st gear lockout on the window switch. i'll also NOT be spraying through the gears
i've heard if ya do it will go boom along with the engine.lol i'm guessin' it will be MAYBE 2 tanks and it'll be gone unless i baby the shift's. i do know that my 1-2 shift is REALLY brutal if i really drive it. my tires hook so good that i'm always scared it's gonna pop

It helps at the track, that thing can put some power down quick. I ripped the Ring and Pinion off of it
, the Carrier was fine, did exactly like it was supposed to do.
