cryo tempered T5?
Saw some youtube video of a guy with a decently built engine in a '91, says he has stock T5 behind it that's been cryogenically treated and holds up fine. Never heard of this before so I looked around a bit and didn't find much information on cryo tempering, most of it seems to relate to engine internals, and from what I've read so far, it seems to increase the hardness of components but not the strength... so is this guy off his rocker for saying a cryo-treated T5 can hold up against 500hp?

oh, i saved this from a while back,

I've heard all sorts of things about "stronger gears" and all that, from any number of sources. Thing is, I've got a shelf full of T-5s with wasted cases, that EAT any gears I can put in them. Because it's not the GEARS that are the root cause of failure, it's THE CASE. Until you strengthen the CASE, you could put in gears forged in the fiery furnaces of Hell by 10,000-year-old gnomes from an alloy of purest virgin nonobtanium with just enough irreplacium added to make them one-of-a-kind, and the case will STILL stretch and allow those gears to misalign and they'll tear up. Frankly I wouldn't spend another dime on trying to make a T-5 survive behind some power. Oh wait.... I don't have to, I finally woke up and got a clue and swapped in something else; specifically, a T-56

that treatment is for the gears, and even with an upgraded the case, its still a crapshoot. HAs a lot to do with the clutch and traction too. You can put 1000 horsepower behind a t5 and it will survive if the clutch slips or the tires just spin.

Re: cryo tempered T5?
Neat. I'm guessing it's a bit of a trick to reinforce the case to reduce flexing, probably not worth it compared to a T56.

g force has a beefier case for only 350$ or so
