what problem are you trying to fix by cryoing everything?
no problem at all....
again I never said I was going to or for cryo treating everything
as of right now im only for cryoing stationary gears, eccentric shaft, seals and springs.
I have a question on cryo treating the rotors though, wouldn't it make them heavier?

Cryogenics is a liquid nitrogen process. It is a metal hardening process that bonds the molecules back together. Reason being when metal is hardened and forged at atmospheric temps the molecules separate and cause austenite. When the metal is rehardend for "treatment" in controlled environments the molecules can restructure tightly pushing the austenite out that cause the metal to fatigue in these points. “Kind of like coal to a diamond”
2 things happen.
1. The metal becomes stronger
2. Heat transfer becomes greater.
The stronger metal is the more brittle it becomes. Soft metals bend, hard metal crack and shatter.
Cryogenics claim results of.
Durability (resistance to wear and fatigue) is around 100% (that’s double), the typical increase in strength is 30% to 50%

Cryo treating doesnt add mass, the only way you can add mass is to add some material to the rotors and cryo treating doesnt do that.
I am skeptical on cryo treating and its supposed benefits. But if cryo treating does in fact do what it claims then I certainly wouldnt treat the apex seals. Why would you want them to be harder? They would be more brittle than stock and they would wear your housings down faster. Seems like a

cryo treat the housing then also? lol
ask Dee why the apex seals in the fd drag car are cryo treated
