This is good info. Out of curiousity, SpeedMachine cryos OE seals. Will this process help in strengthening or extending the longevity of the seals over stock? They indicated that they were able to maintain 40lbs of boost without issue.
Claims are claims, but based on the engineering mentioned here, should I consider it fluff?

The Falken FD3S we built ran all year on one engine in the drift arena, and finally blew when it hit 46psi of boost after a wastegate nipple broke off during filming at the Fast and Furious 3 set.
It didn't blow until it hit 46psi when detonation finally won the battle. It ran over 30psi most of the season. All on stock Mazda internals that were cryo treated. We also boiled the cooling system completely dry over 6 times and had temps of 150C water, and had no housing or iron problems and the coolant seals were like new when I tore down the now destroyed engine. The whole block was treated.
I am a believer in whatever they are doing

The cryo cooling of any metal when described by a euctectoid reaction shows the same composition of metals on both sides of the equal sign. Meaning nothing happens when you cryotreat. THe only way cooling changes anything is when you control the heating of the sample and control the rate of cooling forcing the material to pass through different phase transformations.
