ran across this yesterday and did a little research,most of the big engine builders do it on high revving engines and also drive components like brake rotors,drive shaft yokes,splined shafts etc. Would this not work to solve 'soft' cams etc.? there is a video showing them doing blocks ,cams, cranks,and all kinds of stuff.Has anyone tried this? I also spoke with one of my high end engine guys and he says instead of this for 1/2 the cost he does this thing called 'spray coat' that he puts on everything that moves and after bakeing it in he says its better than teflon coating by far.He also ceramic coats piston tops but since we don't run nitrous or race fuel thats not needed.Really interested in this Cryo stuff chime in if you know anything about it....
