Cryo treating

[mnoll406]

Anybody ever try cryo treating engine parts? How did it work out?

anybody ever try this? I read a little bit about it, and it seems to make the metal more uniform and dense. It actually changes how the metal looks at high magnification. It also really changes the hardness. Turbo or a magazine like that had some parts treated on one of their projects and they had to drill some part afterward and said it was almost impossible. Went through many drill bits.

I have done quite a bit of it when building performance motors.Cost is pretty high,and it's really only needed when your pushing the limits of certain parts.

There are some parts that work well when treated,other don't.

With the availbility of better performance stuff out there,most guys prefer to buy better stuff rather than try to make their stuff better.

saw a little bit on it in a trade publication at work,,theytalked toa tractor pulling dude w/a big allison,,he said,he used to tear down every season,for rebuild,,he is on his 3rd or 4th season,and not needed to rebuild it yet,,just put it back together,,,i bet its great onrings+pistons,even the block

I'd be interested in this for the rings and pistons for sure. Now do any of our local venders gonna start selling them. Just a thought James Morrison

The last time I looked into this, the places that provide the service offer pricing appropriate to the number or cylinders.  

I know a guy who cryo'ed his chevy diesel, and he's been running higher boost on it without problems.  

If the treatment creates an engine that lasts longer, I think it's worth the $500 or so.  I'll be doing it to the next engine I build, for certain.
