has any one here heard of cryofreezing engin parts to make them stronger? if so how well does it work? and what is the physics behind the idea?

i don't remember the details. VWTrends had some info on it during jake's Forthcomings build. check through 2002 mags or go to jake's site (http://www.aircooledtechnology.com) or his forum on this site.

Cryo treatment has proven to work very well. Check out the companies that perform the service and read their web sites. Parts are placed in a computerized machine that regulates how fast the temp drops, how long it holds and how fast it rises back to room temp. This time regulation is critical to correct treatment. I hear there are a couple of places that just put your parts in an ice chest, flood it with liquid nitrogen and come back later.... not good- use only a reputable company. Different alloys require different timing, if the vendor does not know this, find a new vendor.

I have used OneCryo in WA state. I did my cam/lifters/cylinders.

It works best on ferous metals but other metals also benifit from the treatment. I recall Jake saying that aluminum heads run cooler after treatment.

that is because you would need to go through jake for his services. i believe he is using someone in GA though. i do not know of any names off the top of my head. i will see if i can dig something up. if you do find something on your own, please post here so i can make sure those links make it onto the VKG links page.

Just go to www.google.com and type in "cryogenic treatment of auto parts". You will get several links to compainies that offer the service.

I know of a company called Diversified Cryogenics that makes a product called "Frozen Rotors" that's popular in SCCA ProRally, and ClubRally, where brakes catch hell all the time. They may be able to treat engine parts as well.

Sorry, I don't have any contact info right now. I'll talk to my rally buddy and see how to get in touch.
