People cryo car parts?
I'm familier with cryo freezing rifle barrels...the cryo treatment GREATLY strengthens the steel of a rifle barrel, reduces, flex, and results in incredible accuracy gains.

Keep it lubed .... keep it straight .... and keep
I know of some rotary guys that did that to their rotors and eccentric shafts. They were well above 1K hp if that tells you anything.
cryo treating has been around for a while but not really talked about, i dont know why. Cryo treatment is a proven treatment for strengthening bare, pure metal. most problems in cryo treating used engine parts, is people will get a block, crank, rods etc cryo'd but there will be impurities in the metal, and cryo treating will end up weakening the metal. search around there are alot of websites with info on it. alot of people swear by it and alot have broken parts that were treated.
Cryo strengthens the metal by tightening the metal particles. In more than most cases it is effective. I haven't heard much of it being an ineffective thing to do such as mentioned about. Ben, shaggy dave cryo'd his rotating assembly in his volvo. He'd be a good person to talk to about that. Just let me know.

I bet it's useful when you are talking about cast parts. But if the parts are forged, I don't think a cryo treatment will get the molecules any closer together IMO.

I don't like cyro-treated parts. I think it's bogus....
A certain type of metal has a specific density. There is no way in hell that by FREEZING the part, you're going to make it any more dense. It's basic chemistry, and you can argue until you're blue in the face, I'm not going to believe you.
It could be much more dense while it's down at the sub-zero temperatures they treat it at, however, when it comes back up to room temperature, there is no physically possible way that it could change density.
Hardcore has one very good thread that is probably a year old that is filled with info....

i was reading some of the arguments over on hardcore about this and an opponent of cryo'ing gave this example. he was comparing the process of freeezing to heating and stated that when you cook a hot pocket and let it cool off, that it goes back to the state of originality. that is true, but try to cook that hot pocket again and you will notice it is much more stiff and rigid. i am not expecting miracles here, just an improvement for the cost. i found a couple of places that will do a set of rods for $65, that is pretty reasonable imo. most places will charge like $2 a pound for smaller parts, a whole tranny could be as little as $200.Joes95GT said:
here is my promise to stangnet, i am going to replace my worn out/grinding t5 in my 95 with a rebuilt t5, and get my car dyno'd. i will then rebuild my worn out unit cryo'ing all parts and post before and after dyno results of both tranny's. the reason being that a cryo'd part is reported to have less friction, thus transmitting power more effeciently(less drivetrain loss).

It doesn't move the molecules closer, that would make it shrink, but it's a metal so they are basicly touching anyway. It doesn't make it denser since that would make it heavier since it doesn't shrink. All it's supposed to do is rearrange the crystaline structure. The steel is made of a face-center-cubic strucure created in the heat. Cooling it down to close to absolute zero very slowly and controlled, tends to rearrange the molecules into a different structure called Martensite. How it affects the strength of the steel and it's stress-strain behavior is outside my knowing. So I'd like to see subjective test info on it, but I doubt any of us could find it.

Plenty of results with rifle barrels...obviously, it does something which results in decreased barrel flex and increased accuracy.

That is how they get different grade bolts, but heating them up, and cooling them down in different methods.
