hey everyone, if you have the chance to have all you shizzit cryo'd for free... would you? my buddy's dad has a 500lb tank in his garage (he works for air liquide) so it costs me nothing. this isnt a kit, this is the real thing, that costs like 400 bucks from a quality place. so any opinions?

 

its free, why are you asking...

f%&king thinking

 

Cryo treating's benefits are not so much strength, but primarily in fatique and wear resistance. So this will significantly increase the durability of your setup. Consider treating all moving parts than have metal-to-metal contact.

 

for free it's good, but keep in mind that your specs/clearances may change from it, so you might have to spend $ to have the parts properly machined back to spec. be sure to measure before you get less than that for which you pay: a heap of expensive, broken parts worth virtually nothing.

 

Just an example of how well it works. My brother works at an injection molding company and recently had a lot of the tooling for molds cryogenically frozen. The tooling used to last at maximum of a month before having to be replaced but now he's had the same tooling for over a year without a need to replace anything.

Isn't there more to it than just dumping the stuff in a vat & letting it sit? I thought the temperature was cycled on a specific schedule somehow . . . . .

Yes there is. If you just dump your material into a vat you will freeze shock the material and you will get negative effects. The trick to cryo freezing is to slowly cool down the material over a certain time frame, this will give you the desired benefits of cryo-treating material.

 

no dumping! craziness i say! in this tank, its controlled by electronic timers and whatnot. the tank itself takes 500 lbs of material in one freeze. the electronics lower the temperature (using the nitrogen) to -300 at one degree a minute from room temp, hold it there a bit, then bring it back up in the same manner- one degree a minute- to room temp again. durability is definitely a plus for me, but all i will have apart is the block. so im thinking pistons and rods (2 sets, one for the future), rings, crank, bearings, miscellaneous parts like blots and whatnot. down the road ill do my head, but for now, it is alllll brand new anyway, so when i wear it out a bit, ill do more of a build and do it then. if its free, it me, and this process doesnt change the size or fotment at all, it is on a molecular level (however, im sure ill hear if im wrong on using this term, but its the best i can do!).

 

I have worked with a local cryo facility for other reasons, but get this:

They have test results indicated that a cryo treated razor blade will last about 4 times as long as an untreated blade. This is based on colaboration with companies such as Gillette, etc. They know the benefit, but they (the razor companies) don't want to sell them, because then their products last too long then, and they want the product to remain a frequent consuming product.

 

I just read RPM's post. Werd.

 

Would it be possible (or logical) to cryo treat the block so that the sleeves would become stronger and more durable? If so, would this be a practical alternative to having the block sleeved?

Interesting line of thought.

I'd be worried about dissimilar metal expansion rates (sleeves versus block), and I dunno if the sleeves would be any stronger for it... VERY interesting question though.

 

Yeah, that's definately something that would take some planning and thought. I'm not sure how the different metals (steel and aluminum mainly) would take to contraction and expansion against eachother. Definately a cool idea though! I know the subaru guys would be jealous, i've heard of improvements by cryo treating their gears/trannys.

 

hey all, i have someone on ha.net who has some good advice. ill post a link there at the end of this, hope i dont get into trouble! hehehe, anyway, apparently i dont do things that are billet, forged, or multi-metallic, ie, the pistons, the bearings... i was advised NOT to do the block because i run the risk of the sleeves falling out, but if i were to do them separately, it might work, eh? ill be doing crank, rods, and cams, maybe something else. keep talking guys!

The best way to imagine Cryo-treating:

"Picture a busy mall with people walking around everywhere, some spots are more crowded than others. The people represent the molecules and the spaces in between them represent weekness in the metel. When the metal is slowly cooled you gather all those people and group them together as close as possible. When the metal is heated, imagine the people grouped together each taking one step outward away from each other, all of them together and in unison until they cover the mall end to end. Now all the molecules are evenly spaced, there are no weak spots, heat dissipates faster, etc. By Cryo-treating you create a more uniform molecular struture therefore creating stronger metal."
