What are your peoples thoughts on doing cryongenics on parts that needs to be cryogeniced, like engine parts, and especially are our transmissions. I was thinking it would be nice, but im questioning about the pricing to cryogenic our parts, it would probably double or tripple the price of what the part is worth.

Here is a website of a particular place that does that type of process near my area. http://www.metal-wear.com/

 

I had some experience with this in grad school. Even on paper, it sounded like a half-baked idea to me and my professors, but we had one guy who was absolutely convinced. So we sent a few parts out to get treated. In practice, we didn't find any statistically significant advantages. The place that did the work showed us a bunch of fancy graphs of treated vs. untreated, but we weren't able to replicate any of their data--not even close.

 

I was told by the shop who built my modified 5th gen transmission that cryo treating does much more to increase the wear resistance of the parts rather than the strength and resistance to breakage of them. They said the strength increase is fairly negligable. I had them cryo treat the parts anyways because I figured if I broke the transmission and HADN'T done everything possible to make it stronger I'd be mad at myself for not doing so. They told me they didn't think it would make any difference and advised me not to bother and to save the money (cost $175 to have all the gears cryo treated).

 

what about on brakes, isnt that where most people would want it anyway, i have them and noticed a difference. ive read its better for heat disapation and such,

 

how about that Cry02 cryogenic intake system? anyone have any experience with that???

 

This has nothing to do with the original subject. Do not hijack threads.

 

So what exactly does it do ... Is it similar to heat treating (changing atom configuration i.e crystal structure).

One would think it would make things more dense(close packing of atoms due to extreme low temps)

Stehpen Max loves these thread

 

cryo treating supposedly gets the stresses in the metal gone by realigning the crystalline structure of the iron in the parts.

IMO it's a bunch of hooey. paid a bunch of money a few years back to cryo a set of rotors and saw ZERO improvement in life. they still cracked ~6 months later. stupid Nissan Made in China crap.

 

Matt,
Back in engineering school (marine engineering specifically) we did some studies on cryogenically treating certain components of large marine diesel engines (those massive 16-20cylinder diesels that propel oil tankers and cargo ships), and found that the relatively few components of this type had only a SMALL increase in strength/reliability vs. non-treated components - and that the increase was not even close to being cost-effective in light of the considerable additional cost of the parts treated. From a cost-benefit standpoint, it was a big-time money-loser and (as I recall) MAN B&W's diesel division (or was it Sulzer? ) took some huge hits in their bottom line because they tried (unsuccessfully) to market these parts...

My vote would be for a no-go on this project - especially considering the limited market you'd have for them.
