I would think it depends entirely on the failure mode you assume or are concerned about.

I've never looked much into it, but my understanding was that cryo treating improves performance primarily by hardening the surface, which would imply better wear characteristics.

 

wait a minute... WPC ... you mean shot peening? If I am not mistaken that is what you are describing, correct me if I am wrong.

Sounds great tho, however shot peening seems to be a waste of time IMO, cryo seems to be better. However this is all "theoretical"

I would love for an un-biased shop or someone with un-biased experience come in here and explain and give their knowledge to us.

 

I haven't seen this application being used in high end vehicles, the newest technology i've seen is in the GTR and plasma coating the block.

I wonder why porsche, nissan, ferrari, lamborgini, etc hasn't used this in a production vehicle.

You'd think they would want to have the best of the best in thier motors so they can sell a car for 100K+

Just asking the question

 

I would imagine an OEM would just leave a little more metal in an area that needed more strength. Cryotreating each block would take a lot of effort. Cryotreating would only be useful if you're trying to improve what you have to strengthen it beyond the engineers intentions.

 

I agree with you and am asking the same question.

 

Similar to how shot-peening is performed, but not exactly large (in comparison) metal balls and at a MUCH higher rate of speed.

"Due to the small low mass
projectiles and high impact velocities, WPC
produces a higher amount of compressive
stress and an increase in the degree of grain
refinement to the base metal over
shotpeening. The velocities are so high that
in addition to shotpeening like grain
refinement via cold working, there is also a
melting and quenching phenomena going on
at a very micro level as well. The result is an
extremely fine grained, slip plane less nano
crystalline structure with a high degree of
surface hardness formed over the surface of
the part, unlike shotpeening which has only a
slight effect on surface hardness and
strength. Because of this ultra fine grained
surface, WPC has superior fatigue strength
gains and stress corrosion fracture
resistance to shotpeening. Due to the small
mass of the media, the affected zone of WPC
treatment is less than 0.001", much shallower
than shotpeening."----Mike Kojima

So, its a bit more than just shot-peening. Cryo used to be the holy grail for me as well, but I've since kept up with technology and I stumbled upon this... You stand corrected, my friend.

Hard for me NOT to be biased on this one, though. I've researched them both and I can't see how cryo treatment (hardening) can beat WPC (hardening and friction reduction), unless we were talking about brake rotors....... Some people are just set in their old ways, I guess.


As for Porsche, Nissan, Ferrari, Lamborgini, etc: I guess it would come down to how much they would really want to out source compared to what they are capable of achieving under their own roof with their engineers... Paying somebody else to treat your engine internals is not the best way to make the most profit.



Simple answer: If teams in JGTC, MotoGP, WRC, Pro Stock drag
racing, IRL, ALMS and NASCAR feel it can meet their demands.......I'm sure it could work for your goals, as well.

(Man, that was a lengthy post!)

 

^ hahah interesting. I wonder if you can cryotreat and WPC.

 

I think you may be on to something here...!

 

If you are in California you can find a lot of shops that will be happy to show you their facilities and show you how cryogeincs works. There is TONS of info on the web about it and you can see how it works. Go talk to someone face to face instead of reading stuff from other people that don't anything more about it than you do.

Cryogenics works every form of racing has used it and no one needs to sell you on it. It sells itself.

 

Im saying I want tests and evidence, just as I would want solid dyno numbers before I would get cams or a header. I wouldnt get a header just because Spoon told me it "works".

I have done alot of reading up, im still have no expertiese in the area, but from what I have read and learned, it sounds very good in theory. I just want tests and results to prove the theory.
