I heard it was possible to send my block, head and such to some place to get frozen, and I'm also told it will make the metal stronger? Does anyone have any real information on this and if it is for real can I do it my self?

 

Cryo / cryro treating. Very expensive but sooo worth it!! A racing secret kept silent for years. Send your entire lower end in, block, crank, rods, pistons.

What they do is freeze the block to 300 below farinhite. The metal shrinks so much it force's and air or voids out of the metal. Making it much stronger than shot peened or even pure metals.

Engine will run much cooler. Very highly sugjested in my book!!

I will see if I can find the web site again for it.

 

Take it to these guys AWSOME work

Anyone have first hand experience with this stuff? maybe even dyno or tell me about a turbo setup running 5 bagillion psi? I am serious about it. this is something I want bad while my engine is apart. so I don't know if I should blance it before or after the freeze.

 

You should blueprint and balance your stuffs after it's treated since the cryo process will alter its shapes.

 

ive heard it does wonders for thing ....i read a site not a store site but a guy who cryoed his baer rotors and they ended up crack on him (lots of track use) but this was after 30k miles or somthing.....replaced one and didnt re treat them and they cracked twice as bad and only 3 or 4 thousand miles.......the guyy swears by them

 

its really works

 

i learn something new everyday

 

Fox 297, you have a full pick of your avatar?

 

interesting... guess I'll have to send some stuff in and see what happens...

 

Does anyone know a price range to free a block?

the site Max_CFM posted has prices.. not too bad either

interesting thought of the day:
would freexing a block-compete with sleeves make the sleeves stronger as well? If so... Is this the answer the B20 kids have been waiting for?

 

problem with freezing a block that's already sleeved is it changes the tolerances...especially if the sleeves are pressure fit

 

hmmm... interesting. So the question would be if it is possible to leave the sleeves in and freeze it. If the tolerances are going to be changed- Then how far off would they be? Could a person get it back into spec?

 

if they're pressure fit I imagine the sleeves could fall through (drop).

Places like JG claim .0001" tolerances...I'd get the pieces done individually and then put the motor together.

 

The only problem with machining parts after a cryo treating that I can see, is that machining creates heat, with heat comes recrystalization of the steel. You have to realise that any heating of these parts will change the molecular structure. I'm not saying that cryo doesn't work, I have heard great things about this process, but it just doesn't make much sense to me.
