If your thinking about going with cryoed products...

[DevilDawg3097]

After ordering my forged parts I started to do research on cryoed parts and coated parts. So I just went strait to the Horses mouth (MFG) and sent them an email asking if it would benefit any by cryoing there products and here is the reply:

The biggest benefit to a cryo treatment comes from the stress relieving
this process provides. Both Wiseco pistons and K1 connecting rods are
precision machined to very accurate tolerances. The problem with stress
relieving is that it relaxes the part and it can change shape and some
of the dimensions will no longer be correct. I know there are a lot of
people out there that will tell you otherwise but I have talked with
several very good professional metallurgists who have told me that no
one can provide any data that proves there is a benefit to this process.
I also used to work for a different company who makes connecting rods.
We used to cryo all of the rods but could never see where it did any
good. We finally stopped doing this process and there was not any
detrimental effect but I guess you might run faster because your wallet
will be lighter.

The bottom line is I would recommend that you run the parts as is and go
have fun.

Just thought Id share and you talk about response damn 20 mins I had a reply.

I know that several here had broke spyder gears at the track...they cryoed the repalcements and never broke again..:dontknow:

:marchmellow: This was just about rods and pistons the tolerance on the spider gears are not as tight as a piston or the rod end to the crank. Cryoed gears have already been proven by the 4X4 guys but there is no data on benefits for pistons or rods. Thats what I am tryin to relay

I think idea is for close fitting metal products, like pistons, it may change the clearances from set values. Now with spyder gears or larger parts with not so tight clearances, it may be a good option.

I too have a set of cryo'd gears sitting in my garage (thanks to NBT).

Reading about Cryo'ing, but far from an expert, that it makes it more of a refined and uniformed structure. Thus hardened. I believe it is an art and a science at the same time. Getting it below a certain temperature but at the correct rate, time and recovery.

only studying ive done on it has been with rifle barrels. supposedly lines up the molecules and makes the gun shoot tighter groups.

good research, I personally do not see the value for the money on this process... at least when it comes to street cars....planes, f1 cars, etc thats a diff story..

About the only thing I would have cryoe would be a set of roller rockers

Tom is an awesome guy, he actually owns K1 and was the original designner of the oliver rods.

i spoke with him today ordering a couple sets of rods

 

[Prof]

Oliver Rods Rock!

yessir, Ed is an awesome person to deal with, between him and Tom they have been very very helpful:rock:

Then that would be the best customer service I have ever had. psst where those mine?

Cryogenic Tempering -
Completing the Heat Treat Process...

Researchers have found that the effects of shallow cryogenic tempering (-110°F) is minimal unless it is performed as part of the initial heat treat cycle. Heat treating is what gives steel its hardness as well as its toughness, wear resistance and ductility. Even performed properly, heat treating cannot remove all of the retained austenite (large, unstable particles of carbon carbide) from a steel. Proper heat treating is a key part in increasing a parts toughness, durability, wear resistance, strength and Rockwell hardness.
The beneficial changes that occur as a result of the heat treat process do not actually take place during the heating, but, rather from the cooling or "quenching" from the high temperature. (The benefits of the quench do not stop at room temperature, as many alloys will continue to show significant improvements as the quench temperature nears absolute zero.) While it is impossible to actually achieve -459.67°F, (a molecular zero movement state that eliminates all stress), deep cryogenic tempering temperatures are very efficient and cost effective in increasing dimensional stability, increasing wear resistance and performance of most alloys.

Here is the link also.

Negative 459 degrees F is also referred to as Zero degrees Kelvin.

I once started a company that we called "Minus 1 Kelvin"...we did the impossible.

 

[avmech]

had to cryo my diffs in my evo due to alot of excess power. lasted alot longer then stock. only problem is when they do let go they cause alot more damage.

 

[supercar1of1]

Great on brake rotors also!

So can we call you Kelvin?

That's cold man!
