cryo treating?

[DonGori]

is it worth it to get the crank and rods done? anyone have experience with any parts that have been treated?

[rolling_trip]

these guys have a good bit of info on cryo treating

prob going to get my rotors done when i get them

wow not too far, thanx i didnt know about that place. I wonder what the turnaround time is.

what are u trying to do that makes u think u need cryo treating?

[DonGori]

thinking of putting the f22 crank and rods in the h22 so it gives me more stroke and compression. So i figured cryo treating it would be good insurance so that nothing breaks

A friend of mine actually ran cryo-treated cranks in his race engines for about five years, and after speaking with him one evening, he came to the conclusion that nitrided cranks gave him better wear. I understand brake rotors do very well when cryo-treated. I have feedback from a source that was using cryo-treated differential gears in a drag racing car. He broke three sets before making the decision to go back to non cryo-treated gears and his gears stopped breaking. He felt the gears were too brittle but it is possible they were not properly drawn back after the initial cryo-treatment. I think it is a good process but it does not work for everything. It's a simple matter of molecular physics. Deep freezing an existing part will not change it's characteristics. Plain & simple.It can cause the alignment of the molecules in less dense parts better align (i.e. like cast rotors for instance) and provide for longer wear ability. "Can" but not always...However it will not increase the tensile or yield strength of the part. Matter of fact it can reduce it's overall material strength which others have found out. Heat tempering or nitride hardening are far better ways to strengthen a part. Though nitride only does the outer layers.

Call procryo, they are awsome people. Someone already posted their website, but it is also in my sig.

all interesting stuff thanx for the replies, Im just exploring the best possible way to strengthen a crank and rods so all these options look interesting
