Cryogenic Treatment

Re: Cryogenic Treatment
I cryo tested a piston for a Pro Mod customer, he was interested in longevity and we wanted to know if it changed dimensionally. Ring grooves in particular. He then ran that piston with the untreated pistons with no appreciable difference. He didn't order any more so we did not push that process while not discouraging those who swore by it. Mondello in particular wanted to treat everything in the motor.
Re: Cryogenic Treatment
From the reference point of absolute zero, cryogenic treatment is just 'heat treating' and I see no reason why all metals should respond the same..

Re: Cryogenic Treatment
Is it possible to do a back to back test and what test would you perform?
Given we are dealing with 'durability' (I think) I guess it's a tough one hence no-one seemingly done it.

Re: Cryogenic Treatment
Maybe something along the lines of changing up one front rotor, then when the first pair is used up, put a cryo part on the other side...

Re: Cryogenic Treatment
You need to do proper lab test for wear resistance, hardness, strength, fatigue etc and then look at the microstructure to see what is going on if anything. Field testing is a long way from being conclusive as it's always quite uncontrolled
Re: Cryogenic Treatment
My apology if this was answered in the previous posts... but does aluminum show any benefits from this treatment? The company that makes the rockers I use currently offers cryo as an upgrade for them, but I've never understood where the advantage for aluminum would be? Thanks - Brad

As far as documenting improvements, I can only say that after 30+ years that block is still in one piece making 1000+ NA hp as of this spring.
Re: Cryogenic Treatment
If you put one treated rotor and one untreated on the front it would be quite a reasonable test. Wish i'd thought about it before as I've had a few done.
