I hope Jake chimes in here.

Is Cryogenics really worth it for our engines?

I read an article stating Jake as the sole reseller of this service and he had it done to his company van,,,which in true form he went out and tried to kill the motor.
I read vlave adjustment at 15k intervals (he did check them every 1k, but no need to adjust????

Opinions and a cost estimate would be great.

I am a skeptic. Im also educated in metallurgy. None of the cryo sites offer before and after data. What is Youngs Modulus before, what is yield strength before?what is Vickers or Rockwell hardness before? what are those values after?

The hardness may change. Youngs Modulus and yield strength dont. If they did I bet every cryo site would be BOASTING about it...

like

Diversified Cryogenics

or

the one posted

They mention phase shifts from austentite to martensite.. cool talk for what happens to every ferrous metal when it cools.. aluminum...... nope doesnt happen to aluminum.

Ive used frozen rotors before. There was not any great improvent over the performance or longevity of the regular rotors..

But hey if it blows your skirt up to have cryo parts go for it.... Its your money
