Im looking for a SoCal company who cryos auto parts. I want to get my cam/lifters cryo'd.
Anyone know of one?

Theres no real evidence that cryogenic treatment of metal parts does anything beneficial. There is plenty of "data" that supports their claims, but when standing up against real science, it doesnt really hold up. Its more snake oil than anything, and a nice black hole for people's money. Especially when it comes to cams, you're wasting your time. You need abrasion resistance. Theres alot of work that goes into giving cams and lifters the correct temper and hardness. You temper a little too far, and the metal will not be nearly as abrasion resistant. Go too little on the temper, and the metal will be too brittle, and you can end up cracking parts. On a flat tappet cam, if the lifters has ever so slightly a different rockwell hardness than the lobes, you will wipe out either lobes (if the lifters are too hard) or lifters (if the lobes are too hard). But Im not even sure if the cams can be hardened through a heating process and oil/water or air quench, or if it can only be done through case hardening. Havent looked into what type of metal is used. There are internal engine coatings nowadays that are pretty incredible, and can be done for a reasonable price. If I were you, I would go down that alley. There would be no need for huge amounts of zinc and phosphorous in the oil to protect the lobes...you could coat the bases of the lifters and the lobes with whatever you want on there. Hard Chrome is an EXTREMELY hard coating..approaching the hardness of diamond there...and if both sides were coated, you could guarantee the exact same hardness and abrasion resistance on both ends. But, if any of that stuff flakes off and goes through the motor, thats bad news. Really bad news. But the bonding process pretty much guarantees that wont happen. One of my plating guys is Tech Plate in Anaheim. Ive had quite a few A2 Tool Steel pieces Ive machined, plated with hard chrome, and it eliminated all wear (I also tumbled the parts in moly after I got them back)...and these are pieces which are actuating MILLIONS of times. This isnt chrome, like the kind you put on your bumper. Its a flat looking, shade like iron, and is usually plated only microns thick. You may want to look into this. Then they also do moly based coatings, and other formulations of their own which can eliminate wear between all moving components.
Heres a decent description of Chromium based coatings.Electralloy Thin Dense Chrome, Electro-Coatings, Inc.
Heres where I get my stuff coated, and a description of the chrome plating. This would pretty much eliminate wiped lobes and lifters, even with the starburst oils.Dura-Plate is a thin dense chromium applied directly to a basis metal under rigid quality controls
 
Sounds like some pretty neat processes.

Thanks for the reply, I thought I was going to have to insult someone to get responses.
