Yeah, it's freezing the **** out of it. LOL Lower the temp down to around -300F to stabilize the molecular structure. It's used to remove residual stresses, and improve wear resistance. The company I used to work for did it for awhile. Wasn't a money maker for them. We also did plasma spray coating for thermo parts. I feel comfortable with it on ring and pinions and gears. But for manifolds, I don't know. 1100F is still hot. It's glowing.

We do several manifolds including Greddy. You have to understand manufactures don't dig them and sell them. We have to force the metal into shape therefore creating a mountain of stress. Or send me a manifold and I can jig it up and make a better one.

Damn, willing to pick up the pieces of another company's failure. Instead of pushing their own kit, they offer to fix yours. Big respect to you guys, putting the enthusiast first.

I understand where you are coming from.

I've worked with castings and forging for along time. Know all about the stuff.
