We need a car with a GTM kit and an owner willing to lend it to some company so that we can get brand new custom manifolds that fit the kit. Easier said than done though lol..

GTM needs this...

My thoughts on cryo treatment. On high impact parts like ring and pinions, gears. No problem. Brake rotors, the jury is still out because of the heating cycle. On something like an exhaust manifold for a turbo car. Think it might be a waste of money because of the heat cycles that it goes through. From ambient temperature to something like over 1,200 deg. (If it glows red, it's that hot) Everytime you start your car and hammer on it. It will go through that cycle. Need something like a slow warm up, and a slow cool down. Think a blanket around around the manifold will help with keeping it stable.

Coating the manifold inside and out before it cracks should help with the heat. But if you coat it after the crack starts. Thats a waste of money.

You do know the cryo treatment is not a coating right? Cryo treating is supposed to make the material 50-60% stronger regardless of heat cycles. When my car was running my logs never went above 1100F on the EGT.

Mike@GTM him self told me coating will not protect the manifold from cracking.

COSMO 02-28-2014 08:29 PM

Mike, hahahahahaha....:rofl2::rofl2::nutswinger:

does he even work there anymore?

COSMO 02-28-2014 08:35 PM

Now that wouldn't surprise me since they only seem to have very few working there. I heard sam just had brain surgery along with his other illnesses....

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.
