Overheat temp

[AESamaan]

I am trying to design some components for an M20 head. (brackets, intake parts, etc) Current 3D print technology has poly that can withstand some pretty high temperatures.

I know an M20 has an operating temp of 180F. From what I understand, the red line represents somewhere around 270F, and at that point you are in trouble with at least some components.

At what temp of an overheat do components like a head gasket fail? I am trying to use that as a temp to shoot for, so my components dont end up a melted gob of stuff in a worst-case scenario.

Why 3D print? Cause it is a lot cheaper and easier to use.

The temps for an affordable 3D print item are 350F. I am wondering if that is enough, where an engine that reaches that is shot anyway.

you'll have to be more specific as to the parts you want to make and where they are located but 350 seems plenty enough unless its in direct line of the exhaust manifold and reasonably close to it. On the cold side of the engine it will never see that high id say 250 would be a pretty rare event

Yes, agree with that. I am thinking all intake and timing belt cover side. Maybe the very top of the valve cover to mount some coils.
