I PCed some exhaust manifolds for my car. I did them in the standard cast iron grey. I measured the temp of the manifolds on the car when I drove it tonite and it was 420.
Is that enough temp to kill the PC thats on those manifolds that I want to put on the car? How hot can regular PC get and not get damaged/discolored?
Would I need high temp for other engine parts? Valve covers? intake manifold? My intake measured 193 earlier. Just a naturally aspired 350.
