1990 miata, turbo 1.6l with cast iron manifold, on dyno made 250, turned down to 220ish. Last night I did 2-3, 1-5th gear pulls near my house and came back popped my hood and my manifold was glowing a dark red, pretty dim couldn't even pick it up on camera or i would've taken a picture, i guess cast iron starts to glow at 8-900 degrees ferinhite. Afrs are good. Is this normal or is there something wrong with my timing?

Post a picture of your timing map.
Ensure you aren't locked at 10 degrees.
Ensure IAT ignition retard is set at a very high temperature and very low number of degrees and large steps.
Excessively retarded timing can cook a turbo. I lost two that way before I figured out what was happening.

my coated stainless long tube manifold would glow faintly at 1400°F EGT.

(ignore the small filter, that's not how it really was. you imagined it.)

My manifold never glowed red during the day, or at least u just couldnt see it, but at night she glows a faint red like yours

I will check my timing with a timing light to make sure my timing isn't set at 10 degrees, sadly i can't post my timing map because my computer took a sh** will be getting a new computer soon, but I know it's not to conservative, was tuned on the dyno

also
here is a random picture from ~6 years ago after my time traveling. NO, I will not share the technology of time travel with you because you did not do as I say and ignore the filter!
