Default Using a pyrometer

Hey guys I picked up a slightly used pyrometer.
Right now my set up is na.
But I'm trying to remeber what temperature ranges to look for na.
And then what temperature range to look for when I turbo my engine.

800-900 N/A is normally around ideal.
Any more than 1750*F on a turbo will generally kill things in extremely short order. Closer around 1200*F is cool & ideal. Around 1350-1550*F pre/post turbine will cause trouble.

That's how I remember it.

Understand, that there are alot of varriables... Mounting, location, engine, etc.

EGTs are hard to explain. Ive dont quite a bit of research and Im still learning. EGTs are useful for tuning but coupled with a dyno and ran to each cyl. work best. I will tell you this tho, Ive ran 1650 deg+ pre turbo on my turbo B20 for over a year now, and nothing has ever melted.
