Glowing Turbo!?

Glowing Turbo?!
I went on a drive with my friends last week through the mountains. We stop occasionally on the drive to cool down the motor and the brakes. My friend, who has a turbo car, told me to pop the hood to see if the turbo was glowing. Sure enough when we stopped and looked under the hood, the turbo was glowing. Tonight I drove home (30 min freeway drive) only going about 70mph, and when I got home wanted to see if the turbo was glowing. And again it was. I was just wondering if this is normal?

I think it's normal on a turbo car, i think it even happens to N/A cars with headers. It's made of cast iron which reacts well to the heat and cold. Should be ok though. Thought: Your ehaust manifold is also made of cast iron. It probably glows when relly hot too. That is why when you are drilling your manifold foor an EGT probe you need to go slow as not to crack the cast iron because all of the hot and cold can make it brittle.

the up pipe without a cat should reduce the heat only marginally.
As for your turbo life i wouldn't worry about it. The fans i believe are coated to pervent damage by the extreme heat. Which makes me wonder, if we coated the inside of a turbo with jet hot i wonder if it would be more effecient.
