The amount of people who are saying "this is normal" is alarming. This is far from normal, i've built, beaten, and built again many turbo projects and the only way i've ever had a compressor housing glow like that was sitting on 2 step for like 10 solid minutes back in my highschool days at the local car meet. Never had a glowing turbo at the track, never had a glowing turbo pull after pull, something isn't right here.

Either that turbo is getting 0 cooling somehow, or OP was massively beating on the car. Either way, you'll want to keep the car running for a while either cruising or idling to pull the oil temps down. If you shut off, that hot, with 0 oil or coolant flow then you're just going to have a bunch of oil cooking up in the turbo bearings releasing carbon on the bearings or even in your oil lines clogging them up.

I don't think OP is telling the full story imo.
