My junk runs mid to low 8s, I run a cheap summit brand one,i think it’s for a camaro or something. 3 core, mounted under the trunk floor, Taurus fan, meziere electric pump. Can cruise all day never gets over 170-180 Apples to oranges here. A new style engine w/ a turbo won't build nearly the amount of heat as the OP's engine will. I have several friends w/ GM LS powered turbo cars that are FAST and the cooling systems they use (like yours) make me jealous, lol.
