Magnum cooling

@Evan Dutch I wouldn’t run any engine with boost on pump gas above 170 degrees. You’ll fight detonation like crazy. 160 would be even better. If you have a 160 stat and it’s running at 200 on a 70 degree day then what you’re seeing is the top of the efficiency range of your cooling system. You need more cooling system. More air, more water, or both. Testing will help decide which is lacking.

I just don’t see a way to get it to consistently run that cool. It’s got plenty of coolant capacity. And airflow isn’t restricted, I’ve got a trans cooler and power steering cooler but I don’t feel it’s impeding airflow that much. I could add vents in the hood to draft out the hot air while cruising
