I love how this thread went from a guy with a 6.4 Hemi that needed to reprogram his fan controller to a bunch of guys with bone stock low horsepower ‘70’s engines not even running shrouds saying mechanical fans keep their cars cool.
Yeah man, if you don’t make much horsepower, you don’t need much cooling either.
No **** lol all I really wanted to know if the air flow was blocked on the freeway with the electric fan on.. update. I did add an air damn that helped level out the temp at 193 in the city.. didn’t try it on the freeway yet…
Side note.. all the guys saying to run a mechanical fan.. I can’t no provision for a mechanical fan on a gen three hemi..
Second I know your rock stock 2020 hemi challenger runs at 220. They do this for emissions. Everything gets hot and thin and spins faster. ( almost to thin) for emissions. No other reason for it! This engine is NOT stock and in a totally different car. 190-195 is my happy spot. Air flow is the current issue. The 318 in here did the same thing.. along with the slant 6. I believe air flow is not evacuating down under the car. It’s getting trapped, the whole engine bay is cylinder head and there’s not really a way for air to come through and escape is my theory. Going to get a core support to hood seal( don’t have one)
