Champion radiators are average at best and not a high performance radiator....kinda like Cold Case.......now with that said if you have average power, meaning 500-600 range then you will probably get by with average parts that are cheaper than very good parts that are needed for high horsepower setups. The higher up the power level a person goes lets one realize the inadequacies of cheaper parts......they flat won't work well.
Mines a champion with the 4 7" fans rated at 1500 cfm each, and these cool my engine easy and driving on the street and some small hits till its more tuned in. Plus mechanical water pump due to being street/strip set up.
