Our four-row cores, which we call “Monster Cores,” are fairly stout and may not fit in all engine compartments. EC Economy Core Series – 2Row – Two Rows of 3/4ths inch Tubes = Approx. 400-600+ Horsepower Cooling Capacity. CC Champion Core Series- 3Row – Three Rows of 5/8ths inch Tubes = Approx. 600-800+ Horsepower Cooling Capacity. The choice between aluminum and copper radiator cores often depends on the vehicle's application and the manufacturer's preferences. Both materials offer reliable cooling performance, but the specific requirements of the vehicle may dictate which material is better suited for the radiator core. Number of Cores and Heat Dissipation Efficiency good review. i would assume the more expensive, triple pass radiators would cool better than the cheaper single pass radiators. however, unless im reading it wrong it doesnt seem to be an "apples to apples" comparison. the champion had medium profile fans but then you changed to extreme duty fans on the other 2 radiators that you said doubled the cfm. Crown Automotive Radiator for 12-18 Jeep Wrangler JK. $292.99. Northern Aluminum Radiator for 07-18 Jeep Wrangler JK with Hemi V-8 Conversion and Factory Electric Fan. $678.99. Northern High Performance Aluminum Radiator for 07-18 Jeep Wrangler JK. $700.99. CSF OE Replacement Radiator with Aluminum Tank & Core Radiator for 07-11 Jeep Wrangler JK. A 3 row radiator is not a "very inefficient design". This is a myth perpetuated by people that do not understand thermodynamics. Can a well designed 2 row radiator cool better than a poorly designed 3 row radiator? Sure. But you know what? A well designed 3 row radiator can cool better than a poorly designed 2 row radiator. Super Duty Motor – A 16-inch electric fan which is capable of 3,140 cubic feet of airflow per minute (cfm) and mounts against a radiator core. It is the highest-rated CFM fan available from manufacturer. It requires a high-amp alternator and Be Cool’s 40-amp waterproof relay to produce at peak performance. We have found that the 'red' coolants, such as Dex-Cool and Toyota's Long-Life coolant, can clog our radiators, as well as promote leaks. We recommend the traditional 'green/yellow' coolant from most name-brand manufacturers, and to mix that coolant with distilled water at a 50/50 ratio. Most any of the red/orange/pink coolants, and some of the There is much debate over whether a copper or an aluminum radiator will cool better. There are pros and cons to each material. It has been scientifically proven that copper actually transfers heat better than aluminum. But it's more of an personal preference. Why do aluminum radiators cool better than copper units? Copper has better thermal conductive properties than aluminum and that is why many people ask this question. The fact is, older copper radiators are made up of (4) four different materials, not just copper. ALWAYS better off with traditional copper-brass. cools better and lasts longer. although efforts can be made to stop it or slow it down, electrolysis kills aluminum rads. leave them to the pro touring guys! Its the 21st century!! Brass/copper does NOT cool better! AbM3Udl.
