CSF Universal Drag Race / Tuck Radiator w/9in Spal Fan - 10.5in H x 10in L x 3.6in W - Black

After more than 9 months of R&D, and input from some of the best import drag race builders in N. America, CSF has brought to the sport compact market the most advanced drag race cooling system ever developed. Introducing the KING Cooler. For the longest time, buying a drag-race radiator was a demanding process. End users had to custom-order the unit based on their connection and mounting specifications. Typically, this process would take 2–4 weeks and be rather expensive. CSF has eliminated this hassle by ensuring that these units are in stock at both of CSF's coastal warehouses and on the shelves of distributors and supporting dealers around the world. Universal fit allows for mounting in multiple configurations. The triple-pass flow structure allows coolant to flow across the radiator core three times before exiting, for the lowest possible outlet temperatures. This radiator features a 2-row core with CSF's exclusive B-Tube Technology: Unlike a regular oval-shaped "O"-type radiator tube, CSF uses a specially engineered tube shaped like a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal it. CSF can use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than standard welded "O"-shaped tubes. The design (with the inlet in the middle of the seam-brazed tube) increases the tubes' heat-transfer surface area by approximately 15% over regular tubes, producing the efficiency of two smaller tubes versus one large tube within the same space. With "B-tubes", you can achieve "dual-liquid laminar flow". CSF also uses ultra-efficient multilouvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat-rejection efficiency in our wind-tunnel lab.
