CSF Center High-Performance Radiator for 991 Porsche 911 Turbo, GT3 RS, & 718 Boxster Spyder, Cayman GT4 [7068]

With over five decades of radiator manufacturing expertise, CSF offers its High-Performance All-Aluminum Radiator as the ultimate cooling solution for the 911 Turbo. Designed for both street and track applications, it is ideal for high-horsepower builds and race vehicles requiring enhanced cooling performance in demanding motorsports environments. The radiator features a 2-row core with CSF’s exclusive B-Tube Technology. Unlike traditional “O” shape radiator tubes, CSF’s “B-tubes” are engineered for superior strength and efficiency. The brazed seam design allows for thinner, lighter aluminum construction with 15% greater heat transfer surface area. This innovation achieves the cooling efficiency of two smaller tubes within the same space and enables “dual liquid laminar flow” for optimal performance. CSF also incorporates ultra-efficient multi-louvered fins, precisely aligned to maximize airflow and cooling efficiency. Fin specifications are meticulously calculated and wind-tunnel tested for maximum heat rejection, ensuring unmatched performance under the most demanding conditions.

HIGH EFFICIENCY MULTI-LOUVERED FINS

• CSF incorporates ultra-efficient multi-louvered fins, precisely aligned to optimize airflow through each radiator core. Fin specifications are meticulously measured and tailored for each application, undergoing rigorous testing in CSF’s wind-tunnel lab to ensure maximum heat rejection efficiency.

CSF’S EXCLUSIVE B-TUBE TECHNOLOGY

• CSF utilizes a specially engineered “B-Tube” design instead of the conventional oval-shaped “O” type radiator tube. These “B-Tubes” are carefully crafted and brazed over the seam to ensure a secure seal. This innovative design allows CSF to employ thinner, lighter aluminum materials while achieving superior cooling efficiency, as the “B-Tubes” are stronger than traditional welded “O” shape tubes. By incorporating a seam-brazed middle section, the “B-Tube” design increases the heat transfer surface area by approximately 15% compared to standard tubes. This configuration delivers the performance of two smaller tubes within the space of one, providing enhanced “dual liquid cooling” efficiency.
