CSF Left High-Performance Radiator for 996 / 997 Porsche 911 Turbo, GT2 [7056]

CSF Left High-Performance Radiator for 996 / 997 Porsche 911 Turbo, GT2 [7056]

With over five decades of expertise in radiator manufacturing, CSF offers its High-Performance All-Aluminum Radiator as the ultimate solution for keeping Porsche 996 and 997 engines cool and performing at their best. Designed for both street and track use, this radiator is essential for high-horsepower builds and race vehicles that demand enhanced cooling in motorsports environments. Featuring a 2-row core with CSF’s exclusive B-Tube Technology, this radiator outperforms conventional “O”-shaped tubes. The innovative “B-tube” design, carefully formed and seam-brazed, is stronger and lighter, enabling the use of thinner aluminum material for improved cooling efficiency. This design increases the heat transfer surface area by approximately 15%, offering the efficiency of two smaller tubes within the same space and enabling dual liquid laminar flow. CSF complements this advanced design with ultra-efficient, multi-louvered fins precisely aligned to maximize airflow through the core. Each fin’s specifications are meticulously measured and tested in CSF’s wind-tunnel laboratory to ensure optimal heat rejection and performance for every application.

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.
