CSF RadiatorsGT2RS High Performance Intercooler Set

Cooling experts CSF and PWR have joined together to deliver a High-Performance Intercooler upgrade for the 991 GT2 RS which drastically reduces heat soak and lowers charge air temperatures on stock, modified, and tracked cars. CSF achieves this by using an F1 performance-grade core which dramatically improves the efficiency of the intercoolers within the same space constraint as the original intercooler: no cutting or welding is required and this upgrade is completely reversible.

PWR is a cooling supplier to Formula-1, NASCAR, WRC, and MotoGP, as we ll as the OEM supplier for hypercars including the Ford GT and Porsche 918. PWR is highly regarded in the performance cooling industry and known to be one of the world’s best cooling system manufacturers.

Design and Engineering

The OEM tube/fin core contains a single row 7mm tall flat edge tube along with a high-efficiency multi-louvered 7mm tall fin. The CSF/PWR high performance 991 GT2 RS intercooler kit contains a 2-row core featuring 3mm tall rolled tubes with turbulated inner fins manually placed inside each tube to maximize the dissipation of heat from the charge air flowing through the pressure side of the intercooler core. The ambient side 4.85mm tall multi-louvered fin is also the most efficient fin in the high-performance industry globally with performance similar to PWR’s Formula-1 grade race intercooler cores.

The rolled tube advantage of the CSF/PWR intercooler creates a rounded edge which allows airflow to travel around the tube face and into the intercooler core for maximum airflow and heat dissipation (Compared to the OEM flat face tube which scatters airflow when contacting the tube face).

On the left, a close-up of the CSF/PWR 2-row rolled tube intercooler core. It features turbulated square inner-fins manually inserted into each tube for maximum surface area contact and heat dissipation into the ambient air. This innovative and advanced design equates to the absolute best performance possible by lowering Intake Air Temperatures along with low pressure drop.

Both the OEM intercooler and the CSF/PWR upgraded performance intercooler kit are designed around 87mm thick cores with 103mm wide side channel end plates. This allows for a true plug-and-play “drop-in fit” installation that requires absolutely no modifications to install, and this upgrade does not require trimming of the expensive OEM carbon fiber air ducts.
