The original Behr Cooler was designed back in the 1960s and definitely shows its age at this point. Original coolers can be ultrasonically cleaned and refurbished but there is a good chance they will start leaking after cleaning. The cleaning process may cause the coolers to fail due to its old and brittle materials, or it can remove corrosion and debris that has kept the original from showing the leak beforehand. However, the core is not the only source of leaks. The OEM cast base plate that mounts to the block can become slightly warped or aging porosity can cause the seals to not seat correctly and leak.

Issues with New OE Porsche Classic Coolers

The old original coolers aren't the only issue though. CSF has gotten many first hand reports of brand new OE coolers from Porsche's revamped "Porsche Classic" Catalog leaking within a few months of installation. Apparently the new items available from Porsche are not built as well as the original Behr coolers. CSF has now brought to market a modern OEM+ solution to this vintage design.

Development with Porsche Experts

For development of the 911/930 Engine Oil Cooler, CSF teamed up with the leading Porsche engine building experts at SV Auto. Their deep knowledge of classic Porsche engines and expertise in restoration gave CSF invaluable insight into how to best approach the design and construction. Long time R&D Partner and CSF Dealer Brian Day at Euro Parts West was also a critical partner in the development of the oil cooler design.

Research, Fitment and Engineering

CSF's goal for the 911/930 Oil Cooler was to recreate the original cooler with a modern interpretation of the design while improving functionality and reliability. To accomplish this, CSF spent countless hours in research and development. Brain Day was instrumental in really helping CSF engineers understand the 911's oil cooling system. These details and deep understanding allowed for proper engineering and creating a cooler that could fit such a wide variety of models. Improving upon a design starts with understanding the system as a whole.

Key testing and design work included:

Analyzing every detail from core strength to oil flow restrictions
3D scanning of 911/930 engine blocks and OE coolers to ensure optimal fitment
Fitting and testing on several 911/930 engines at SV Auto to provide accurate performance metrics

Modern Core and Burst Pressure Improvements

The CSF units utilize a modern and robust tube and fin core specifically designed for this cooler. This new core has higher flow, less pressure drop, and is more durable than the original design. In addition to the upgraded core, CSF added support and strength bars between the tubes. These bars increase the burst pressure which has been tested to 290 psi without leaking. The high performance core uses 7 cooling tubes with 8 rows of fins. Between the ultra efficient fin design and high flow tubes, the CSF cooler is approximately 10 percent more efficient than a brand new OE unit and up to 25 percent more efficient than a used unit.

Upgraded CNC Machined Base Plate

Because the base plate of the cooler is also a common problem area, CSF wanted to upgrade this area as much as possible. Instead of the original cast design, the CSF cooler uses a CNC machined billet aluminum plate. This offers a perfectly flat mounting surface which is both stronger and more resistant to warping over time. There is also a special helix design which adds strength while keeping weight at a minimum. The O Ring recesses are CNC milled into the billet for a perfect fit and seal. You can now confidently install your oil cooler knowing you will not get any leaks from improper O Ring seating.

Compatibility for Older and Newer Models

One of the goals of the CSF 911/930 Engine Oil Cooler was to have a single unit that could fit both older 65 to 71 and newer 72 to 89 models. The solution may seem simple, but engineering the two upgraded stainless steel fittings so there was no oil flow restriction took some extra design work.

The Widemouth fitting design:

Maintains the optimized inner diameter of the oil pipe
Offers 50 percent greater flow capacity over the OEM connection

The machined in house stainless steel fittings offer increased strength and durability over the OEM aluminum slip on tube and threaded M30 fitting. CSF also includes two high quality copper crush washers to offer the best possible seal and prevent any leaks.

OEM Look with Modern Finish

CSF understands Porsche purists want to keep an OEM look even when upgrading the performance of their 911s. This influenced many of the cosmetic features of the oil cooler including the stamped for strength X shaped design and the OE part number just below the CSF logo. In addition, the cooler comes in a Titanium color Thermal Heat Dispersion Cerakote finish. This advanced finish is durable, improves heat dissipation, is anti corrosive, and offers a classy OEM+ look. The curvature of the case matches the original precisely and includes all the fine details. The spark plug aperture aligns perfectly with the valve cover for a perfect fit. Built into the machined base plate are raised mounting pads and strengthening ridges.

Wind Tunnel Tested Performance

Extensive testing was done between the CSF Oil Cooler and OEM Oil Cooler. CSF procured a brand new old stock Behr OEM unit for benchmarking oil flow, pressure drop, and heat dissipation. Tests were conducted in the factory wind tunnel under controlled conditions. The data shows the CSF Oil Cooler outperforming the OEM unit by a substantial margin in heat dissipation and pressure drop. At equal flow rates the CSF cooler was on average 8 percent more efficient at dissipating heat and offered 6 to 8 percent less pressure drop. These results were before applying the Thermal Heat Dispersion Cerakote which further improves heat dissipation performance.
