Product Details
The CSF R-1 Triple-Pass Ultimate Motorsports Competition Radiator (8023) is a premium, professional-grade cooling solution engineered for demanding racing applications, high-horsepower engine builds, and custom motorsport vehicles. Featuring CSF's exclusive B-Tube technology, a high-efficiency 52mm dual-row aluminum core, triple-pass coolant circulation, and TIG-welded construction, this universal radiator is designed to deliver exceptional heat-transfer performance under extreme operating conditions.
Developed for professional motorsport applications, the CSF R-1 Competition Radiator combines advanced cooling technology with the durability required for sustained high-load operation. Its universal configuration makes it suitable for custom engine swaps, turbocharged performance builds, V-mount cooling systems, and other specialized installations where conventional vehicle-specific radiators may not provide the desired cooling capacity or packaging flexibility.
One of the defining characteristics of the CSF 8023 is its triple-pass cooling configuration. Unlike a traditional single-pass radiator, which directs coolant across the cooling core once, the R-1 routes coolant across the core three times before exiting. This extended coolant flow path provides additional opportunities for heat transfer, helping manage elevated coolant temperatures in demanding performance applications.
At the center of the radiator is a 52mm-thick, two-row aluminum cooling core. This substantial core provides a large heat-transfer surface while maintaining a relatively compact profile suitable for custom motorsport installations. The radiator's overall dimensions measure approximately 29.3 inches long, 19.1 inches high, and 2.55 inches thick, excluding the AN fittings.
The CSF 8023 incorporates the manufacturer's exclusive B-Tube technology, which utilizes specially formed aluminum tubes designed to increase the effective heat-transfer surface area compared with conventional oval radiator tubes. CSF reports approximately 15% greater tube heat-transfer surface area through this design, allowing the radiator to provide improved cooling efficiency without relying exclusively on additional core thickness.
Complementing the B-Tube construction are 8mm multi-louvered cooling fins, engineered to maximize the interaction between incoming airflow and the radiator's heat-transfer surfaces. The fin arrangement is developed through CSF's testing procedures to balance airflow characteristics with effective heat dissipation.
The R-1 radiator features 100% all-aluminum TIG-welded construction, providing excellent structural strength and durability for demanding automotive environments. Its aluminum end tanks and precision-manufactured mounting provisions offer a robust foundation for custom radiator installations.
For high-performance coolant plumbing, the CSF 8023 incorporates AN-style coolant connections, with a -16AN inlet and -20AN outlet configuration. These connections are particularly attractive for custom cooling systems utilizing braided or lightweight performance coolant hoses.
Another major advantage of the CSF R-1 is its suitability for V-mount turbocharged cooling configurations. V-mount systems position the radiator and intercooler at opposing angles to improve packaging and airflow management in certain high-performance chassis. The universal construction of the 8023 provides additional flexibility for builders developing these specialized cooling arrangements.
The radiator features a smooth satin aluminum appearance combined with a black powder-coated cooling core, creating a professional motorsport finish while providing exterior protection.
The CSF R-1 has been tested in professional motorsport environments, including applications associated with Formula Drift champion Michael Essa. Its development includes extensive testing for thermal performance, vibration resistance, pressure integrity, and long-term durability.
Whether building a turbocharged K-Series Honda, developing a custom Acura race car, or engineering a high-output drift or time attack vehicle, the CSF 8023 R-1 Triple-Pass Competition Radiator provides advanced cooling technology and the fabrication flexibility required for serious motorsport applications.

The CSF 8023 incorporates the manufacturer's proprietary B-Tube cooling technology.
Unlike conventional oval-shaped radiator tubes, CSF's B-Tubes feature a specially engineered internal shape designed to increase heat-transfer contact area.
The tube construction also allows CSF to utilize relatively thin aluminum material while maintaining structural strength.
According to CSF, this design provides approximately 15% more tube heat-transfer surface area compared with conventional oval tubes of similar external dimensions.
The result is a cooling core engineered to provide efficient heat transfer without relying solely on increased radiator thickness.
52mm Dual-Row Cooling Core
The R-1 features a 52mm-thick, two-row aluminum cooling core.
This configuration provides substantial heat-transfer capacity for custom performance applications.
The dual-row design increases the amount of cooling surface available within the radiator assembly.
When combined with CSF's B-Tube technology and multi-louvered fins, the core provides a performance-oriented solution for engines operating under demanding thermal loads.
8mm Multi-Louvered Cooling Fins
The radiator incorporates 8mm multi-louvered cooling fins.
These fins are designed to increase the interaction between incoming airflow and the cooling core.
CSF develops its fin designs through testing intended to maximize heat rejection while maintaining appropriate airflow characteristics.
For best results, the radiator should be positioned where sufficient airflow reaches the core during vehicle operation.
All-Aluminum TIG-Welded Construction
The CSF 8023 features all-aluminum construction with TIG-welded end tanks.
This design eliminates the plastic end tanks commonly found on many factory radiators.
TIG-welded aluminum construction provides a strong assembly suitable for demanding automotive environments.
The radiator's satin aluminum exterior and black powder-coated core also provide a professional motorsport appearance.
AN Coolant Plumbing Connections
The CSF 8023 incorporates AN-style coolant connections.
Coolant Inlet: -16AN.
Coolant Outlet: -20AN.
These connections provide compatibility with appropriately configured performance coolant hose systems.
Because the inlet and outlet use different AN sizes, builders must plan hose routing and fitting selection accordingly.
The appropriate hose materials, connection methods, and coolant system components must be selected for the application's operating temperature and pressure.
V-Mount Turbocharged Cooling Applications
The CSF R-1 radiator is particularly suitable for custom V-mount cooling configurations.
A V-mount arrangement typically positions the radiator and intercooler at opposing angles, creating a V-shaped cooling package.
This layout can help improve packaging and airflow management in certain turbocharged performance vehicles.
The CSF 8023 provides a large cooling core and universal mounting flexibility for these specialized installations.
However, a successful V-mount system requires careful attention to airflow ducting, heat extraction, radiator positioning, and intercooler placement.
