OCD850HE Triple-Pass Heat Exchanger

Built for Cobras that see real high boost abuse in standing mile, roll racing, back-to-back pulls, and high ambient driving conditions.

The OCD850HE was engineered to control IAT2 where it actually matters;  sustained pulls, repeated abuse & quick recovery.

At its core is an 850 cubic inch high-efficiency triple-pass design. Paired with dual 1.25” internal flow tubes and optimized routing, it increases coolant velocity and heat transfer without choking system flow or overworking the pump.

This isn’t a repurposed GT500 adapted design.  This is a purpose-built solution for the 2003–2004 Cobra. Engineered to work with modern high-flow components for maximum real-world performance.

Key Highlights

• 850 cubic inches of core volume
• True triple-pass configuration for increased heat rejection
• Dual mega 1.25” internal flow architecture for higher coolant velocity
• Full-width core to maximize usable airflow through the bumper opening
• Optimized around high-flow systems (EMP WP29/32, upgraded intercoolers)
• Improved temperature stability under sustained load with faster recovery between pulls

Who This Is For

• High-boost Cobra setups
• Drag Racing, standing mile, roll racing & repeated pulls
• Hot climates and extended driving conditions
• Owners who want maximum system recover and lowest IAT2's under real world driving

Why It Works

Cooling performance isn’t just about size—it’s about how effectively heat is moved.

More Volume
Increased thermal capacity delays heat saturation.

Higher Coolant Velocity
Maintains flow speed to improve heat transfer efficiency.

Balanced Airflow
Designed to use available airflow effectively without unnecessary restriction.

System-Based Design
Engineered to work with modern high-flow pumps and intercoolers resulting is quicker IAT2 recovery.

Real Results

This isn’t controlled demo testing.

Every aspect of the design was validated through extensive real-world testing to ensure compatibility with high-flow cooling systems and sustained performance demands.

These are real cars, real conditions, and real data under load.

Built in the USA — By Design

Designed, fabricated, and assembled in the United States.

Built with full control over materials, construction, and quality—so what you install is exactly what was tested.

Important Note

Cooling performance is system-dependent.  Results will vary based on pump flow, airflow, intercooler efficiency, and overall system configuration.  *Due to small production volumes there can be variances in inlet/outlet method that may differ from the product images above
