Radiator Double Pass Drag Race Power Adder

The Radiator Double Pass Drag Race Power Adder from AFCO Racing Products is engineered specifically for serious bracket racers and drag racing enthusiasts who demand maximum cooling efficiency in compact engine bays. This double-pass radiator design is built for vehicles where traditional single-pass cooling systems cannot keep pace with sustained high-RPM competition driving. Whether you're running a naturally aspirated build or a forced-induction platform, this radiator ensures engine temperatures remain controlled during full-throttle acceleration and repeated passes down the strip.

The double-pass configuration forces coolant through the core twice in a single circulation cycle, dramatically increasing heat rejection capability compared to conventional single-pass designs. This design multiplies effective surface area contact between coolant and cooling fins, allowing the radiator to dissipate more BTUs per minute—critical when engine bay space is limited and cooling demand is extreme. The compact footprint of 12 x 11 x 18 inches makes this unit ideal for tight engine compartments typical of tube-chassis dragsters and modified street cars where weight matters; at just 7.42 pounds, it contributes minimal rotational mass while delivering race-proven thermal management.

Racers running alcohol, nitrous oxide, or supercharged combinations benefit most from this power adder's cooling capacity, as these platforms generate exceptional heat loads that stock cooling systems cannot handle. Installation requires proper plumbing integration with your existing coolant loop, water pump, and thermostat housing—most experienced mechanics complete fitment in an afternoon using standard automotive hand tools. AFCO's track-proven engineering makes this radiator compatible with both street and competition applications, earning trust from weekend warriors and professional drag racing teams alike.
