Whipple FOAC CuNi Intercooler - 671-1471, Whipple, PSI, Universal

WHIPPLE FOAC CuNi INTERCOOLER

The Whipple FOAC CuNi Intercooler, known as the Father Of All Coolers, is a large-format marine and custom performance intercooler designed for compatible 671-1471 manifold designs, Whipple applications, PSI applications, racing applications, and other custom supercharged builds. Built around one massive 5" thick core measuring over 10" wide and 17" long, the FOAC is intended for high-output forced-induction combinations that require serious charge-air cooling capacity.

Whipple Coolers are used by professional marine engine builders and performance shops because of their cooling efficiency, corrosion resistance, and proven durability in demanding supercharged applications. This cooler is intended for properly configured marine, hot rod, racing, and custom performance applications where charge-air cooling capacity, water-flow capacity, and long-term durability are critical.

CuNi MARINE INTERCOOLER TECHNOLOGY

Whipple CuNi intercooler technology uses cupronickel water passages for corrosion resistance in brackish lake water and ocean saltwater environments. Unlike aluminum cores or coated cores that can corrode over time, cupronickel construction is well suited for harsh marine use. Copper-alloy air fins support efficient heat transfer, helping reduce charge-air temperatures and improve cooling performance under load.

The FOAC core uses Whipple bar-plate cupronickel intercooler construction with an offset fin design and 24 fins per inch on the air side, described as similar to running 48 FPI for increased effective surface area. The design is built to maximize thermal reduction in compatible high-boost and high-load applications.

PERFORMANCE AND DURABILITY

The FOAC features dual -20AN inlets and outlets to support high water-flow capacity in compatible cooler systems. The rugged bar-plate design and TIG-welded construction help the core withstand demanding marine and racing use better than many traditional extruded-tube cooler designs.

Cupronickel construction also provides a major durability advantage in high-load environments. Compared with aluminum, cupronickel offers a significantly higher melting point and stronger corrosion resistance for marine intercooler service.

This cooler is designed for compatible 671-1471 manifold designs, with machining required. It may also be used for custom PSI and racing applications when properly configured by the engine builder or installer.
