ChillOut Systems 4 Inch Carbon Fiber NACA Duct

The NACA duct installs on a rear quarter window to direct fresh, outside cooling air through a 4" hose and into the ChillOut Cooler. We prefer to have a duct and hose setup to guarantee fresh and cool air into the system. The 4" is our preferred size as it does not need an inline fan.

Ultra light weight and wind tunnel tested, the ChillOut Systems 4 inch NACA duct provides over 55% more airflow than standard 3" NACA ducts. Used in conjunction with the 4" Neoprene Air Duct Hose and a 4" Carbon Fiber Air Plenum results in maximum cooling efficiency for your cooling system.

NACA ducts bring air into a vehicle with minimal increase in drag. The purpose of a NACA duct is to increase the flow rate of air while not disturbing the boundary layer. When the cross-sectional flow area of the duct is increased, you decrease the static pressure and make the duct into a vacuum cleaner (without the drag effects of a standard scoop). The reason why the duct is narrow, then suddenly widens in a graceful arc is to increase the cross-sectional area slowly so that airflow doesn’t separate and cause turbulence and drag.

ChillOut systems is a new approach to driver cooling with a focus on high quality components, minimal maintenance and downtime, and light weight. The heart of the system is the blower which produces as much cooling power as systems 5x its size. Next is the use of a unique coolant formula that does not rely on ice. This means more consistent cooling for a longer period of time and no lost time refilling a cooler. ChillOut Systems is nothing less than a total overhaul of driver cooling, designed by and for racers. We feel that even at a premium price point all of your expectations will be exceeded. All ChillOut products have a 18 month warranty.
