New for 2014:
- CubCrafters' high-performance, 180 horsepower TITAN® 340CC engine, built by ECi and used on the Carbon Cub SS, gets a new magnesium accessory case that accepts a spin-on oil filter. The Company will include a thermostatic oil cooler bypass valve (vernatherm) as standard equipment in 2014. Together, these improvements reduce net engine weight by 1.5 pounds.
- The carburetor on the 340CC engine gets a new fuel nozzle designed to improve vaporization and distribution of the fuel/air mixture to all cylinders. The new nozzle employs a proprietary "perforation pattern" that promotes even circulation of the mixture, thereby increasing consistency of exhaust gas temperatures (EGT) and cylinder head temperatures (CHT) at cruise and higher power settings. By leveling EGT and CHT, the 340CC engine runs more efficiently, smoothly and produces increased power.
As with every other aspect of the Carbon Cub SS, the engine choice was meticulously scrutinized for weight savings and performance, alongside essentials such as reliability, safety and economy.
Toward those ends, CubCrafters worked closely with ECi, of San Antonio, Texas, developing the 340CC engine. The TITAN® 340CC engine is fully certified to ASTM standards for Light Sport Aircraft
Just as Carbon Cub aircraft are modern updates of the classic Piper Super Cub, the 340CC is a thoroughly modern version of the venerable Lycoming designs that have successfully powered Cubs for many decades. Therefore, any mechanic trained in the repair and maintenance of Lycoming is equally qualified to work on the 340CC.
Modern updates include dual electronic ignitions (no heavy magnetos) and lightweight accessory components. In addition, an innovative cooling plenum more efficiently directs airflow to the cylinders and oil cooler. CubCrafters created a new, less restrictive 4-into-1 exhaust design that weighs just 6.2 pounds (half that of comparable systems). The alternator mount was modified to fit closer to the crankshaft, making the belt shorter and lighter.
The result is an engine that weighs less than 250 pounds, and is rated at 180 horsepower for takeoff and climb, and 80 horsepower for continuous power settings. At cruise power, fuel consumption is as low as five gallons per hour. Used as specified, the engine has a 2,400-hour TBO.
