Skunk2's composite components are made using a proprietary casting process, from a carbon reinforced aerospace thermo-polymer composite that is 33% lighter, 60% stronger, and runs up to 100ºF cooler than aluminum. Keeping the air and fuel cooler results in a significant increase in horsepower and torque. This composite is also chemical resistant to all types of fuels including alcohol. This material insulates the fuel from both radiant and conductive heat transfer under the hood. Keeping the fuel cooler results in an increase in horsepower and torque. Skunk2 has seen power gains of up to 3% in real world testing. Skunk2 composite fuel rails feature a large 0.625' internal bore with radius inlets to the injectors thus improving flow characteristics. This type of radius injector inlet design is not possible with extruded and drilled aluminum fuel rails (which have sharp angles internally where the main bore meets the injector bores). Skunk2 fuel rails can be used with factory fuel lines and fuel regulators.
Large 0.625" internal bores help dampen injector pulsations and can support up to 1200hp. Radiused injector inlets for maximum fuel flow. Smooth interior finish and radiused injector outlets are not possible with extruded and machined aluminum fuel rails.
