Skunk2’s cutting-edge fuel rails are available in composite. Composite fuel rails are made using a proprietary carbon-impregnated, aerospace thermo-polymer composite—a material that’s 33-percent lighter, 60-percent stronger, and operates up to 100°F cooler when compared to aluminum and insulates fuel from both radiant and conductive heat transfer underneath the hood, resulting in increased horsepower and torque. Composite Fuel Rails also feature large 0.625-inch internal bores for superior fuel injector pulsation dampening, are machined with a smooth interior finish, and feature radius-cut fuel injector outlets for improved flow characteristics. The all new aluminum fuel rails are are made from 6061T6 aluminum, a material that possesses an ultimate tensile strength of at least 42,000 psi (300 MPa) and yield strength of at least 35,000 psi (241 MPa). Skunk2's all new fuel rails feature large 0.669-inch internal bores for superior fuel injector pulsation dampening, are machined with a smooth interior finish, and feature radius-cut fuel injector outlets for improved flow characteristics. Skunk2’s B-series fuel rails can support up to 1,200hp, with gains as high as three percent realized during testing.
