FAST XFI 2.0/XIM Super Cobra Jet Engine Harnesses

FAST XFI 2.0/XIM Super Cobra jet engine wiring harnesses are designed to integrate with the factory vehicle harness, switch panel, and other components of Cobra Jet engines. It's the same system used by top NHRA and NMCA Stock Eliminator and Super Stock racers such as Anthony Bongiovanni, Gary Richard, Jeff Roell, P.B. Candies, Randy Eakins, Roy Hill, Don Bowles, Susan McClenaghan and Chuck Watson. The wiring harness offers several mounting options for the ECU and ignition module. It also features heavy-duty heat and abrasion-resistant sheathing with heat-shrink-sealed ends on the underhood portion. There's double EMI shielding on critical harness leads, plus durable braided nylon sheathing on the under-dash portion of the harness. It's compatible with Ford 5.4 Modular and 5.0 Coyote engines, either naturally aspirated or supercharged. Each harness includes a detailed vehicle-specific installation guide for integrating the engine harness to the factory switch panel, factory Launch Control/2-Step function, and factory gauges. This allows for simple data-logging of factory-installed sensors like fuel pressure, oil pressure, and brake pressure into the XFI 2.0 ECU. No cutting or trimming is required if the FAST XFI 2.0/XIM Super Cobra jet engine harness is installed as directed. This saves 30-40 hours building labor and results in a neat, factory-appearing installation. Every harness is also 100 percent tested to ensure optimum performance.

Ford Performance Parts Super Cobra Jet Cylinder Heads

Ford Performance Parts teamed up with Jon Kaase to redesign their 429 Cobra Jet cylinder heads, and the results are these Super Cobra Jet heads. They feature revised valve angles and locations to reduce cylinder wall shrouding and improve flow, along with redesigned combustion chambers to accommodate the more centrally located valves. These heads use the same valves, valve springs, retainers, and 7/16 in. stud-mounted roller rockers as the current Ford Performance Parts 429 Cobra Jet heads, and the standard Cobra Jet intake and exhaust manifolds bolt right on. This new design offers a 25-50 HP increase over current Cobra Jet heads, depending upon displacement and camshaft.
