New at Summit Racing: Quick Fuel QFI Electronic Fuel Injection System

Who better than the fuel system experts at Quick Fuel Technology to come up with a bolt-on throttle body EFI system that combines the advantages of a carburetor with modern fuel injection?

The QFI system can feed street performance engines making up to 525 horsepower. Where the QFI system differs from other designs is the way it delivers fuel. The patent pending, eight-hole annular discharge sleeves inject fuel into the venturis where air speed is at its peak and pressure is at its lowest. That means the QFI atomizes fuel far better than traditional fuel injector nozzles, producing a more homogeneous fuel/air mixture that burns faster and more completely. The result is more power and better throttle response.

The QFI system also has a unique idle supply circuit that supplies extra fuel below the throttle plates for near-instant startup.  Other features include:
• Self-learning ECU can be programmed via hand-held controller or laptop
• On-board ignition driver—no ignition box necessary
• Integral two-step rev control
• Compatible with wet flow nitrous systems, superchargers, and turbos
• E85-compatible with minor modifications

The QFI system includes the throttle body assembly with 66 lb.-hr. injectors, ECU, handheld controller, wiring harness, sensors, and laptop cable. A Master Kit is also available that includes everything listed plus an electric fuel pump, fuel filter, regulator, and fuel line. You even have a choice of a polished aluminum or Black Diamond coated throttle body.
