Redesigned from the ground up, the Atomic 2 EFI system now features an 865 CFM throttle body with integrated ECU, full color touch screen, simple 4-wire hookup, and several easy-to-use new features! This master kit includes the Atomic 2 EFI unit, but also a complete fuel system with external fuel pressure regulator preset to 58.5psi, 20ft of 3/8" EFI Rated Fuel Hose, Fuel Pump, Filters, necessary hardware and bulkhead fitting to return fuel into the tank.
The Atomic 2 EFI features 4, 100LB/HR Fuel Injectors capable of supporting up to 650 HP naturally aspirated or 635 HP on forced induction applications. The Atomic 2 ECU is capable of fuel map self-learning and ignition timing control, improving idle stability, drivability, and wide-open throttle horsepower! Designed to fit on 4150 intake manifold, with ample clearance for factory air cleaners.
The Atomic 2 EFI provides the performance and drivability benefits that you expect from fuel injection. Quick starts, smooth idle and great throttle response just to name a few. Combine the fact that the Atomic 2 will support ignition timing (with the appropriate distributor) through the ECU and you have a win-win combination. Initial timing is handled through a compact handheld monitor where you simply answer a few car guy questions about your engine and you're off and running!
