More power! FiTech Go EFI 8 Power Adder Plus 1200 hp fuel injection systems are for gearheads interested in major power for road courses or the racetrack, while maintaining overall drivability. These systems combine eight high-flow injectors with an annular discharge increased to 20 streams to handle the massive flow. They fit any 4-barrel intake manifold, and are designed for use on engines from 250 to 1200 hp. The Power Adder Plus features a built-in fuel pressure regulator, an ECU that finds the best tune and self-adjusts to it, and the ability to change air/fuel ratios and ignition timing on the fly. To obtain complete atomization, FiTech uses a swirl spray annular discharge called Wet Flow technology, spraying the fuel in from multiple directions. Go EFI 8 systems with mounted ECUs offer spark control without the need for an external spark box or special distributor. To lower temperatures and extend the unit's life, FiTech uses a voltage-controlling fuel pump control, reducing the juice under low loads. Each system has a hand-held controller with touch-screen for initial setup, throttle linkage that suits most transmissions, and is manufactured with OE engineering. Take on the day, no matter what it brings—with FiTech Go EFI 8 Power Adder Plus 1200 hp fuel injection systems. Additional features include: * Choice of three fuel inlet connections * Will work with CDI box, but not required to control timing * Two adjustable fan control switches * Can be used with an engine-mounted returnless fuel command center * Uses easy-to-replace GM-type sensors and Bosch 4.2 wideband oxygen sensors * Nitrous and boost timing retard strategies and target A/F options * Air conditioning idle speed input kick-up * Many safety features and accessories for nitrous tuning control * Can handle 25 lbs. of boost from a blow-through turbo, blower, or single roots supercharger—and can also take a single stage of wet nitrous * Designed for applications making at least 6 inches of vacuum at idle. * Complete tuning from Pro Laptop software, with 8GB of data-logging

FiTech Go EFI 4 PA 600 hp system/Go Spark fuel injection master kits are inclusive EFI kits with fuel delivery solutions, plus an upgrade to high-powered sparks for improved combustion and power output. In these master kits, FiTech mates their Go EFI 4 Power Adder TBI with their Go-Spark CDI ignition and either a Go Fuel in-tank or fuel cell pump module, or Go EFI in-line pump kit to provide everything needed to convert your carbureted vehicle to EFI. The throttle bodies are available in different finishes. Choose the master kit with your preferred finish and fuel delivery solution. Go EFI 4 Power Adder system can support up 21.7lbs of boost right out of the box, as well as a single stage of wet nitrous. The air/fuel ratio is monitored and adjusted with FiTech's fast reacting self-learning technology, plus the ignition timing can be controlled based on boost or nitrous (including a retard feature). A touch screen handheld controller, cable and windshield mount, throttle body vehicle side harness, WBO2 sensor, bung kit, coolant sensor, gasket, mini USB cable, Pro-tuning laptop software, instructions, and warranty info is included. Go-Spark CDI ignition produces a series of multiple sparks below 2,500 rpm to improve starting, idle quality, and throttle response. At higher rpm, the CD technology continues to deliver full energy sparks through racing rpm to ensure complete combustion of the fuel mixture. Designed for 4-, 6-, and 8-cylinder engines equipped with a distributor, Go-Spark accepts the trigger signal from an HEI, amplifier, points, or 2-wire non-magnetic pickup distributors.
