When you are getting serious about 4-digit horsepower under your hood with boost or nitrous, Go EFI 8 Power Adder 1,200 hp systems are up to the task. Plus, with FiTech's master kits you also get a high-pressure fuel delivery solution. FiTech Go EFI 8 PA 1,200 hp system Dual Force fuel injection master kits pair two powerful components designed to support serious horsepower. Go EFI 8 Power Adder bolt-on throttle body features eight high-flow injectors capable of fueling up to 1,200 hp. It is supplied with FiTech's Pro-tuning software and features the ability to data-log information. To ensure the best atomization of the fuel injection, the annular discharge design is increased to 20 jet streams to support the fuel volume required under boost, and has a built-in 2.5 BAR MAP sensor to handle the increased boost pressures, along with built-in timing controls based on boost or a nitrous input. The throttle body system includes 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. Go Fuel Dual Force fuel system supports up to 1,600 hp. The dual-pump system works in concert with a mechanical or electric fuel pump to supply the Force Fuel reservoir with fuel where it is then fed through two internal 340 lph pumps to feed the EFI system. Dual internal regulators keep the pressure at 58 psi which is ideal for reliable EFI performance. The assembly holds a 1/2 gallon of fuel to submerge the efficient pumps with no chance of fuel starvation. A strong, versatile mounting bracket is included for easy mounting under the hood.

The FAST XFI Sportsman EFI systems are a custom-tunable throttle body EFI that fills the gap between FAST EZ-EFI and XFI 2.0 systems. Designed for muscle car, late model street, race and sportsman drag racing engines, along with boosted and nitrous applications, the FAST XFI Sportsman EFI system is a fully software-tunable EFI setup. It requires a laptop for tuning and uses proven FAST C-Com software, which comes packaged along with the necessary USB connectivity cable. The system offers load-indexed speed density or Alpha-N tuning strategies; most users will use speed density strategy, which is self-tuning, but the Alpha-N option is specifically added to serve Sportsman drag racers looking for absolute consistency. The FAST XFI Sportsman EFI system features full tables to monitor fueling, acceleration fuel, timing, and air/fuel targets. A user-configurable auxiliary input channel and full-function data logging are also included. It supports both naturally aspirated and boosted applications up to 5 bar, is compatible with wet nitrous, and has nitrous timing retard control. Built-in CAN network support for the EZ-TCU, EZ-LS, XIM, and eDash means users can easily plug-and-play those components with the included CAN network wire. The FAST XFI Sportsman also features a Bosch wideband oxygen sensor, utilizes built-in diagnostic LEDs, a waterproof ECU enclosure and includes a premium, mesh-type wire loom multi-port harness. Plug-and-play with FAST Distributors, EZ-LS or XIM for electronic timing control—or use with an EFI distributor of your choice and a FAST crank trigger. The system can be used to control fuel only, and be used with a standard carb-type distributor where timing is set manually. The 8-injector, diecast throttle body features commonly available late model OEM sensors for accuracy and durability—and supports from stock to 1,200 hp engines. It flows more air than the first generation EZ-EFI throttle body due to an improved inlet, while a new secondary shaft throttle stop adjustment provides even more precise idle airflow adjustment and balance. Meanwhile, an industry exclusive and unique-to-FAST integrated fuel pulse damper creates ultra-precise fuel control and allows return or return-less style fuel systems to be used. This throttle body also incorporates needle bearing supported shafts instead of bushings and an integrated fuel rail design with crossover for tighter packaging. Setup includes the market's fewest connection wires. The FAST XFI Sportsman EFI systems are designed to be one of the most flexible systems available. It doesn't matter if you're a weekend cruiser or the most demanding Sportsman class racer, FAST has you covered.

And, with FiTech's master kits you also get a high-pressure fuel delivery solution to take your setup from conventional to EFI. FiTech Go EFI 8 PA 1,200 hp system Dual Force/Go-Spark fuel injection master kits pair two powerful components designed to support serious horsepower, plus an upgrade to high-powered sparks for improved combustion and power output. Go EFI 8 Power Adder bolt-on throttle body features eight high-flow injectors capable of fueling up to 1,200 hp. It is supplied with FiTech's Pro-tuning software and features the ability to data-log information. To ensure the best atomization of the fuel injection, the annular discharge design is increased to 20 jet streams to support the fuel volume required under boost, and has a built-in 2.5 BAR MAP sensor to handle the increased boost pressures, along with built-in timing controls based on boost or a nitrous input. The throttle body system includes 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. Go Fuel Dual Force fuel system supports up to 1,600 hp. The dual-pump system works in concert with a mechanical or electric fuel pump to supply the Force Fuel reservoir with fuel where it is then fed through two internal 340 lph pumps to feed the EFI system. Dual internal regulators keep the pressure at 58 psi which is ideal for reliable EFI performance. The assembly holds a 1/2 gallon of fuel to submerge the efficient pumps with no chance of fuel starvation. A strong, versatile mounting bracket is included for easy mounting under the hood. 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.
