Introducing Sniper EFI XFlow! Are you building a naturally aspirated engine up to 800 Horsepower? Looking to convert your blow through carbureted turbo engine to EFI? Look no further! The Sniper EFI XFlow from Holley features 4, 120LB/HR Fuel Injectors and flows 900CFM allowing it safely supporting up to 800 HP on Naturally Aspirated engines. The XFlow comes with an internal 2.5bar MAP sensor that will safely work on boosted applications up to 21.5 psi. For applications making more than 21.5 psi, and has three additional 0-5v Sensor Inputs which can be used for an external MAP Sensor, or Dome Pressure for boost control, as well as oil pressure and fuel pressure. An External Fuel Pressure regulator is required; we recommend part number 12-848 for N/A applications.
