SNIPER EFI 4150 X-FLOW

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 1375 from Holley features 8, 120LB/HR Fuel Injectors and flows 900CFM allowing it safely supporting up to 800 HP on Naturally Aspirated engines or 1375HP with forced induction! 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 or 12-851 for Forced Induction, or you can select an entire fuel system in the drop down below when placing your order.
  • The 4 injector version is perfect for high horsepower N/A combo's, easily supporting up to 800HP.
  • For the 4150 Blow-Thru crowd, the 8 injector version supports up to 1375HP.

NOTE: STEVE MORRIS ENGINES has spent the time on our dyno to create custom calibrations for your boosted application.  We can supply a base calibration specifically for your needs!  Simply select the option during purchase and fill out your engine details on the product page for the specific Sniper EFI system.
