Description
Holley Sniper EFI Stealth 4150 fuel injection systems feature four 100 lb.-hr. fuel injectors capable of supporting up to 650 hp naturally aspirated. The Sniper Stealth 4150 ECU is capable of fuel map self-learning and ignition timing control--improving idle stability, drivability, and wide-open throttle horsepower! These systems also include transmission kickdown provisions for GM TH350/400, 200R4/700R4 and Ford C4/C6 applications. The 4150 is available individually or in a complete Master Kit (see contents listed below).
ALL Sniper EFI Stealth 4150 systems feature:
* Bolt-on 4150 flange carburetor replacement
* Throttle body mounted ECU; no extra boxes to mount
* Supports up to 650 hp with four 100 lb.-hr. injectors
* All of the wiring exits below the rear fuel injector cover—for a completely stealth installation
* Timed spark part for vacuum advanced distributors located under the front fuel bowl—for easy access to the distributor
* Air entry is machined to fit most stock-style air cleaners with air cleaner locator provisions
* Only four wiring connections required (battery +, battery -, switched ignition, and RPM)
* External fuel pressure regulator required, set to a base pressure of 58.5 psi, such as 12-886
* Integrated ignition timing control
* High-resolution full-color touch screen for initial setup, tuning, and gauge displays
* Simple calibration wizard (answer a few questions about your engine and it creates the base map, then starts tuning on its own); NO laptop required
* Self-tuning ECU means you don't have to be a computer/tuning wiz to have EFI
* The included genuine Bosch LSU 4.9 wideband oxygen sensor provides real-time fuel map learn
* OEM-style TPS/IAC and fuel pressure regulator, for years of dependable service
* Included clamp-on oxygen sensor kit for 2.25 in. exhaust ensures a leak-free oxygen sensor installation, with stainless steel T-bolt clamps and a stainless steel (weldable) oxygen sensor flange
* Available in three finishes: shiny, ceramic black, and classic gold
MASTER KITS also include complete fuel system with an external fuel pressure regulator preset to 58.5 psi, 20 ft. of 3/8 in. Vapor Guard fuel hose, fuel pump, filters, necessary hardware, and bulkhead fitting to return fuel into the tank.
