Sniper EFI 2300: Performance EFI for Engines Under 325 HP
Ok, everyone has been patiently waiting while all of the big-horsepower engine owners have been beating their chests about the benefits of Sniper EFI. Well, your wait is over. Holley has come through big-time with the new Sniper EFI 2300 Fuel Injection System. How big? Consider first that over 1500 Year/Make/Model/Engine combinations rolled off the factory floor with the Holley 2300 carburetor. Add to that all of the hot rods that have been fitted with a Holley 2300 since then and virtually any vehicle to which a 2300 can be mounted and you'll recognize that Holley was aiming to please with this new system that makes EFI a bolt-on, self-tuning reality for every one of these.
Installation is well within the skill range of the average shade-tree mechanic. Bolt on the throttle body, put the linkage in place, connect the power and O2 Sensor, provide an EFI fuel supply. All that's left is walking through the guided setup quiz (with not-so-tough questions like, "what is the displacement of your engine") and the ECU located inside the throttle body itself does the rest.
Features:
- Available in Shiny Metallic or Ceramic Black
- Direct Fit for 2300-style Intake Manifold (adapters available for other manifolds)
- The ECU is in the Throttle Body--No boxes to mount, no complex wiring harness to run!
- Connect with as few as 4 wiring connections: Power +/-, Ignition, and RPM Signal
- Fuel pressure regulator and most sensors are built-in
- Visually amazing 3.5-inch touchscreen provides both setup and monitoring
- Self-tuning--no laptop or software required!
- Available in Shiny Metallic (550-849), Ceramic Black (550-850)
Self Tuning or Tune It Yourself!
Configuring your new Sniper EFI System couldn't be easier. Click the "Setup Wizard" icon on the included 3.5-inch handheld display and the ECU configures itself and tunes based on your driving. You can monitor and control all vital functions via the display. No requirement whatsoever for a PC/Laptop or software.
But if you are one of those who loves to dig in deep, the new 2-BBL Sniper EFI 2300 can be tuned with the same award-winning software available for it's 4BBL big brother. Simply put, there is no comparable EFI system software on the market--and it is yours to download at no cost. An optional CAN-to-USB Dongle is available to make the tuning process more convenient. Never used EFI software before? Don't worry--we here at EFISystemPro.Com are excited to guide you in your learning.
Recommended With your Sniper EFI System
- You will need an EFI Fuel System. We have several solutions!
- We always recommend one of Holley's OE Style Fuel Modules if one is available for your vehicle.
- A complete EFI Fuel Tank System is also a great choice.
- If no OE module or complete Tank solution is available for your vehicle but you still want the benefits of an in-tank pump then one of these Retro-Fit Fuel Tank Modules is the right answer.
- If you have a racing fuel cell with a 6- or 12-bolt flange around the filler neck then one of these Fuel Cell Tank Modules is ideal.
- The Master Kit with inline fuel pump continues to be the most cost-effective and universal solution. You can choose that when you add the EFI System to your cart, above.
- You absolutely will want a Fuel Pressure Gauge. Those who don't install one with their EFI system are invariably the ones who end up needing it.
- The Sniper EFI System has the capability to control ignition timing in addition to provide fuel injection. If you choose this then we recommend you upgrade to the HyperSpark Distributor System.
