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:

  • 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!

Simplify--Order yours as a Master Kit

Want to simplify both your shopping and installation process? Then opt for the Holley Sniper Master Kit! This kit includes virtually everything you will need to convert your carbureted fuel system over to one that will support your new Sniper EFI system: Inline fuel pump, filters, lines, fittings, and more. Adding this option means that there is no guessing, no additional shopping--get what you need right in the same box with your Sniper system, as paired by Holley's professional engineering staff.

A note about express and international shipping of Sniper EFI System with Master Kit:  Because of the way that Holley created the retail packaging for their Master Kits it more than doubles the size of the box.  Although the Master Kit itself only adds 4 lbs to the weight of the shipment, the shipping company charges based on increased size.  Therefore, as a service to our customers who request express and international shipping of their Holley Sniper EFI Master Kit, we will reduce the size of the shipment by removing the master kit components from their retail packaging.  The reduction of shipping cost is automatically reflected in your shopping cart.  If you need your express/international shipment to include the original retail packaging, please notify us and we will be happy to do so at the higher cost of shipping.  Ground shipments are free, of course, and will include the original retail packaging.

Self Tuning

Other than having two injectors rather than four, the new Sniper EFI 2300 gives no ground to the 4-barrel Sniper.  After you run the setup wizard it tunes itself based on your driving.  You can monitor and control all vital functions via the included 3.5-inch touchscreen and never come close to a PC.  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. This added software is not necessary for the vast majority of Sniper EFI users. But there are a few folks out there who wanted full-featured tuning capability. Well, here it is!

What can you do with the laptop software that you can't do with the handheld? Well, you can tune your Sniper to work with boosted engines up to 1 bar of boost (using the 2-bar map sensor that came on the Sniper.) It is important to note that this software deviates from the basic concept of EFI for Everyman. While it is easy to add the required USB Dongle, download the Sniper EFI Software, install, connect, and run, learning EFI tuning is challenging to say the least. But for only the cost of the dongle (the software is available at no cost) you can get started.  And we here at EFISystemPro.Com are excited to guide you in your learning.
