A Note About HP Estimates Above

These are all ballpark estimates and are greatly affected by an individual engine's displacement and volumetric efficiency. NA maximums are generally limited based on airflow. Boosted and Nitrous maximums are generally limited based on fuel injector capacity. All of these estimates assume gasoline. Adjust accordingly for E-85. Find your engine to be in one of the gray areas?  Contact us--we love to help!  You can use our Contact Page or click on the Sales Support fly-out to the right of this page to get real-time help.

Holley Sniper EFI--Look, No ECU or Wiring Harness!

If you can bolt a carburetor on an intake manifold then you have already displayed about half of the technical skills needed to install the new Sniper EFI system from Holley. Imagine--hard starts, hesitations, vapor lock and flooding are all replaced by EFI reliability at a cost not much above a high-end carburetor!

You see, Holley has done away with the ECU box entirely! The new Sniper family of Throttle Body EFI systems incorporates the ECU right into the throttle body. The benefit is obvious to most folks but allow us to elaborate. With the ECU built into the throttle body injection unit, there is really no need for a harness, in the traditional sense. Nearly all of the sensors are built into the throttle body, so all you have to do is add a few basic connections (like power, and plug in the wideband O2 sensor and a timing signal) and you're in business!

Feature Rich

But don't think that you're getting short-changed. Holley engineers were tasked with producing a system that would have virtually all of the features of the Avenger and HP kits--and they have accomplished just that. Want to add some of Holley's beautiful analog-display gauges? You can. Need advanced tuning capabilities? The included 2.5-inch touchscreen display can do that. This isn't just a good place to start your EFI adventure--the Sniper will support whateveryour hot rod goals may be in the future.
