Frequently Asked Questions about automotive racing products ls 5.3l holley efi
Needs. The Terminator is Holly's carburetor replacement EFI system it'll. Work in any application that uses a standard four-barrel 4150 style carburetor and manifold.
The EFI provides consistent performance, easier starting, and greater fuel efficiency.
Fuel System Requirements
The Sniper EFI system requires a high pressure fuel pump capable of operating at 60 psi. When selecting a pump and lines, be sure each component is designed to perform at high pressure. Holley offers a variety of fuel pumps, hoses and accessories to complete your installation.

The electronic fuel injection system was designed to optimize fuel consumption and reduce the amount of polluting particles emitted from the exhaust pipe. This device prevents the formation of carbon deposits that can be found in mechanical parts such as the fuel system, injectors or intake valves.
Electronic fuel injection replaces the need for a carburetor that mixes air and fuel. EFI does exactly what it sounds like. It injects fuel directly into an engine's manifold or cylinder using electronic controls.
EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. They optimize air/fuel ratios and ignition timing while compensating for other factors to maintain continuous optimum performance.
After installing the Sniper and running for a few weeks with the initial air/fuel settings as mentioned, I saw roughly 1 ½ to two-miles per gallon increase. Not only did the truck drink less fuel, it gained some drivability.
Every EFI system requires consistent, higher fuel pressure. The required pressure varies with the system, but 58psi is average for many popular systems. This means you'll need a high-pressure electric fuel pump, hoses, quality fittings, and a filter that can handle the high pressure.
Yes, to an extent. The carburetor regulates the air-fuel mixture by means of suction while an EFI system is able to deliver a much faster and accurate response through the use of injectors. EFI systems are able to run more efficiently and effectively which means fewer emissions and better fuel economy.
However, HP is also tied to the torque output. And, as we've mentioned, that's something EFI can significantly increase. So, from a functional side, it does, actually increase the HP of your car. It won't be a massive amount - but a noticeable one.
EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. They optimize air/fuel ratios and ignition timing while compensating for other factors to maintain continuous optimum performance.
At its most basic, the system works by comparing the throttle angle or "alpha" to the engine rpm, or "N." Once it knows what rpm the engine is spinning and where you've got the throttle it makes a few quick, like microsecond quick, calculations and then selects the correct fueling points from the map.
