Holley Sniper EFI gives you all the power and reliability of electronic fuel injection at an easy-on-the-wallet price. It's a bolt-on carburetor replacement that is compatible with both single-carb and dual-carb manifolds and features a throttle-body-mounted ECU, so there are no extra boxes to mount.

2015 When Holley Performance introduced the original Sniper EFI system back in 2015, it kicked off a revolution in fuel injection conversions. The goal was simple: Make EFI simple and affordable for folks who're looking to make the jump without completely reinventing their vehicle's setup.

With all the injection bits installed, the engine once again leaves the test stand and makes its way to the dyno. Wearing the 21st-century self-tuning kit, the engine puts down 295 horsepower and 329 pound-feet of torque, making for a gain of 13 horsepower and 16 lb-ft.

Therefore, every time you drive, the Sniper will keep learning to get closer to your target Air/Fuel Ratio. It will rough in the base table in as little as 10 miles. In generally only takes a few hundred miles for it to get the Sniper fine-tuned, but it is heavily dependent on your driving style.

"Super Snipers have the ability to handle draw-through supercharging, as well as blow-through, whereas the normal Sniper only can do a blow-through boosted application.

EFI systems are able to run more efficiently and effectively which means fewer emissions and better fuel economy. Because fuel injection is more accurate, it is also said to be more powerful as well. EFI systems can account for changes in the atmosphere, air, and fuel while carburetors aren't as accurate.

Sniper EFI is offered in multiple styles and configurations, but it's the Super Sniper that's garnered the most attention from power-hungry gearheads. With eight, 100lb-hr injectors inside, and a 2.5bar MAP sensor, the Super Sniper can support 1,250 horsepower and boost pressures up to 21.5psi.

Idle Tuning is a very important part of tuning any EFI system, especially our self-learning units like Sniper or Terminator X EFI. Getting the throttle blades and IAC to work together will keep your fuel injected hot rod running smooth and predictable.

Disadvantages of fuel injection Substantially more expensive than carburetors. · Cannot be repaired with simple tools, have to be replaced, which is expensive. · Cannot be customized, unless you go for custom ECU maps, which again is expensive.

Increased Reliability EFI systems maintain optimum air/fuel ratios, eliminating random engine stoppages, oiled spark plugs and other problems associated with sub-optimal ratios. Carburetors tend to need frequent adjustments; EFI engines eliminate the need for repeated modifications.
