If you've landed here, you're lucky enough to have the most versatile flange in the Sniper EFI lineup. The 4150/4160 is compatible with Holley, Carter, Edelbrock, and other squarebore 4-barrel mounting flanges. From mild to wild, we have all of the bases covered. We have two standard Sniper EFI systems that come equipped with four 100 lb/hr injectors that will support up to 650 horsepower. This includes the base Sniper EFI and the Sniper EFI Stealth for those of you who want to maintain the classic looks of the squarebore carburetor you're replacing. These do come equipped with a 2 bar MAP sensor that will handle up to 14.7 psi of boost as well. Despite the aesthetic differences, these units are internally identical so there is no tradeoff for looks vs. power.
If your goals exceed 650 horsepower and/or boost levels over 14.7 psi, we have even more options for you. The Super Sniper 650, Super Sniper 1250, Sniper XFlow, Sniper XFlow 1375, Super Sniper Stealth 650, and Super Sniper Stealth 1250 all come equipped with a 2.5 bar MAP sensor that will handle 21.5 psi of boost and support up to 1375 horsepower.
But don't think we forgot about the dual-quad guys either! If you're running a tunnel ram, roots style blower, or another 2x4 intake, we have a lineup of Sniper EFI systems engineered specifically for you.
If you're making up to 650 horsepower and are naturally aspirated or on low boost (up to 14.7 psi), hit the link to select the correct Sniper EFI system for your combination
