Sniper 2GC Small Bore

Rochester Small Bore 2GC Sniper EFI systems comes packed with two 100 lb/hr fuel injectors that will support up to 350 horsepower and a 2 bar MAP sensor that can read up to 14.7 psi of boost.

If your goals exceed 350 horsepower or boost pressures above 14.7 psi, we recommend using an intake manifold with a different bolt pattern, such as the Holley 2300 2-barrel or Squarebore 4150/4160 and the corresponding Sniper EFI unit as well.
