Tech Resources

To properly supply the carburetor and the Sniper System, use a fuel pump designed to operate between 4.5 and 7 psi with a flow rate of 0.1 gallons per horsepower at 6 psi. For example; an engine that produces 350 horsepower when the Sniper System is activated will require a fuel pump that flows at least 35 gallons per hour at 6 psi. *Actual performance gains may vary depending on the engine's configuration and condition.
