Tech Resources

To supply the proper amount of fuel to the carburetor and the Powershot System, a fuel pump must be used that is 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 Powershot System is activated will require a fuel pump that flows at least 35 gallons per hour at 6 psi. Actual performance gains will vary depending on the engine's condition and configuration.
This system is not adjustable.
