Times! Not all race cars can benefit from getting an instant boost of up to 400 horsepower, as is the case with the NOS Big Shot Single Stage systems. This is because the vehicle's tires and chassis may not be able to cope with the additional horsepower, resulting in a severe loss of traction. To provide for a more gradual application of power, NOS offers highly effective Big Shot Dual Stage systems. This kit converts your single stage Big Shot System into a Dual Stage Kit.

Tech Resources

Big Shot systems are designed for use on engines that have been extensively modified and intended primarily for competition applications. To supply the proper amount of fuel to the carburetor and Big Shot system, a fuel pump must be used that is designed to operate between 5 and 10 psi, with a flow rate of at least 0.1 gallons per horsepower per hour at 6 psi. High cylinder pressures are generated with the use of these kits, and this greatly increases the load on internal engine components.
