NOS Pro Two-Stage wet nitrous system gives you a moderate shot of nitrous at the line to get a solid start. Then, a second stage of nitrous gives you serious muscle through mid-track and the top end. This system is adjustable from 200-500 horsepower and uses a special dual stage plate design for excellent nitrous flow, fuel atomization and mixture distribution. Our Big Shot style Pro Two-Stage plate utilizes 4 unique spray bars equipped with tiny orifices precisely located to efficiently dispense a powerful nitrous/gasoline mixture for unbelievable horsepower gains.

To supply the proper amount of fuel to the carburetor and the Big Shot 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 Big Shot System is activated will require a fuel pump that flows at least 35 gallons per hour at 6 psi.
