The NOS Big Shot systems use a special “fogging” plate design that vastly improves nitrous flow, fuel atomization and mixture distribution. This Big Shot plate utilizes a unique spray bar that is equipped with tiny orifices. These are precisely located to efficiently dispense a powerful nitrous/gasoline mixture for unbelievable horsepower. An NOS Big Shot system can create as much as 400 extra horsepower. Power output is adjustable from 200 - 400 horsepower simply by changing fuel and nitrous jets.
Single stage Big Shot systems incorporate a NOS Pro Shot nitrous solenoid with -6 AN nitrous supply line. Systems include a variety of power jets , 10 lb. nitrous bottle, 1/2” fogging plate, filters, fittings for fuel and nitrous, switches and all electrical and other hardware necessary for installation.
Universal systems are available as well as kits dedicated specifically to Ford 5.0L V8 applications. Systems for import applications are listed separately in this catalog. Other kits are offered that enable one to upgrade a NOS Cheater system to Big Shot nitrous power. Big Shot fogging plates are available separately.
Actual performance gains will vary depending on the engine’s condition, configuration and jetting of nitrous system. Optional power jets are available for a variety of horsepower settings.
The amount of power you obtain from a system is dependent on the engine it is being installed on.
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.
