Big Shot Nitrous Kit Holley 4150 Flange 190-300 HP - 10 lb Bottle

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. Power output is adjustable from 190-300 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, nitrous bottle, 1/2" fogging plate, filters, fuel and nitrous fittings, switches and all electrical and other hardware necessary for installation. Big Shot fogging plates are available separately.

Good to know

• 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.

Important: this product runs on nitrous oxide (N2 PI), a gas we do not supply and which is currently difficult to obtain. It is your responsibility to find a local supplier of gas for professionals. NOS bottles do not comply with CE standards (they do not carry the PI mark): only CE-approved bottles may be used. European manufacturers offer bottles approved to contain this gas; please check the applicable standards and verify the manufacturer's origin and compliance before purchasing. NOS fittings are not metric (AN / NPT threads depending on the part numbe PI): plan for the adapters needed for your installation. Please comply with the regulations in force in your country.
