Big Shot Single-Stage Upgrade Kit - converts the Holley 4150 Cheater kit (02001) to a Big Shot plate

This is an upgrade kit intended to be used with the NOS Cheater kit, part number 02001NOS. It will use part of the existing Cheater kit along with the components supplied to create an NOS Big Shot plate kit, capable of power levels up to 300+ horsepower.

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 maximum power gains. Power output is adjustable from 200-300 horsepower simply by changing fuel and nitrous jets.

Single stage Big Shot systems incorporate an NOS Pro Shot nitrous solenoid, a variety of power jets, 1/2" thick spray bar plate, gaskets, nitrous filter fitting, -6AN supply line, -6AN bottle nut, nitrous and fuel solenoid to plate feed lines.

Big Shot "plate only" kits are available separately; part number 12510NOS

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.

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 the pistons, rods, crank and block. Use of high strength forged components, splayed mains, and a four-bolt block, with cylinder head studs are highly recommended. use only a high quality racing ignition system with timing control. Intake manifolds that have an individual opening for each carburetor throttle bore should not be used. Open plenum, single plane, or tunnel ram manifolds work best. Racing gasoline is required.

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.
