Not all race cars can benefit from getting an instant boost of up to 300 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. These systems incorporate two sets of nitrous and fuel solenoids so that power can be added in two events. The first stage allows the vehicle to leave the line with a moderate performance boost, say 200 horsepower. Then, when the tires are "hooked up", you can push the button for an additional 400 takeyour- breath-away ponies. This first stage is activated by a throttle switch while the second stage is activated by pushing a button, or optional Precision Delay Timer (15838NO PI). Activation of the second stage automatically deactivates the first stage.

Two Cheater solenoids control the first stage while a Super Pro Shot nitrous solenoid and a high-output Cheater fuel solenoid control the second stage. A 10 lb. nitrous bottle is standard. Optionally available are a wide variety of NOS electronic controllers. These can be employed, for example, to activate the second stage, while a NOS Progressive Nitrous Controller can be used to actually dictate the amount of nitrous (in percentages of total power potentia PI) and the timing. 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

  • 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.

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.
