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.
