This part is legal for sale or use on Racing Use Only Vehicles

  • Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street.

WARNING: It is against the law to install this part on an Emissions Controlled Vehicle

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.
