Power output is adjustable from 190-300 horsepower simply by changing fuel and nitrous jets.

Bottle Notice for Part# 02101NOS
Instructions for Part# 02101NOS
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.
