FUEL INJECTION TUNING HELP FROM THIS MANUAL: Racers throughout the world rely on racing mechanical fuel injection for high output power levels. Those polished stacks, scoop, or huge throttle body fed by individual fuel lines all indicate high power outputs. Tuning the jetting produces a win or loss, DNF or DNQ a race engine in one piece or broken. Simplify your tuning with easy to use lookup tables with detailed technical information. Math secrets to fine tune your jetting adjustments are revealed.

Jetting for normally aspirated big block V-8 engines from 400 to 1000 cubic inches (6.6 to 16.4 liters)

This is the second in a series of manuals about jetting for mechanical fuel injected race engines. The first was for the small block. This manual is specific to larger big block V-8’s on methanol. Info on nozzle sizes applicable to 2, 4, and 6 cylinder engines or any number of cylinders is provided. Setup & tuning of a methanol fuel injection engine is done with proper fuel pump size and jetting. Even after a proper fuel pump size is determined, tuning with jetting can be an endless task. This includes variations from engine component changes and weather changes. While the adjustments are few, their numbers of combinations are large. Because of that, this manual provides the following:

• Science of tuning with jetting
• Math for how to determine the jetting basis
• Jetting tables to illustrate individual tuning trends
• Additional jetting tables for various engine sizes.
