Edelbrock Carburetor Jet/Rod Fueling Calculator
The Edelbrock Carburetor Jet/Rod Fueling Calculator lets you compare you current
jet & rod combination with other possible combinations. It shows the relative percentage
increase in cross-sectional area of the jet/rod surface in both power/cruise modes
which will give a good indication of the relative fuel flow change. This will allow
you to choose your combination of jets and rods compared to your present jetting
rather than relying on the base calibration for your carb.
The percentages indicated in the results are relative to the area of the jet/rod
combination you select. For example, if you chose the 098 jet and 75/47 rods (Edelbrock
1406 base calibration) and wanted to go richer on both modes, one of the results would
be 101 Jets and 1459 (75/47) rods. This would give 108% Rich stage and 115% Lean stage. This means
that the rich stage would be 8% richer than the base calibration and the lean stage
would be 15% richer than the base calibration.
