Fuel Injector Sizing Program By Bowling & Grippo

This program allows you to determine the correct fuel injectors to use based on a few engine parameters. Two different programs exist - one computes the operating rate for a given injector size, and the other determines the injector size (in Lbs/hr) based on maximum RPM at Wide-Open-Throttle (WOT).

Input your Engine Cubic Inch Displacement (CID):

Input the Engine's Volumetric Efficiency in %:

Input the Engine's RPM at Maximum Torque:

Cylinders: Four, Six, Eight, or Twelve

Enter Injection Mode:

Desired Air/Fuel Ratio:

Injector Size (Lbs/hr):
