Fuel delivery CC questions. - Competition Diesel.Com

I hear guys talk about the amount of fuel they are running Like 900cc or 1000cc. What exactly do these numbers mean? Is this the amount of fuel injected per revolution? Is there a rule of thumb on how much bigger an injector should be when making large increases in fuel delivery volumes?

It's a measurement of fuel delivery used to base tune a mechanically injected engine .. Most of the time it's measured using a test stand injectors . Cc rating is per 1000 strokes of the injection pump

A few variables used to determine what size injector to utilize are, but not limited to. The general hp goal, cubic inches, pump output and the piston it is spraying into
