Tip:Calculate new injector flow based on pressure increase

So you know an injector flows 550cc at 40 psi, now you want to know how much it flows at 50 or 60 psi. This simple formula will allow you to calculate it quickly. Works for aux injection systems, fuel injection systems, hell it will even work on your sewer system if you really cared to know.

SQRT(New Pressure / Old Pressure) X Old Flow Rate= New Flow

We'll use the above 550cc @ 40psi base pressure as an example.
example: New pressure = 50psi, old pressure = 40 psi, old flow rate = 550cc

So hit square root on your calculator, enter 50 divided by 40, then multiply times 550= 687cc <---- this is your new flow
