Default Fuel Injection/injector Q?

A user asked , Copied n paste from another bb ...

Can someone help me out here, if I have a fuel injector which flows at 200cc/min what fuel pressure does that apply to?

If I were to supply more fuel pressure to that injector surely it would flow more fuel??

eg, if stock fuel pressure is 36 psi at WOT and i am using 200cc/min injectors then if i were to raise the fuel pressure to 50psi at WOT then wouldnt the flow from the injectors increase??

What say you?

you would need to ask the manufacturer, or someone who'd flow tested it.

From memory its:

Sqrt( new pressure / old pressure) * old flow rate = new flow rate
