Ok, I need some hel as i am having a hard time finding what im looking for or how to calculate it. I know flow rate i need for injectors, but how can I select a smaller injector and run higher pressure to equal my required flow rate.
Injectors are advertised for flow rate at 43.5 psi. If i need to run 60 psi, then my selection of injector tested at 43.5 psi will have to be one that is of a lesser flow rate to compensate for the increase in pressure.
The reason why I want to run ~60 psi instead of ~43.5 psi is because there is a reason why Ford used 60 psi on the 300 and only 45 on the V8's.
The increase in fuel pressure helps to keep the fuel from vaporizing. The 300 fuel rail is much closer to the exhaust than a V8, so the heat absorption is much greater.
This is also why they used an injector cooler on some of the 300's to keep the injetors cooler. There is a larger concentration of heat on the pass side of the engine.
Do I need to calculate out an Injector flow rate dependant on fuel pressure? If so, how?
