Default Injector/fuel pump equation?? Need help..

How do I figure out how big of a fuel pump I would need when picking injectors. I’m talking in general. Is there a rule that I can use similar to the one used to find out how much injector is needed to support so much HP.. (X*8)/.47… I want to be able to calculate fuel systems and not have to rely on others.. Thanks guys!!!

Start Here

i'd personally start with a BSFC of .5 for NA versus .47

Never hurts to be on the safe side with fuel <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Do we have a dead head style regulator?

Nope

It's actually a returning system, but the stock regulator is in the tank
