How to choose right fuel system to match turbo?

[eclipsek17]

I am new to turbo setups and am still learning as much as I can about them. I was wondering how you find the right fuel system for a specific turbo. I have not decided completely on what turbo I want to go with yet, but is there some way to know what size injectors and fuel line you would need for a turbo? What are the AN sizes?

Starting simple..

First define your power or ET/Trap speed goal

Pick your fuel

Choose your turbo/cam combo/compression combo

Rough VE estimate across desired or expected rev range will be used to determine engine demand flow

Plot this on your compressor map to see what combination of boost pressure and rpm you need to meet the massflow required to hit your goal(s)

Pick the injector you need that can support that maximum mass flow under worst case rich tune at only 80% IDCs.. I usually use 10.5:1AFR for pump gas, as an example.

Then pick the fuel pump(s) that can support that mass flow under worst case rich AFR and combined fuel pressure (base plus boost) at lowest expected voltage.

Use feed lines that can support that fuel flow with highflow filters.

Pick a return line of appropriate diameter and an adjustable regulator that can pass enough fuel to run your lowest desired base pressure
