so im planning a tc76 turbo 5.3l out and i need to tackle the fuel system and make sure it can support a fair amount of power so i have room to grow.

-siemens deka 80# injectors
-Aeromotive A1000 fuel Pump
-Aeromotive A1000 Fuel Pressure regulator
-12 Gallon RCI Fuel Cell with Sump and -8an outlets
- (-8an) Pushloc Fuel Feed Line
- (-6an) Pushloc Fuel Return Line
-Edelbrock LS1 Fuel Rails

whats a good base pressure to run with E85? and whats the top power this fuel system can feed? im hoping around 600 with the 5.3l and when i put in my 6.0 im building ill be looking closer to 800... Input please

FWIW, my last car was a 99 Mustang with a custom return-style fuel system (stock system was returnless). With an A1000 pump and 80lb injectors, -8 feed and -6 return lines, I started losing fuel pressure at around the 600rwhp mark with a turbo, 5-speed car. I swapped to a Weldon 2025A pump and it was fine up to just under 700rwhp, which is the most the car ever made. This was with about 58-55psi base pressure with a 1:1 Aeromotive boost referenced reg.

If you like Aeromotive stuff, and mine worked fine for me, maybe just get an Eliminator pump and be done with it. Not much more expensive.
