Hey i have a LS1 building the motor and running a turbo set up. Wanted to see how much the factory system would hold if i put two 255s in tank? Wanting to eventually run 15-20PSI with the turbo set up. Would like to do everything once the right way. What size injectors and what the factory fuel rails will manage?

 

Return or returnless fuel system and e85 or just 93 gas?

 

Return and 93 gas

 

I have 1 aeromotive stealth 340 fuel pump in the tank dash 6 fuel line with return and a adjustable pressure regulator on a 6.0 with 2.9 whipple on stage 2 ported L92 heads 600+ lift cam 8 lbs boost and injector dynamics ID 850 85lb injectors they run at 70 % duty cycle . we are running 39.5 lbs fuel pressure to get more volume
