Im planning out my fuel system to go FI. I have dual 255s with -8an feed/-6an return and thinking of swapping those pumps out with dual racetronix 340s for flex fuel. Will my -8an feed be enough for 1200-1300hp motor? I have stainless 1/2” hardline so i can cut the ends off an re-flare them to -10an pretty easy. Since these pumps combined will give 680L/hr i was going to go with ID1700x injectors as they should give me a better idle as compared to the 2000cc injectors most run and the racetronix chart says they will be at about 80% duty cycle at 6500 rpm and 680L/h. Input wanted. Also i read somewhere that someone tested pumps and that the racetronix 340s flow more than the walbro 340s. Is this true or BS? I cant seem to find that again when seatching for it.
