At 45 psi (trying to find flow rate at 43.5 psi is too hard, so 45 psi is close enough and gives us a tiny cushion), we get 330 lph. Divide by 60 to get lpm and multiply by 1,000 to get cc/min and then divide by 4 injectors. I get 1375cc, so at idle, I have enough fuel for my RC1200cc (which is 1090cc).
