After four hours of reading posts on here and ls1 tech this is what I've come up with. IFirst off, I am running a 383 with a P-1SC @ 8.5 psi. At 4600 or so my fuel pressure starts dropping and at 6000 Im at 20 psi. I have a racetronix kit with an aeromotive Adj FPR set at 55 psi. Im running 50# inj @ 125% DC. I know this isnt enough injector, thats where the meth will come in. My question is will a dual intank setup fix my current pressure problem as well as supply enough pressure for future boost levels. I am just looking to get the most power out of my current setup but I also want to make upgrade only once. Later on I will replace fuel lines if needed. Dont really want to go with a sump tank and external pumps. If this doesnt work I will consider a boost a pump but would rather do this if it will work. Does anyone have the racetronix dual pumps? What does it cost?
