help with fuel system I have made my decision on my turbo and my intake.Its time to start figuring out the fuel system and with this being my first Turbo motor I really need some help. The car is a 68 Camaro the motor is a stock 5.3 with an LS1 intake I have a 75mm B/W S400 turbo for it. I will run a TH350 tranny and the car has a 12bolt with 4.11s(will be changing to probly 3.31s). I am thinking of running a sumped stock tank or a fuel cell(just hate to loose trunk space) with an A1000 pump in line I was told a -8 supply line would do it. I don't know what fuel rails I'm going to need or injectors. The car is a budget biuld but I know the fuel system isn't the best place to save money. My goals are to run 550-600WHP at first then after getting used to it I would like to do a forged bottem end and run around 750-800WHP. I would lke to do enough fuel so I don't have to buy it again later if I can. I'm looking into E85 its available here but not everywhere and the car is going to be on the street a good bit I thaught about getting a 50-100 gallon storage tank for it just worried about running out on a long drive and not being able to find it anywhere. Any suggestions on fuel system parts would be very helpful. Thank you.
Doing it "right the first time" and being on a budget might not work out to well. I've got a turbo 4.8 in my car with the same trans and turbo you're going to run. I have a 15 gal. fuel cell with two Bosch 044's and a boost-a-pump. each pump has a -8 feed to each rail. (fast fuel rails) then they both go to an aftermarket fuel pressure regulator. and -6 return back to the fuel cell. I'm on 80lb / hr. injectors and am just about 100% duty cycle at 15psi. Probably about 600 at the wheels. I'm on E85
For e85 you need about 33% more fuel delivery so pump and injectors will need to be scaled appropriately. Even your future goals on pump gas are going to be hard for an a1000. There are much better ways of doing it right the first time give me a call I will help you get it setup for your needs.
Sumped tank or cell, twin Bosch 044's with one on Hobbs pressure switch. -10 feed and -8 return. The A1000 wont cut it for your future goals and 2 walbros would be close too. Use good filters such as Magnafuel or Kinsler Monster Mesh.
