Reply to "Fuel Pump Recommendation"

8 litres per minutes sounds like you were running a little rich. With 700 at the wheels you had about 900 at the crank. For this HP, you should only need about 350lph for a BSFC of .5. An NA engine would run BSFC of around 0.6 and would need less fuel. Each Bosch 044 is a 255lph at 70psi and 300lph at 0 psi. One alone should of almost been enough. One 255lph pump can easily support 650hp under boost or 750hp on an NA engine.

In either case, even if you need two 255lph pumps, you can buy two in tank pumps for $120 each. Much cheaper than those exotic pumps, much quieter, and they have OEM reliability. My Bosch pump has ran for 15 years and 50,000 miles with only a very coarse inlet screen. I have known several people have problems with the Aeromotive and similar Billet or race pumps.

By the way, The Walbro Gearoter pumps are quieter than the Bosch Vane pumps.
