I have been going over and over on my return fuel setup for big power on e85 and I believe I have decided on a single external pump with a sumped tank. However, I am having trouble finding hard data on any specific pump that will hold the power. My car currently makes 915/940 mustang dyno on 21 psi, c16, and triple returnless. We are planning on 25-27 psi, and e85 so I need something to support at most, 1100whp. I see a lot on the Magnafuel 4303, but I have seen some people run out of fuel pressure at the 900hp range, and others make 1200+ with ease. Magnafuel did tell me I could run the 4303 with a boost a pump, so that is an option.
My car is a 9.5:1 4.6 with a single 78mm. I will be running 160lb injectors with a base of 40 psi.
Any input from those in that power range?
