I have first hand experience with E85. I run FIC1450s, one walbro 255 intank (hp), one bosch 044 inline (after the fuel filter, before the fuel rail), with a fuelab afpr. I made 650whp on this combo and straight E85 with voltage dropping to 12.2V under boost, not an ideal situation. IDC's did peak at 106% IDC's with 32psi of boost, at a 38psi base fuel pressure. I can guarantee this combo, with base fuel pressure set too 45psi and voltage that can sustain 13.3V under boost will power 700whp worth of ethanol. I can almost guarantee 750-800whp w/a single boost-a-pump on just the bosch 044 working at 17+ volts on ethanol. I for one will be seeing how far I can push this system, my goal is 750whp. FWIW, the pumps are wired in series, also no re-wire done to the pumps as well.
