x2. 80lbers could be pushed to 1Krwhp on gas but not safely if at all on e85. When designing a fuel system on an FI build, you need to overestimate your fuel requirements and "overbuild" your fuel system. Ideally you would have either one big magnafuel 4301 or twin walbros or bosche in tank pumps, all large ID braided lines, boost referenced FPR, and 96# injectors. Not a good idea to rely on an underbuilt fuel system to keep up at 1Krwhp+. Think of how much you have invested in your drivetrain...is it really worth it to jeopardize everything?

what pumps were you running that still flow good up at 80psi? 044's? Cuz i know walbro's will not flow anything after their pushed much over 65psi or so.
my 60#'s are 95% duty cycle @700whp base fuel pressure set @45psi then you add 16psi of boost and your running 61psi of fuel psi getting close to the flow limit of the twin walbro pumps. im switching to 80#'s very soon got them just waiting to go it and get retuned.
