Option B Big Bore HPFP and +30 or +65 injectors
Obviously option B is more expensive, but I'm wondering if option A would make the HPFP work too hard over time and fail and then I lose the motor 
I've seen a few do option A, but has anybody done option B? What kind of power did you make? |
E85 at that power level can be difficult. If you're serious about it you really need to go all out on the fuel system. Low side, high side, cam and injectors. Remember E85 requires 30% more fuel which is already a pressure commodity on these engines. It's easier and cheaper to make more power by adding boost instead of E85 if that makes sense. If you're looking for 800rwhp I would do the low side and a cam. You can probably get by with just the low side upgrade but your high side will be pretty tapped out unless you overdrive the cam.
