The fuel system was designed for E85 from the beginning. DW300 supports 600whp on E85 and my 75lb injectors will be the bottle neck at about 420whp at 90% duty cycle at 4 bar base pressure. You either want a full stand alone or nistune if your going 4bar base fuel pressure because JWT and enthalpy tune at 3bar.
E85 takes 30% more fuel than gas. Changing from 3bar to 4bar base pressure increases fuel flow roughly 30%.
75lb injectors=780cc
780cc injectors at 3bar base pressure= 900cc at 4bar base pressure
Don't attempt this without proper tuning!
