Anything over ~50% ethanol will be a waste because the power/efficiency scale is a not a straight line, it’s exponential. Up to around 50% you are gaining a lot of the cooling abilities and the extra octane. After that you are adding a lot of fuel with very little return.
With my procharged f150 (flex fuel equipped, 550 whp) and my XKR175 (non-flex fuel, 500whp) I ran blended e85/91e0 mix to 93 octane, because regular 93 is not available locally. Both of those ran amazingly with the mix all year round with zero issues.
With my Ranger I’m running the same mix and getting 313/376 at the wheels tune only. I’m hoping adding the downpipe gets me closer to the 340hp I want. None of which would be remotely possible with the absolute crap regular gas we have around here. With a boosted motor, ethanol is race gas.
