The modified Miller cycle (via turbo and late intake closure) is ideal - plus running at low RPM allows for flame prop. Agree with 100% option!
Univ. of Minnesota has a great project running 'wet' ethanol in conventional diesels via fumigation. Impressive gains that every old time diesel tuner knew about for years.
This is actually what Cat ACERT motors do. They are not considered a true Miller cycle engine but they do utilize late intake closure (hence the VVT actuators and their issues) and rely on huge amounts of boost at low Rpm (the reason they have twin turbos and make over 50psi with torque peaking very low.
