True, but at 50% methanol the Water/Fuel ratio has to be over 20% for the shift in the stoich point to become an issue, right?
Also the more the alcohol percentage, the less the atomisation deficiencies of petrol, and the cooler the burn, so one can go even closer to stoich at full boost.

Pump fuel, nice, so we can see some of the 'octane boost' effects in action!
