If you have great knock suppression you can run 12:1.
If not you may need 9:1.

The extra fuel "overfueling" helps some, up to a point.
Beyond that point, it adds to the destructive force and heat of detonation/ (leading to) preigintion.
Intercooling is more effective. (air to air) (water to air)
Water Methanol injection is more effective
both are more powerfull too.
