I have a question: what does the multi-fuel combustion chamber design configuration do to control flame propagation? Would not a slower, more complete fuel burn have a limiting effect on timing and therefore max revs?
In other words, will it be necessary to throw out the whole multi-fuel design in order to make meaningful increases in power?
If so, I say why bother? Modern direct injection motors with variable geometry turbos make the kind of power that will cost you thousands to duplicate. Maybe it's fun to recreate what someone has already done, but I'm prone to spend as little as possible!
