Pabs, you have a chemistry degree, if I remember correctly so you may be able to apply the relationships of your home brew to say Fuel Power and 4 key effects of fuel and adds to help aid combustion.
FP has about 1 OCTANE boost capability but not intentionally this is an after affect of the next three areas and formulation of FP. This is pump octane (R+M/2). Your on target there based on my limited understanding of chemistry and your mix.
FP affects BURN SPEED of the fuel mixture. Speed at which fuel releases its energy. Real time not crank speed. Peak cylinder pressure should be at 20 degrees ATDC. If you try to burn fuel past this point it does not contribute to optimum cylinder pressure. Which is what these see at the
FP increases the ENERGY VALUE of the mixture the CC sees. Expressed in BTU's per lb. As air fuel ratios are measured by weight not volume. Potential energy values can be measured at any compression ratio or RPM.
FP COOLING EFFECT; relates to heat of vaporization, the higher the heat of vaporization the better its effect on the cooling of the intake charge( mixture).
Big deal in your rice grinding 2 strokes !!! Helps some in 4 stroke engines.
If you can figure out the optimum in your formula on these 4 areas you may be able to make some money with your brew !
I only know what I have learned about engines and analysis, I'm no fuels guy or chemist...
I do know that FP contributes to accomplishing these 4 key areas, pretty reasonably cost wise.
