^ While it may be true that nitromethane is "stable" when exposed to an open flame, but combust in under extreme pressure (I.E. boosted engine cylinder pressure) and you have one extremely dangerous, violent fuel.
Not to mention, gasoline & nitromethane don't mix either.
I'm done arguing my point. If anyone on here is stupid enough to mix 3,4,5,10 different burnable "fuels" together risking parts, engine , or even bodily harm in search of butt dyno power.... be my guest Sir Newton
Maybe you can sell your recipe to the ricer crowd.
