Injected alcohol comp ratio
Looking for some input regarding maximum compresson ratio on an Alcohol injected comp eliminator SBC.
The engine I'm working on is a 410 SBC B/ND engine ,not a very quick one. The engine currently has a c/r of 17.3 to1 ,which I have no problem with if it was a gas engine. I've always observed on other engines a lack of improvement when going over 15to1 on alcohol . My concern is that the volume of fuel to burn at the afr required for alcohol will be greater with the lower c/r ,theoreticaly making more power. does this make sense or am I mistaken about the benefit of fuel volume vs. c/r ?
