Calling all Air/Fuel mixture guru's. Can someone tell me how these work?
1. I have 19# injectors. If I were to upgrade to 42# injectors would they shoot 42#'s all the time when they are injecting? Or are they variable via the computer or something else?
2. An example I am thinking about. For explanation purposes only, lets say I have a stock factory engine(1989 everything). I replace the 19# injectors with 42# will this put too much fuel into the system and cause problems?
3. Now lets say I have stock bottom, aftermarket aluminum heads, aftermarket lower and upper intake manifold, 70MM TB, 7psi supercharger. What happens with both 19# and 42# injectors? So with 19# would that be a bottleneck and I am simply shoving tons of air and little fuel so HP isn't what it could be or is something regulating the mixture even though the stock computer doesn't know about the supercharger(not tuned)? Then if I switch to the 42# will it simply be pushing 42#'s and still not regulated but since its shoving more fuel in with air I get more HP?
I want to understand this so I can do correct research on different combinations of aftermarket upgrades.
Thanks in advance.
