Torker II MPFI Build
If your leaving the bung full length...I would be curious what injector you have chosen.
There are many types with varying spray patterns.
if a standard conical spray I would be concerned with it just dripping down the sides of the bung. kind of defeats the whole reason they atomize the fuel.
There are some that shoot a stream and that may work fine to get the fuel into the air as it flows past.
Then you have the protrusion into the air flow. That is just reducing the CFM flow of the runner.
Most talk about the advantage of dry over wet runners in the extra CFM of air in the dry with no fuel vapor to take up space.
I try to run mine so the tip is flush or just above the runner ceiling.
But I mostly run a standard conical spray pattern.
V8 with Ford injectors, they have a longer tip.
