interesting theory I have - anyone with knowledge of head flow & mixture quality, please help
Ok, here is my question:
-A V-AFC will, in the end, decrease or increase the injector pulse width, correct?
-a FPR will simply put more or less 'force' behind the fuel, so that the fuel sprays out harder/weaker (i.e. more / less) for the same injector pulse.
as far as mixture quality, what would produce more power? (if any difference at all) - a very strong, but short pulse (very high fuel pressure with a very short pulse width) or a weaker fuel flow, with a longer pulse?
basically - a strong, fast burst of fuel into the incoming intake charge, or a slow, easy, longer stream of fuel into the same incoming intake charge.
This is assuming a N/A setup.
Is this a good question, or do I have to much time on my hands?

vafc..thru map sensor voltage manipulation. the best combination is a compromise between all variable so they can work as a cohesive unit w/o relying on one variable too heavily. On na setup for hondas, nothing more than around stock fp should be needed if yo have appropriate injectors, piggybacks and PUMP. If i had to answer this, i'd say the short hard burst because it feels good...i mean..it promotes better fetilization..i mean ATOMISATION! damn.
