ok, ive been told that the stock injectors flow great, and i believe it. but if i did go with higher flowing injectors, say 30# or around there, would they just dump fuel all the time or only under hard acceleration. i dont want injectors that will kill my mileage and just pour gas all the time. im actually hoping for a slight increase with better atomization and faster/more accurate pintles

 

Why do you keep starting new threads when you've already asked the same questions in one or more of the other numerous threads you've started, that very knowledgeable people here are giving you answers ? No, I can't help you with your question, and my reply is useless, but come on already.

 

cause im new and just trying to figure this thign out zman

 

I know, LOL Sorry to be a buzzkill, but just give these guys some time to answer in the other threads. I know waiting sucks, but alot/most of these guys know what they are talking about. Starting a new thread isn't going to give you an answer any quicker.

 

ok. thanks for the help zman. ill start holdin my water

 

Welcome to DF btw. You won't find a better Dodge site.

 

lol, i kinda like seperate threads, it makes it easier to focus on one thing instead of typing out an entire essay to answer all the questions asked

 

the ECM will ony ask for as much fuel as the engine can use.

certain areas of the engine are monitered to dertermine the best air/fuel ratio for the given moment. things like Throttle position (TPS), Intake Manifold pressure (MAP), engine speed (RPM), ect. These signals are sent to the Engine Control Module (ECM) which then decides the amount of fuel to dump into the engine by regulating the Fuel injectors "pulse width", this is basically how long the injector stays open everytime it fires. the burnt A/F mixture goes through the exhaust and is read by the O2 sensor which reads the oxygen content. if there is too much oxygen in the exhaust, it tells the ECM to add more fuel, and vise versa.

By adding bigger injectors to a stock engine, you wont notice any power gains. bigger injectors are used when an engine is modded to the point where the stock injectors cant supply enough fuel to the engine to mantain a proper A/F mixture.

I know you have been talking about building a stroker, this may warrent bigger injectors, but you would have to ask someone who has done it.

 

But not 20 in one day! JK cool hand

 

zman's gotten edgy lately under the influence of all those drugs
