Okay here is a question I have been trying to find information about, but nobody seems to have the correct answer.
When people talk about a fuel injector's flow rating they normally describe it using the cc's which im guessing is cubic centimeters.. for example 315cc, 440cc, 550cc... etc. Now in some cases people say that the flow rating is determined only by the fuel pressure while some say it is the voltage sent by the ECU. This is where my question comes in... which is which..
For example, from what I have heard the stock early model 3s-gte injectors were rated at 440cc and the later model 550cc. Some people say if you were to put the 550cc injectors on the engine without raising the fuel pressure to that of the later model engine... the injectors would only yield a flow rate of 440cc... or something else.
Wouldn't having the bigger injectors flow more fuel no matter where the fuel pressure was at? With the ideology that injector flow is controlled mainly by fuel pressure... you could say that if you ran the right pressure, and the injectors ran off of the same voltage... you could essentially put 550cc injectors even on a stock 4age engine and not run rich... which I think is false... so which is it???
