An injector that is stock on a stock engine runs at say 50-75% of injector width depending on load.
Install a blower, turbo, or Nos, Now that stock injector is running at 100% or even trying to get more, now the spray pattern becomes a garden hose.
Install larger injectors on the FI engine and now it is pushing about 50-60% again with a better spray pattern and not working near as hard to produce as the stock ones did.
The fuel pumps with the FMU's are awesome and a "cheap" way for Paxton to deliver the product, and it works.
But in upgrading the system, now the FI is capable of producing more power without straining the system, with less likely failure.
These are just my views, maybe Boomer or Nowwhat will chime in on this and give theirs, also I am still old school in the way I do things, if its simple and less complicted with less things to go wrong, I like it
Sorta like the old days, you build up your ford or chevy , you installed a bigger carb and better fuel pump to supply it.
A lot of thought in your post...spray pattern is more critical than most care to think about. A hose stream may put lots of fuel into the chamber, but everyone is looking for the finest mist so that there is optimum mixing of fuel and air. Beyond that, the specific placement of that optimumly mixed fuel air combination in the chamber is also critical. Hence the use of baffles in the latest intake manifolds. Those baffles direct the fuel mixture to the precise point that makes the best use of the explosive nature of fuel.
This is really getting fun!
