I have two goals with my truck (that are germane to this train of thought); I want to be able to drive around daily with no smoke, and I am going to fumigate as much alcohol into my engine as I possibly can.
In order to get the most out of alcohol, you need to run (relatively) retarded timing and have a good ignition source. To that end, I think I need an injector with a fine and wide spray pattern, but with a (relatively) small fuel flow rate.
From the very little I know about injector design, I think that translates into something with as many possible holes that can fit, but with all of those holes tiny. Large holes that give me more fuel than I will have time to burn are a liability; not only will they undermine my goal to be a smoke-free daily driver, but if I ever find myself with a lean mixture then the extra fuel would just smoke and afterburn in my manifold. And theoretically, smaller diameter holes let you add more holes in a given tip (in exchange for a smaller total hole area).
So I want an injector with lots of tiny holes and a wide spray pattern. Wouldn't a 9mm injector like I have be more suited to such a pattern than the 7mm injector? To compensate I'd have to get my head stitched to prevent cracks, but that's only supposed to cost $400... And I can just save up to do that along with the O-rings and porting that I'm going to need sometimes anyways.
At the moment, I need new injectors, which even if I were to go stock would cost $400. It would be one heck of a leap for me to spend the extra $800 or whatnot to get customs made, but if I can get some like I'm envisioning then I would be able to run them without too much modification to my existing set-up and not be over-fueled. And they'd be perfect for my long term goals.
But it also means that I'd be spending the $800 I have in the Emergency Injection Pump account...
So, could anybody talk me out of it or tear apart my reasoning for it? I'd be appreciated...
