Hello everyone,
I posted this same question on another site, but it isn't a place that is really into ecomodding. Thought I would ask here because folks here are in the same mindset. I was reading the other day on this link and, not being a real mechanic, had a couple of questions I'm hoping some of the "brain trust" here can answer. Here's the link........
Fuel Injector Flow Rate versus Fuel Pressure - Route 66 Hot Rod High
What I am understanding from the article is my '97 Ranger has the 14# injectors as did the '09-'01's. The '98-'01's with 2.5l had fuel delivered at 60 psi rather than the 40 psi in mine. This supposedly made the 14# injectors operate like 19# injectors. I am assuming this make for a HP increase.
These are the questions.....
Is there any truth to this article?
If it is true then how does the pressure change? Is it the different fuel pressure regulator or do the '98-'01 Rangers have a stronger fuel pump?
Again, if it is true, would changing out the stock 14# single hole injectors with 14# 4 hole injectors (maybe from a Focus with a Ztech engine) combined with the increase in fuel psi make for better fuel atomization?
Is this actually safe? The article states that 45 psi is about the safe limit for the 2.3l fuel system. If they had 60 psi in the '98-'01 2.5l then is it a "beefier" fuel system? Larger and stronger components?
The reason I am asking is I am always looking at getting better fuel mileage. I'm doing well now, but I'm always tinkering to find another couple of mpg's.
Thanks for the help.
