Thanks for having me.
I guess I should start off by saying I have a scer with 9 pounds of boost and retarded the timing and all of the other safety buffers people reccomend.
What I found was when you gewt a larger fuel pump on a returnless fuel system like our beloved Z and you add too much fuel like say a 280L SARD you will have extra fuel.
The returnless system doesn't know how to regulate it so you can buy an FPR
Fuel Pressure Regulator.
My findings from 2 sources show that the stock pump flows like a mofo!
It's a tiny little thing (picture a can of Red Bull.) It is about that size exactly so it's moving some fuel!
The replacemnt that drops right into it's spot is a Walbro 155 and is the exact same size, even the same color!
It flows more but not obscene amounts more. I was in LA and saw 5 fuel pumps laid out. SDome were obscene when you see how dinky the stock and Walbro are.
Like picture a Monster Energy DRink can or .5 Farad Audio Capicitor as a visual guide.
The regulator and line is almost 300 more and I am trying to see if I can just drop the Walbro in there without an FPR and a line run through my car (tearing apart the inside of my car for like the 5th time.)
So I guess that will help make it make sense.
If the Walbro just adds enough to keep you inline with a 11-12 A/F ratio (what my ECU has been reflashed to run) would the FPR still be necassary?
Just thought I would throw this out for discussion, meanwhile I am waiting to get paid before I decide so if I find out more I will keep the thread alive.
