fuel pressure regulator
hi guys...need some opinion here..
i got an escort cosworth that has been fitted with 803 green injector, -31 actuator, and fuel pump. I'm gonna up the boost to approx 1,3bar (19psi).
Do you think I need to change the standard 3,5 Bar fuel pressure regulator into a 4 BAR? Or just use the standard 3,5Bar?
Thank's guys...

No mate a standard FPR is well upto the job.
As long as it's set to 3 Bar with the Vacuum pipe on and 3.5 bar with the vacuum pipe off it will be ok.
A standard frp will have a raising rate of 1:1 so for every 1psi of boost you run the frp will raise the fuel by 1psi.
Which is exactly what you want.

And planning to dyno tune it and set the boost at 1,3 Bar ( 19psi ).
So the standard FPR will do the job then?
And is the standard FPR is a 3 BAR or 3,5 BAR ? I thought it's 3,5 BAR?
Thanks again...
Std reg is 3.5 bar with no depression on the reference pipe.
The std one is fine for well over 500bhp, the only issue you have eventually with them is that they dont flow enough fuel if you run 2 pumps etc for big power fuel supply, then you end up with too much pressure in the line as the reg cannot bypass enough.
