Quick FPR question: Diagram Inside

[CrUZida]

Yeah, otherwise your fuel pump could start dying, which will cost a lot more in repairs. (unless its like the uber bosch pump?)

Perhaps its worth even going to a bigger injector again?
Or converting to topfeed if you have the sidefeed 3SGTE rail?

Depends how much power you want to get from her.

I want another 25awkw on my 175kw/ 318nm it has atm. I thought a reg would get me over the line just..ohh well, thats what happens when you try and cut corners..

pump is a walbro 255lph.

rail is standard side feed gen2.

[CrUZida]

Walbro's struggle seriously over 60psi, unless you get the hi-output version of it, which most aren't.

42psi base + 18psi boost = 60psi fuel pressure.

[Draven]

yeah, a 1:1 is not a rising rate, it maintains fuel pressure with increasing boost, but does not increase it.
umm, my mind is fading from no sleep - someone else explain this coherently please

Why would someone be using a RRFPR on a turbo motor?
I thought only cheap people used them on NA-T conversions coz they won't fork out for an ECU

Cheap people use it on turbo engines to fit a fuel cut defender (effectively clamping the injector output) and then refill the fueling requirements with the RRFPR.
Very dodgy, but I guess it must work adequately enough for people to do it.

im hitting max injectors on 6psi so have got the rr to wind the fuel pressure up a few psi.


or to make the injectors big and strong ive used a rr to give me a bit more out of the injectors.
