Sard FPR

Postby AE82 FXGT » Tue Jan 30, 2007 7:14 pm

Hey guys,

I'm checking out the average prices for a genuine Sard fuel pressure regulator.

Are these adjustable at all?
Or are they just boost referenced?
And would a fpr make that much of a difference if you're running the factory ECU?

AS I see it the ECU would compensate for the extra pressure by altering the injector phasing etc.

they're adjustable, i think i paid heaps for mine cos i wanted it right then, think they go for between 250 and 300.

mine made a difference, injectors were maxed out so bumped up the fuel pressure so more fuel at same duty cycle (at least thats the theory? car doesn't lean out anymore so i assume its working)

So did you buy a gauge to know what the fuel pressure was at?
And duty cycle was the words I was after not phasing...
