Fuel Rail

[BloodBath]

I just ordered some DW 1000cc injectors. I am curious what the horsepower limitations of the stock side feed fuel rail are on an RB25DET.

What is the most power seen on a stock fuel rail?

At what power level does the fuel rail become the restrictive point?

Thanks in advance guys.

what fuel?

[R31Nismoid]

400rwkw no problem, seen over that as well.

I got the 1000's just incase I want to run e85. But probably 91 pump and race gas q16 c16 or something. Glad the stock rail is t restrictive.

91 you would be better off 98 unless your not in aus and can't get hold of it

seening it says he is in the USA i would assume he cant

[JonnoHR31]

US 91 is different to aus 91.

i've also been curious as to where the standard 25 rail becomes a restriction. i have 1000cc side feeds aswell and was considering running dual feeds with the FPR before the rail when the time comes for e85 if the standard rail isnt up to it.

I'm on my phone so does not tell me where he is with the rail it's really not a restriction I believe it's only the fpr that becomes one

Fpr still ok at 420kw unless its faulty

Thanks for the heads up. That's definitely good news. That's 500 plus horsepower. I think I'll be good.
