Pressure regulator

[JMo60]

well since i have installed my 3400, i started thinkin..
I am using the 3100 fuel rail and injectors... if i used the 3400 fuel pressure regulator on the 3100 rail, how much more pressure will this provide? Do you guys think it is necessary to raise the fuel pressure with runnin a 3400 with milzy stg 1 cam? just wanted to see what everyone thought, lets hear some input

I would put an adjustable FPR on it. But for the most part you need to watch the knock retart for that cam.

my hybrid has a crane 272 cam and its running rich with 3100 injectors and a 97 fpr. i am gonna go back to 3.1 injectors

i forget the cam specs on the stage one but i think mines a lil more rough.

just something to look at

You *should* be good with the 3.1 injectors syn. I'm not sure how the cam will affect your a/f but 3.1 injectors should be what you need to be running.
