I got my 12a half bridge port started today!!! I cant figure out my fuel though. On my fpr gauge, it says im only pushing 3 lbs. of pressure. I adjusted my holley fpr and it goes lower, but wont go any higher. I have a carter fuel pump on there too. What are the carter fuel pumps rated at? I am running a holley 465cfm too. should i get a new pump. Any suggestions?

 

they will do 7psi. donot know that the flow raiting is though.

your regulator may only go to three as well.. i know that holew makes two, donot remember where the split is though... one is like 0-3 (or maybe 4) and the other is that to , oh lets say eight.. (i am pulling these numbers out of the top of my head, so donot quote me on anything)

 

oh, and ... what do you think of the port so far?

 

I dont want to get on it though until I get it all tuned out. Ill let you guys know though. Hopefully this thursday I can go to a shop and get it dynoed, if nothing falls apart.lol

 

I answered your question on the other thread.

BTW, flow rating on the Carter Street/Race that I have is 7psi@92gph. That should be shitloads of fuel, I can't imagine you needing more than that.

The holley FPR's are 1-4psi, and 4.5-9psi.

 

i obviously have the wrong fpr on
