For you information, i have edelbrock perf RPM head
with E303 cam and the weak cobra intake. My fuel
pressure is at 38 PSI with #30 injectors. I did the fastest
quarter mile at that pressure.
When i had the # 24 injector the car was faster when
the FPR was at its maximum (65-70 PSI).
I think the optimum gas pressure vary a lot from car to
car. The difference could come from different mass air,
computer, compression etc I m just guessing correct me if
i am wrong.
