Im guessing an EFI system.


yes thats what I figured, but if it's not needed why run that much pressure?




I am currently running a carb but EFI is in the near future. My plan is to run ford style injectors which I have that are rated at 43psi. My EFI system is GM so my pressure will be at 58psi like a standard GM system. It will have a variable pump control so it will not be at 58 all the time but under boost it will be 58 or more. This also lets me run a smaller injector too. I can run injectors rated at 42lbs @43psi @80%duty cycle. At 58 psi they will be in the 50lb range @ 80% duty cycle and maybe higher @ 95%. My intention is to balance the injector sizing so that I can get better economy at cruise and idle and still have enough for the boost at WOT.
