Hey guy's can you tell me if 38lb. injectors will be good enough to support about 450 rwhp. I will have a 255 intake fuel pump and regulator.
thanx in advance.

What fuel pressure? 450RWHP of boost, spray or NA?

It was 450 of boost. Just got a responce from Byron and he said they will work. They are good to about 480-500 rwhp. Thanx for your reply.

You probably forgot to mention you only have a 255 intank pump. I'm not a fan of those lucas 38's myself.

Not intank. You can either get a walbro inline pump, or sump your tank and go with an external one like an Aeromotive or Weldon. The problem with 'smaller' injectors is that they require higher fuel pressures.... your pump can't pump as much fuel under higher pressures... basicly those 38 lbs injectors at 65 psi are making your 255 pump flow a less.... you can find a fuel pressure vs flow chart for the Walbro 255lph if you search for it online.
