is there such an animal at 43.5 fuel press. or will they be 60# injectors with more base pressure.

im asking because i am planing on running a return fuel system with a set base pressure, then 1-1 rise with boost.

i need to support approx. 1100 rwhp. "edit." 800 rwhp? Im asking questions because i dont know.

80's are wayyyyyy too small for 1100rwhp.

thanks for the reply, so for what im doing i would set base press at 43.5 and let the regulator 1-1 with boost? i assume the 58 psi is stock rail pressure with out a return regulator.

I will start my build thread friday. this is my first LS build, been modding cars for 25 years,

Even thoe its 1-1 you might not get 15 psi increase in fuel pressure with 15 lbs boost.
Idealy at max power you want to be around 80% duty cycle. So work it till you get that and your base pressure is what it is.

that helps, so, give it what it wants.

As an FYI... the 80# Mototrons do flow 80 at 43.5psi.

And yes they will support 800rwhp.
