injectors and fuel pump?? Recipe to fueling 1000rwhp?
Right now im shooting for 800rwhp on a 370 twin turbo build of mine. But I want to have some headroom hence the 1000rwhp.
I was going to go with 80# high impedence injectors, 450 walbro fuel pump, Aeromotive 13129 Fuel Pressure Regulator EFI Bypass 30-70 PSI Adjustable -6 AN, and of course the fuel rails I already bought. I will be running e85
But im thinking this may not be enough. Thoughts?

I’m not well versed on this but was recently doing research on this subject for the same reasons you are with similar goal in mind.
My research concluded that 1gal of gasoline not e85 weights 5.994lbs using a bsfc of .65 it come out to be 9.22 hp per hour 5.994/.65=9.22 so 1gal supports 9hp per hour. 1000hp/9hp=111gph needed 111gph=420lph. It’s my understanding that e85 requires approx 30%more fuel. So 420 * .3= 126 add that back to the 420. 420+126=546lph.
Hopefully someone more versed in the subject will chime in.
But that was my interpretation of my research. I’ll try to dig up the old threads that I referenced for my research and post a link.

Some sources say 1gal of gas weighs 6.3 so if you use that number it’s comes out to be 397lph for gas to support 1000hp. Add in the 30% for e85 and it comes out to 519lph so whichever number you use is going to be close to the same. Personally I would use the 5.994 or 6 even for a safety margin

I did decide to go with Bosch 210s, fuel cell, and a Holley 12-1800 dominator
I think this will be plenty for me
