Use 80% (.8) for duty cycle.
To solve for hp re-arrange the equation to:
hp = (lb/hr * num cyl * duty cycle)/(BSFC)
Forced induction = 640 hp
NA = 768 hp
Someone check my math

Thanks guys, I was planning on running a D1sc with the intent on maxing it out down the road. I was also mulling over the whole E-85 idea as well. I know you need a bigger fuel system as the E-85 requires more fuel. I'll probably end up with a dual racetronix set up from Nasty so I know the pump will be plenty goood. Would my 60# Motrons hold up to 700rwhp with E-85???

regulator?
what was base fuel pressure set at?
stock 58psi?

Meth changes the equation, and a RRFPR helps.
Theory (math) and reality don't always mesh. I'm sure they are being used in much higher HP applications. This equation is a good place to start. If you can get more out of them, nothing wrong with that.

Okay, so it looks like 60# injectors should hold up to an 700 rwhp motor which is where I want to be for now. But the new question is can they hold that kind of power level with E85?
