I have looked at this injector as well

Per Kurt

Here's how you calculate proper injector size to get you at 80% duty cycle;

Expected max horsepower x 1.2 x .5 for n/a ( .65 for boost) divided by the number of cylinders.

Example for 800 n/a : 800 X 1.2 = 960 X .5 = 480/8 = 60 so you would need a 60 lb/hr injector for an 800 hp n/a engine.
