Eight 100 lb/hr injectors is a ton of fuel. My 514 has 66 lb/hr injectors and that engine makes 900 hp. Eight 100 lb/hr injectors is enough for 1600+ hp.

It might work okay if they have some sort of injector shut off at low RPM. Maybe the software turns off 4 of the injectors below 3000 rpm or something like that?

My 514 uses 340 lbs/hour to make 900 hp so I could get by with half the fuel flow that Holley is putting in that 4500 Stealth. They are really thinking big with that setup!
