V8 @ 1000 rpm = .060 sec/rev = .120 sec per 4cycles or .030 (30ms) per
intake event (approx)

Duty cycle = (pulse width/cycle)/(time/cycle)

We can easily calculate DC from PW and RPM. (assuming 1 pulse per 4
cycles)
DC = PW/(120/rpm) or PW*RPM/120

V8 @ 7000 rpm = .00857 sec/rev = .0171 sec/4c or .004286 (4.29ms) sec /
intake event

How big of an injector can do that???? ( I need 120 pounders!)

I think we need PW......  Regards  Tom
