The reason is this - the open time of the injectors
(and therefore the amount of fuel released per injection ) IS NOT
dependent on the RPM but the loading of the engine (manifold pressure or air
flow rate is normally used to determine this). All the rpm does is
determine how many times the injectors fire per unit time (and over
simplification but essentially correct). The injectors will of course fire
more often at higher rpms (but will not necessarily stay open longer-depends on
manifold pressure)
That was
the key point that I was missing. HP is a TIME based
measurement, so you don't have to deliver the full load of fuel in just one
intake cycle. Makes perfect sense now.
Thanks,
Rusty
