On the same bench, the same day, under the same conditions, my H-pump put out 687cc. Its peak injection pressure is about 150-200 bar higher than a P-pump, & its cam is a MUCH faster rate (meaning it reaches peak pressure much faster). It also has constant pressure valves that retain pressure in the line just below the pop pressure of the injector,;which reduces dribbling, & the haze associated with it.

Ah, that's pretty cool! You should be all set on fueling then. Quick injection event, paired with some higher pop pressure injectors, and being able to change timing should make that thing ridiculously snappy!
