as I posted before, rising rate reg'r, bleed off vac signal with orifices to get about 1:1 ratio, use just rpm switch and cheap elec shut-off valve to close vent for enrichment above the rpm set point. Progressive enrichment with boost above set point ... max at high boost, none at zero boost.
advantage over 5th inj'r is balanced enrichment all cyl's. With trent set at 2.5 bar at zero boost and 1:1 with bleed, and say 26# inj's, you get:
11% more at wot 'till amm hits limit, mabe 4500 rpm set point
39% more fuel above trip at 20 psi boost
35% more fuel above trip at 15 psi boost
with 30# inj's, same type numbers are:
28%
60%
56%
