A post below (Nozzles In Hat) twigged a memory/thought in my brain. The Enforcer port fuel nozzles. Did not want to side track that earlier thread, so here we are with its own. Reportedly 50+ Hp back to back dyno gain over standard port MFI nozzles. Internal mixing conical atomizing (industrial style) nozzles is basically what they are. Excellent atomization at high differential fuel pressures. Questionable mixing at less differential pressures. Subject to the square of the pressure differential drop in terms of mass flow. Did they not work out, or were they just not pursued out of complexity, or did they just get abandoned because they were unfamiliar? Sounds like they possibly might have had had great potential versus the old standard MFI "thumb over the garden hose approach" nozzles, but perhaps there were other complications people found along the way that thwarted their pursuit? Curious to hear thoughts, and just thinking out loud........ Thanks.
