My hemi heads have been drilled and tapped for down nozzles,used fuel heads.While reading post on rotary injectors I noticed few comment about nozzle placement.Most sem to think dry runner and port aided in increase air.Having read few things about amount of fuel in intake charge occupying area instead of air it makes good sense.
Is there any gain by using down nozzle location.Since its NA motor seems I could just plumb regular nozzles in that location.Not something I want to do from start,figure get good baseline tuneup then try few things and this could be one thing to add to list.
