So I guess it still has to have the fuel rails, etc installed.


Individual nozzles screw into each runner by the head.


Have you played around with different nozzle locations? There should be some power gain from evaporation but I don't know where the nozzle should be to optimize that.

After reading this I chose to leave the nozzles where they were. Puppy agreed.
Reading further about down nozzles in the heads that spray directly on the intake valve is interesting.



That’s on stack injection and I’m not sure I even believe that. I ran two flying toilets on a tunnel ram and every time I moved the nozzles up I made more power everywhere. Maybe, maybe because stack injection limits airflow moving the nozzles up may be a power loss. Maybe. But on a manifold like yours moving the nozzles up to the base of the plenum will make more power. If you lose some idle quality, increase the idle check pressure. I ended up at 12 or 14 PSI on the idle check with the nozzles up high and it idled as good as it did with the lower nozzle position.

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
