Six pack to The summit

please state your goal for the system. Six pac intakes are short runner, single plane. Any mix in the plenum gets delivered in some percentage to each port. How much depends on where the mix comes from at that moment. Distribution during tip in of the outboards is spotty but it clears quickly as they come on board. The old system was a cheater solenoid which maxed out at 250hp iirc. That was old spray at tech, and I’d wager the NX plate is much better. But still limited by volume of a single plate. Hence the comment about port injection. I ran plates for a few years.
My intent is to determine the best type of nitrous system to build for a six-pack application with a TA manifold without hacking up the manifold .You mentioned you ran plates previously did you find that some plugs ran hotter than others or did it seem to be well balanced with your system.
