Stacking multiple boxes from same Mfg.

[Jeff Clark]

Let me qualify this by saying that I don't plan on doing this, but here's the story.



I stopped by a friend's shop yesterday and he was installing a Edge box on a Ford. He was telling me about a guy he knows with an 03 or 04 Dodge that wants to stack 4 boxes of the same brand. His (this guy, not my friend) theory is that if one gives you X hp, then 4 gives you 4X hp. I don't think it works that way and I say the guy is wasting his money. I figure one of two things will happen. Either he will have only as much added hp as one box would give him and he can run around bragging that he has more than he really does, or the engine will blow sky-high the second he fires it. I told my friend to let this guy know that none of this will work without other fuel system and turbo mods and he says the guy plans to address those areas, but I think he's nuts stacking that many boxes.



Anyone want to weigh in on this?

Yea that might be too much. More is not always better, but what ever makes him feel good

Well keep in mind how a EZ pressure box works



It lies to the ECM and the ECM then add pressure to meet the factory requirement



So if the boxes lie to eachother, I think you will only get the power of one



If they are duration boxes, I would think they WOULD add up, but the duration would only net high temps and smoke, no power i bet
