So I'm planning a direct port nitrous setup on my LQ9 swapped 84. The rings are already gaped for spray as per Hasting's spec. The plugs have a non-protruding ground strap and are two heat ranges colder than stock. The motor has a Summit cam, ported heads and a FAST 102mm intake on it. The whole thing is run by a Holley Terminator ECU and uses a flex fuel sensor so this will be sprayed while running E85. So this is my plan:

I want to run up to a 200 dry shot. This will be progressive. The Holley ECU has NPN PWM outputs that can pulse a solid state relay for progressive nitrous. I've played with nitrous oxide for years. But this is the first dry and the first progressive system I've ever worked with.

So after way too many hours reading I found that progressive nitrous works better with smaller solenoids. Could I use two of the smaller 150 hp shot size solenoids? One for bank 1 and the other for bank 2? Then use a trashcan style solenoid to feed them both for extra safety. The trashcan solenoid wouldn't be progressive. It would just open when the ECU started to pulse the other two. Would that work? Am I over thinking it?

The nice thing about a system like this is the plumbing would be a lot easier than a traditional fogger because there are no fuel lines on this. What do you guys think? Any advice? Anything I'm missing?
