I have a modified NOS 05177 kit that I have been running in my car. When I bought the kit, I didn't have the instructions, but I was able install it with no real problems. I also did a progressive controller, so the power addition could be seamless.

I was shooting for 100 rwhp, so I tried a .052 jet. I didn't meet my goal so I drilled the jet to a .054. I gained 100 early in the rpm range, but netted only 75 rwhp at peak. I settled with that as I didn't want to be greedy.

Fast forward a year later, and I now want more.....

I stepped up to a .062 jet and honestly picked up nothing at all.

The bottle pressure has been kept at 900-1000 and was freshly filled when on the dyno. Also the inline filter is clear and the solenoids are functioning.

I was thinking that maybe I had found the limit of the -3an lines used on some parts of this kit, but I have read that -3an is .138, more than double the size of my .062 jet.

Today I downloaded the instructions for the kit I have, and find it only comes with jets to 100hp (not wheel hp I'm sure). I think this kit may be limited to only flow 100 hp.

Here is a diagram of how my kit is installed:



I have the solenoids installed exactly as the diagram shows. I believe that dual solenoids are a good idea when running a progressive controller as if one fails and sticks open, it's very unlikely the other one will. I use it as a safety measure.

I am beginning to believe that the solenoids together may be the problem. I have understood the a 16020 solenoid will flow 150hp wide open. I also figure that would be enough for at least 135ish rwhp.

So, does anyone have any experience running dual solenoids like this? Does the two of them combined create a flow issue? Could it actually be the -3an line?

Any help would be greatly appreciated.

Some important details are left out ,like what vehicle,mods,and what injectors.What first comes to mind is injectors not able to deliver.Any time you run injectors over 85% duty cycle you're starting to work them, this is another case where a wide band becomes important

I run that kit. The most I ever got out of it using the noids that come with the kit was 135 rwhp (cam only, 42# injectors, full exhaust M6 at that time).

Where is the rest of the diagram you are not showing? You also say that you tried a 100 hp jet which you say is a .052, that kit says it's a .032. You are using the wet jetting. Did you convert the kit?

It is a head cam car that is properly equipped to handle and deliver the power. The shortcoming is not in the combo on the car, I has to be in the kit. Duty cycle is around 65%.

I am only running as the diagram shows. It is somewhat concealed so I didnt want to try to hide the rest of it. I am running it dry.

I'm hope someone with experience in nitrous flow might speak up and point out the limitations.

Some time ago I ran a kit in another car with a single nozzle and made power like it was supposed to. The kit used the same solenoid, but did NOT use two of them.

The used with dual nozzles runs dual .032 jets to make 100 hp, not one like I'm running.

I used http://www.robietherobot.com/nitrousjetcalculator.htm

And various other sites and threads to calculate jet sizes for my power goal s

I think the second solenoid is a restriction in the line. The orifice in those solenoids Is .078. When you put 2 of them, even though they have a bigger orifice than the jet, it's still in the way. I say ditch them and put a single .118 solenoid in there and go from there. What are you using to provide more fuel?

It's a dry shot and we use an IAT manipulator to add fuel

Removing one of the solenoids gained APPX 40rwhp.

Replace the noid, that kit uses 2 noids because they are prone to leaking under pressure... I would not run just one on its own
