3 Stages-Why?

We can set your current system up to run both stages through the plate. You will move your jets into a custom machined "Y" and then run a single line to the plate. Each stage will feed one side of the "Y".
Doing this will save you money over the NX MAF ends and give you the same or better results.
I am running a single stage and a progressive on mine. I typically have full power within 1 sec. With a pulse frequency of 15 they will cycle less than 12-15 times each run...most runs were run with a .5-.7 second ramp time. I have had the progressive on the car for 2-3 years with a set of 5yr old NX solenoids. Last time they were inspected they were still in excellent condition. If you are going to use a progressive you need to make sure the solenoids are designed with them in mind.
A progressive is designed to be used for traction control not horsepower control. I see alot of people that want to jet their kit for 300HP, but set the progressive to 50%. They then think they are running a 150 shot, but they are running a 300 shot 50% of the time

Race cars use 3 stages for reason listed.
Street cars run 3 stages becuase they want to show off. LOL
And for 3 stages you only need 2 sets of solenoids.
EXP. 1st set 100 2nd set 200
Launch on stage 1, the Turning stage 2 on turns stage 1 off, then you have a button to run stage 1 back on.
Simple set up and does not cost a bunch.
Another thing is applied HP.
Your car will only 60ft SO fast so by applying more power then is need to that point is a waste and most of the time hurts parts.

If you plan on going bigger than 2-250 I would highly suggest going direct port, as this will remove any distribution issues you might see. Or convert to a single plane manifold and go with a carb style plate or spray bars in the intake.
This is the route I am going....

A ton of LT1 guys break spark plugs and pistons on shots that large through the TB. Too much nitrous gets pulled into some of the cylinders and too little into others. Do a search for it. Lots of broken #7 parts.

Edit: Oh yea, that's a trick way to run a 3 stage.

I have been running a 150-200 progressively controled single stage. On a very well prepped track I can hit the whole thing out of the gate with no need to progress the hit. This is how I use the progressive controller.
If the car is dead hooking NA, first pass will be 100% activation. If the car spins on the hit, I will back the start % down according to how bad it spins. Lets assume slight wheel spin that quits soon after launch. Start % is set to 75% ramping to 100% over 1 sec. Now if the car is spinning on motor I will add a delay to the nitrous activation, say .5 Sec starting at 25% and ramping to 100% over 1 sec. If the car spins when the nitrous comes in I increase the delay or lower the start %, if it spins down track I increase the ramp time.
I have never had the ramp time set for longer the 2 sec. I usually am all in by the 60'. I do not see an issue with having the 300 shot at 100% by then either since I rarely have to progress the 200 more then .5-.7 sec, even on a marginal track. The sooner you can bring the nitrous in the faster you can make it to the finish line.
there is no need to progress for 10.8 seconds.
A progressive set to 50% means the solenoids are open 50% of the time...75% is open 75% of the time. You cannot open a solenoid halfway, they are either open or closed. Its just like filipping the master arm swith on and off during a run.

Sorry Ray, but it makes no sense what your saying. You make it sound like percent equals full hit, 75% out of the hole means I am still getting the full 300rwhp hit 75% of the time, what the hell would I run a progresser for, it's not going to help if I am still getting the massive torque spike which I am trying to avoid. It's just not adding up here, maybe this is why I hate the progressives. It's pulsing at a differnt rate, so as to not let all the nitrous in.
By pulsing the solenoids you will reduce the total power the car makes. But you are looking at the progressive as a HP controlling device. Pulsing the solenoids will reduce the total power you make, but it is not a direct relation between HP and the % you are setting the controller.
50% of a 300 shot is not a 150 shot..this is the point I am trying to make.
For your application stages work better. Because you are looking for HP control. Progressives are better for the guy that needs to control the nitrous for traction purposes.

Anybody running a progressive for launching and then multi stages as run progresses?
