Why not a progressive controller single stage?
Why not a progressive controller single stage? Other than for hole shot drag racing, why do so many street rod folks go with the 2 and 3 stage setups instead of a progressively controlled single Direct Port setup? I don't know much about nitrous, in general. It just seems a lot of people like the 2nd stage to kick on hard when the 1st stage begins to level out at their peak torque and start to fall. Wouldn't it be better to pull progressively hard through the entire safe-sprayable RPM range (3000 rpm+)?
I guess my point being that the cost of a nice 100-500 Direct Port setup would be as cheap or cheaper than buying 2 or three kits ... tuning costs would also be cheaper, wouldn't they? And wouldn't there be less chance for failure and destroying your motor?
Maybe it's the danger of an injector failing???

Until recently progressive controllers did not have the ability to run in an RPM based mode, they could only run based on time so having a two stage kit gave the user the ability to have more control over the kit.
Having two kits also allows you to spray different amounts of nitrous. ex. If you are going to race a ricer you might only need a 75 shot vs. if you had a race setup with another f-body you might want to spray 150 vs. if you had a race with a track only car you could spray both kits and end up with a 225 shot
Another reason is if you setup one stage as dry you can actually tune the car to go into a "nitrous tune" when you spray the first stage so it will pull timing, add fuel and things like that.
Those are just a few things I thought of off the top of my head I'm sure someone else will have some more input.

Another reason is amount of money need at one time.I bought my basic TNT kit used and have been adding the extras as time goes on.Now the kit is pretty complete and even has a few extra goodies (Nitro Daves plate and FJO controller). Maybe another 6 months from now I will add a basic dry kit and buy the extras slowly as my budget affords.
Trust me I would love to have a DP but the funds where not there for me to pay out one big lump sum.

and of corse that bling thing, but back then it was called Ego. lol
With the new controllers on the market people are realising the potential to have big power, controll that power, and with just a simple clean install.

on my budget setup I am using one big *** noid for the dry and the NX/FJO dual stage mini controller. I will only use one stage. Even though it can control 2. Atleast for now.
So if you want one good stage and have it progressievely controled....nothing wrong with that at all.

It all makes sense. Thanks for all the insight. I was looking at a $600+ progressive controller for a 100-500 DP setup. Is that about what I should be paying for one? I'll have NLP order the DP setup and maybe finance it ... since my 12-bolt is costing me a bulk amount of cash. This way, I can make payments to them and have a nice DP setup to go with it ... without it costing me too much at once. The cleaner the install, the better, so, that's one of many reasons I'm leaning towards a progressively controlled setup.
Maybe this will make sense ... maybe it won't: I think this type setup will be better/safer because at 2,500 rpm, I can start to spray about 75 (instead of waiting 'til 3,000 to spray more all-at-once) and up-the-spray through the rpm range so the full spray (maybe 200-250) will be at the highest rpm before shifting gears. I believe it will be a lot easier on the powertrain and internals and provide a nice, steady, increasing pull ... soas not to break momentum of the forward movement of the car ... with little room for driver error ... as opposed to other type setups.
Anybody think this makse sense? Or, is this not the desired outcome one would reasonably want to achieve with a nitrous setup?
