I've heard that provided the NO2 is working properly. The only real killer of our engines is the instant spike of tq that happens as soon as the nitrous is activated. I only plan on running 100-125 shot max but I was curious about something. If I did two stages and have the first stage be like a 50 shot, the shock to the motor would be minimal. Then have the second stage be 75-100 shot. Wouldn't I actually get better performance this way. Especially if I'm using a total of a higher hp hit. Also would it help me keep traction a little better throughout the run instead of instantly getting 100+ hp slapped on. Is this feasable or just stick with one shot? If it's a good idea to run how would I go about doing it? FYI the car has about 110,000 miles on her.

 

I would not do a dual stage on a stock motor. Hit a single shot. A 150 shot would be the supposed safe limit. Provided you have proper; fuel system, timing retard, spark plugs, window switch, etc. Look at what other people have done with stock motors. You don't see too many dual stages on stock bottom ends.

 

I honestly don't think it would be worth the trouble of running a dual stage.
like the Rival said good fuel system, plugs, retard timing, maybe a lil race gas 125 - 150 single shot should be safe

 

I have read about people who make their n20 line longer than their fuel line (i think this is how they did it) from the solenoid to the plate (or nozzle or whatever), so the system comes on rich and is more of a gradual hit. Not sure if this is a safe practice or not. Seems to me you would also have to be careful to make sure you dont encounter any backfires or anything of that sort if you go overkill on the nitrous line length. Anybody tried this?

 

I agree with the others above that you should fine with a single stage shot, but with that being said I do run a two stage system on my car. I mainly do it for two reasons which are traction and to save my transmission. I run a 175 shot which is 75 out of the hole and then another 100 a few car links out. My buddy runs a 175 shot single stage on a car very similar to mine and he cuts 1.49 60' times with the left front wheel 6" in the air on 26X10 slicks which is great, but I don't think my transimission will take that. As I bring my drive train up to the task the second stage will get closer and closer to the first. It also works pretty good on the street where the traction is not as good as it is at the track. Thanks

 

That's what I'm talking about. Would it be more feasable from a traction and drivetrain strength issue? Or is it still not a big enough deal to worry about?

 

I definately don't think its required but I do kind of like it. On the street I run a 50 shot on the micro switch and then another 100 on a button and I only use it if I need it. That way my car still gets out of the hole good but it doesn't blow the tires away. I keep the NX two stage systems in stock because I do get a fair amount of requests for them but not nearly as many as I get for the single stage systems. Thanks

 

A Progressive timer is a beautiful thing

 

Dual stage is great! But certainly not a requirement. I did it for traction purposes mainly. But it's a lot easier on the engine and drivetrain as well. I also have the option of only running the first stage if I want to. I use RPM activated window switches for for both stages, as well as arming switches for both.

 

after using a progressive for 2 years,i would much rather go with the dual stage.
Progressives are great,but they beat the crap out of the solenoids.
a dual stage is an effective traction aid,cause i know hooking up with a 175 hit with my converter wasnt gonna happen.

 

I have a dual stage kit but just have on stage hooked up right now. As soon as I can hook up good on motor I will try the 175 shot that probably won't hook but i am running 3.42's with the high 2.52 first of a TH350. I am hoping it will hookup decntly but if not I plan on going 125/75=200shot. Which is what I planned on spraying anyways.

 

T/A LT1,thats not a high first gear,try hooking a 175 with a 3.06 first and a 3.73 gear.lol


sounds like a good setup

 

yeah, i agree, i like the idea of a two stage kit myself, i think the drivetrain will handle a larger shot that way. i do plan on changing pistons and i'm wondering how big i can go without running into fuel problems or risk busting a rod.

i'm thinking of a 75 shot from the hole and 150 shot after that.
if i have to i'll rig up a seperated dedicated fuel system for the nitrous with a seperate pump and race gas.
but the real question is how much with stock rods and crank handle?

 

Dual stage is the way to go when running large amounts (more than 200-250hp) of nitrous. Not worth the bother and cost for a 100-150 shot IMHO.
