I am probably going to get stage 3, and I am wondering what I need to run nitrous on it? The ecu is supposed to adjust timing and fuel for it on its own, but I'm wondering how it knows that the nitrous is on? Obviously I need a bottle, lines, and a nozzle ... but isnt the stage 3 supposed to act as a window switch if it has control over the shot? I was told it starts spraying at wot over 3000rpm, and cuts it 500rpm before your set redline, but do you need the actual dry shot control chip from the full kit? I just want to know if I'm gonna have to buy a full kit or if I save alot of money off my set-up by just ordering the nessesary parts if the ecu can control everything itself and doesnt need a n2o controller or a window switch or tps swith.

I'd rather not hear speculation as to rather it should or shouldnt; I would like to hear from someone who actually has stage 3 and is running a dry shot with it. As allways I apreciate your answers and support, I'm just hear to learn.

The PCM controls everything. All you need is a Dry 50shot kit. The PCM will give you a 12vdc out, which goes to the Nitrous plunger relay. The PCM will 'spray' from ~3500rpms to ~6000rpms or so.

download the instruction sheet, it will answer mostly all your questions.

he went 20 bottles on his car which is idk how many runs and he ran the bottle pressure really high. i've gone through 4 bottles on my 5th. i've told you in pm's. i personally think just leave exactly what you have and add a wet kit is your best bet.

Hey CBodnar, how do you like the spray so far? I havn't been on here for a while, I bought a GTO and kinda left the balt to the side.

CBodnar

it's fun. i just drive around with gm stg2, airbox, 2.8, when ever i see a car or a car asks me to race i just flip one switch on that turns red to the left of my steering wheel (near the trunk button in there) then i go in front of my shifter an pull up the 2 cup holders and under there i have my button. click the magical button and it gives me a little bit more speed. also when you click it you get full boost so much faster. it is like adding on a whole stage 2 kit on. for only paying $285 for the nos sniper kit new on ebay you can't go wrong.

I hear ya on the boosting, I'm hitting ~21psi, I think I need a new gauge to know exactly how much I'm boosting.

everyone tells me there stock dp gets clogged and the have had problems with it. i am 23k miles in and no problems with anything other than my clutch slipped once on the dyno. other than that on the street it is fine. maybe it is because i drive it hard most of the time he has no time to get clogged lol. since i bought my car right out of the dealership i was driving it hard pushing it to the limits on regular gas. then again i am also a firm believe of regular gas is fine to put in our car. the only reason to put v-power in or something is if your engine is pinging. otherwise if there is no ping your car does not require premium fuel.

go call up a parts store and ask them. also for people who buy royal purple. go to a place to buy oil and check on the back of all them where the oil comes from. it comes from all the same place. royal purple doesn't give you more power. they just have a bunch of people selling there product good saying it does something but it doesn't. i don't think people realize that but whatever. most the people who know the truth don't try to argue it because fact is majority of people on here are 16-20. most of them believe what they see and hear and believe oil can make power. wrong. also regular vs. v-power. it is the same thing. you do not get any extra power. i've done both and maybe only thing is it can make the engine last longer? not sure. otherwise regular is fine to put in the car unless the car pings. you can call me crazy but these are facts. just like mobile-1 paid GM a lot of money to put mobile-1 on there oil caps for people who buy the car to think mobile-1 is the only oil you can put in the car.

You mean you spray on 87 octane? Wow, speechless. I've been spraying since 19k, and its on 34k now, with no problems. I have a stock catless DP, and my OG stock pipe. When I removed my stock one, all I saw was a bunch of white residue from the spray. I changed out my clutch 4 months ago, only because when I ran it hard, the clutch felt soggy. To my surprise, the stock clutch and the new clutch looked identical. The only thing that realy needed replacement was the pressure plate and flywheel. Our cobalts use the disposable type that can't be resurfaced. I did keep the old clutch cause its still in good shape.
As far as oil, well, I use synthetic. So are you using conventional? True that most people are 16-20, after all this is a car made for the younger crowd. In to GTO forums, the majority of the commnunity are older than that.
I'm trying to make time to get back on the dyno. I want to see how much power the CA header and Fidanza added. Hopefully I can get good number like yours.

CBodnar

no. i use higher octane now. when i was stock i put regular in it. no point. i raced my friend he put v-power in his we switched cars mine was always the one that was in front and faster for some reason stock for stock. both 07's and both brand new off the lot. now i put v-power in it and use fully synthetic oil, but i don't care what brand it is. all of them come from the same place look right on the back of the damn oil container. lol

i was like most the people on here. i was about to buy royal purple then my dad said wtf u gotta be on crack. then proved me wrong in every way and now i realize it is all the same. fully synthetic = fully synthetic. all are the same. all come from the same place.

also i am sorta happy i didn't go stage 3 cause i would of spent more money. also your dyno numbers 274 is that whp? and 306torque?

that sounds better. Yeah, those are my dyno numbers. It made that on the 4th run. I'm scheduling in a new dyno run, fresh in the morning too see how good the numbers are now with the flywheel and shorty header.

The best thing about GMPP stage 3 is that if for any reason it detects knock or any malfunction, it automatically stops spraying. Plus it has a tune for 100 octane, which you can switch on/off and you can set your own rpm redline. What sucks is no AC.

CBodnar

u can fix the no a/c though. i think i put the links above. if not i can post them up again

Maetrix

Post the links, man!

This is the only hesitation that I have about Stage 3.

My car has to last, that's the only reason that I have against custom
tuning and pushing the envelope in pursuit of unholy horsepower.

I'll take the rish tune of the stage 3, and sacrifice a little hp for a
little reliability.

I understand it's all relative, but it helps me sleep a little better at night so I'm gonne
roll with it!

So heres a question... On the stage 3 setup, you don't have to spray before the MAF? The pcm already automatically detects?

NJBLUESS

Correct, after the MAF sensor.

hey my best time is 13.79@104 with the 50shot where should i be?

So if I wanted to be safer on my engine and spray let say... a 40 shot, the ecu isnt gonna know the difference, and add fuel for a 50 shot? Basically I'd run a little bit more rich and lose a little power, but be on the safer side, since a dry shot on 42.5lb injectors and a 2.9 or 3.0 is kinda pushing the injectors. Also cool that it stops spraying if it detects knock, maybe thats the reason roelss only dyno'ed 274whp 306wtq on a 50 shot? If he leaned out up top and it knocked, it wouldve stopped spraying... the lack of problems down low would account for why only his hp was abnormally low, and the tq was about normal?

bulls'ss

hold on now im not sure what you all find so funny. im just wondering how much a 50 shot would help. i have 2.6 pulley/42lbinjectors/header/ full exhaust/intake and run consistant 13.79 and im trying to decide to spray or not.

CBodnar

i think personally this goes out to a lot of people with big hp. you need to de-mod your car and learn how to drive it and get at least a 14.5 before you upgrade. if your running 13.8 with your mod

Kibosh3

something doesnt seem right...

i have a smaller pulley than you, as well as the boost juice and i only see about 16 psi at wot....

check ur cat just to be safe, considering that your richness (if you have any) may be causing a clog....hence backpressure and higher psi...

just a fair warning

BCobaltSS

13.79 on 50 shot is not good. Should be in the 12's

Oops sorry should have read that better . Yea with a 50 shot you should be into the 12's
