o wasnt aware srt's had HO mode.

ya stage 3 is a good option if u look at it that way. i guess its preference. what i dont get though is why there isnt a package just to buy stage 3. it says u have to buy stage 2 first then go to 3. my understanding is that stage 3 only uses the injectors and belt. correct me if im wrong.

yes, yes it is. if u think nitrous isnt, ask urself what other company offers a stage kit that inludes nitrous??? nitrous is a great way to make power no doubt, but its stuff like that, that people are going to say "i can have warrenty with nitrious!" that are going to lure in sales for stage 3

 

I disagree my man. I think those modes rock and are a great idea.

Ford has offered a nitrous "stage" kit before. It was for the focus I believe.

You will need the belt and the injectors, along with the hub for the pulley.

 

the mods rock and are a great idea im not saying that they arent. just saying its not common.

and wow learn something new everyday. cant believe ford offered nitrious stage kit as well. im glad u know ur stuff. helps me

 

Hey fnfast, when you mean relearn do you mean the thing where you have to tap the gas and turn the key on and off?

 

I don't believe so. Just the unplugging of the terminal for 10 minutes.

For some reason or the other my cars security system didn't like the pcm at first and the security ssytem shut the car completely off...wouldn't start or anything. GM had to "relearn" everything in order to get it to work properly.

Didn't take too long and works fine now though.

 

I was looking at the PSM and it seem like it only comes out a certain way. Is there any special way to pull the PCM out a certain tab or screw that you have to push down or pull out .

nevermind just got it plugged in now it's time to play

Well just got back from testing it out. It is pretty to cool to see the tach go to 7250rpm . I did not take it past that and most of the time I shifted out at 7000rpm any way . I was not able to try out the 100 octane mode yet becasue I have 3/4 tank left of 93 octane. Once that is through then there is a place right down the street that sells the 100 oct unleaded at 5.39 per gallon. I will put in a about 5gallons in to toy with the 100 octane mode.

As far as how it drives- the tune seems to be more agressive . The shifting seems smoother and there does not seem to be any bog between 1st and second .I can tell its dumping more fuel becasue the I can hear more popping coming from the exhaust when I down shift . more than normal that is. When I nailed it in first and shifted out at 7000rpm it will pop. Go over to the war storie section to hear how my run in with a convertible brand new porsche was. It was brand bew because it had a dealer plate on it and no it was not used.

I'll check back in to let you guys know how the 100 octane feels.

Man it's like the car woke up even more then when the stage 2 was put in .

 

FNFAST- What nitrous company did you use. was there one specific kit for the cobalt SS/SC ? Can you take some photos of how it hooks up to the motor. Finally did you get that part number for the GM harness it calls for in the Stage 3 hook up?


Thanks

 

He used a dynotune kit. heres the link for it.

look for 4 & 6 cylinder dry kit.

 

Not bad for $269 i think this will be the upgrade I put in the car this time next year when the warranty is up

 

Yep, not bad at all, i'll be getting it after my header and downpipe.

 

I sent you an PM with contact information and my email for pics coby

Congrats again on the purchase, sounds like it is working for you.

PS if you deal with dyno tune ask for Dan and tell him Jason sent over

An under the hood shot of my car is on their home page

Hey fnfast did you ever get that part number for bcobaltss, because I think I'm going to need it to?

 

FNFAST- I sent you a PM back .
Too bad on the web site (http://www.dynotunenitrous.com/store...efault.asp)the photo is so far away to see how it is hooked up.
Did you ever get dynoed with just the 100octane mode and not with the juice to see wha the number was?

 

No but the HO mode gave me roughly 8 horse at the dyno when using it with nitrous

I gave him the number to call for the part number...figured he could explain what he was looking for better than I although I think I nkow what you are looking for. He should be able to get the part number for you guys...if for some reason he can't I will call and get it.

 

Stage 3 100 octane mode: Well just filled up with the 100 octane and it was kinda funny the nosel for the pump would not fit the hole it pushed open the flap luckaly. I put in half a tank . Turned on the adjustable rev limit then set the 100 octane mode and it's kind weird to see the shift light to indicate the 100 octane mode . I have never seen the light before.

So I can feel the diifference in the 10 extra hp and the shifting seems to be easier and when I step on it in 1st gear at a 4000rpm roll it just spins the tires. Second gear getting on it from a 40 mph roll is crazy . It screams and starts to spinn the tires. I can't wait till I hit the track.
$30 for a half tank of gas ouch .. won't be doing it all the time but just enough every once in a while.


poly mounts are oin and man the vibrations are bad hopefully they will go away.

 

Hey BCobaltSS, did you ever get that part number for that harness?

 

Nah unfortunalty FNFAST gave me the number to the dealership that he got he nitrous hooked up at and I talked to the one of the service managers that had helped with hooking up the Nitorus "SO YES THE DEALERSHIP WILL HOOK UP NITROUS" you just have to find the right one . He tried to break down the kit for the harness and it did not show it. The guy at the deaership had said that they may have used one that came with the nitrous kit . He said it was a real pain to hook up as far as electrical but once he got it working that it was real "slick" as he put it. Man I wish I lived closer to Wisconsin where FNFAST got it hooked up becasue I would go that dealership and he said that it wauld be warrantable.unless he broke an axle shaft or somehting crazy like that

 

Read this you might need it if your going big power. click the link i have in the thread its great info about the stock parts. https://www.cobaltss.net/forums/show...=1#post1112518

 

pretty good right up on the build for a 2.2 400-600hp damn I espcially like the 11.62 1/4 mile timenot metion of the harness though

 

Man, that sucks! When ever you figure it out can you please let me know how you did it, and if I figure it out before you I'll let you know.

 

From Dynotune's website...

I was under the impression that nitrous had no effect on the injectors therefore it didn't mess with IDC's... Was I wrong in thinking this?

 

dry shots do... you won't have the same problem with wet shots

 

Ah... That's right, we should use a wet shot. I saw dry shot earlier in the thread and was mislead. Thanks

 

The Stage 3 kit is Set up to run with a dry shot, not a wet shot. The biggest clue is is the part in the manula that states the "Stage 3 PCM will increase fuel via the fuel injectors for the nitrous"...enough said as a wet kit does not utilize stock injectors for fuel delivery. My nozzle doesn't even run in front of the MAF...doesn't need to...the PCM controls everything about the shot from when it sprays...to the fuel...to when it cuts off...and when to shut off if a problem occurs.

I have ran 4 bottles through my stage 3 using dyno tunes dry shot and not so much as ONE issue...nothing. Car runs perfect. To me a wet shot on a kit designed for a dry shot is just a waste of money...you can always get a conversion kit if you wish to go wet shot later on. Not to mention you will run VERY rich since the PCM is going to be dumping fuel on top of you nitrous kit dumping fuel

Also says right in the GM manula the injectors with the stage 2 kit are sufficient to run the stage 3 pulley and nitrous up to 7K RPMS without issues...and yes it uses that exact wording.

 

o i was not knocking it i was just saying most people go wet shot on here... your the one putting down the power i believe you
