For those with GM Stage 3

For one I would only run a dry shot, that is what it was designed around. PCM adds fuel to compansate for the nitrous. Yes, you can spray in 100 octane mode. FYI, not not run a smaller pulley that a Stage3 pulley, especially if spraying. Tried my 2.8 pulley on the Stage3 PCM, way slower, pulled timing!

Well, I tried it and it didn't work. When you ativate the 100octane mode, it will dis-engage if it detects knock. if it doesn't detect knock, the upshift light will stay on and you are succesfully running on a 100 octane tune.
Actually, the guys from GM Eternal were at LACR with me when I had the set-up. It doesn't work. Stage 3 if definetly worth getting, but with nitrous! I have it and damn, I love it!!! It actually hits about 19~20lbs of boost with the stock stage 3 pulley once you spray. If you get smaller pulleys, then you will definetly boost past 20lbs, lean out, screw-up your injectors and end up posting up a thread, "My Cobalt sounds like a Subaru"

I guess I'll just buy everything seperatly... i think the stage 2 injectors are 42.5 so i'm gonna get them from crateengine w/ injector harness, along with the stage 2 hub and bolts, belt, and the stage3 pulley oh can't forget the stage 3 ecu.. thats the most important... Its actually cheaper to get everything separate then it is all together.. hmmm

I'm personally going Stg 3 with spray. To me adding a smaller pully is going to wear your engine all the time. N20 is going to run you when you really need it to go that fast, but for day to day, stage 2 gets you up an onramp like a bat out of hell anyway.
Having the stage 3 pcm protecting your engine during the shot is good too.

The only problem with Stage 3 and N20 is it is kinda the stopping point. Most stuff is cost prohibitive at that point so it should prolly be on to the buy a faster car mod anyway though.

True... If the cobalt works out for me and everything i may even upgrade internals in order to rev to 8,000... that'd be sweet.
a cobalt capable of runing in the 12's is good enough for me.

Yeah, it is good enough to get the W....T....F..... out of most people when they are a bus behind.

While doing some research, I was wondering what would be the safest pulley to run on the stage 3. I know the stage 3 runs more lean then the stage 2 but i wanna know if i can run a 2.95 instead of the 2.99
I added another question...
I was wondering if you could only spray nitrous on 93 or 100 octane mode? the reason i ask is because of the fact that i want to run 93 on meth in order to run on 100 octane mode... but i want to use nitrous so...
I wanna kno if its safe to spray nitrous while on 100 octane mode runing 93 pump gas with meth... THanks

Very pleased with it. Runs very smooth with enough power for my needs. Pulls as good if not better than my STG2 w/2.8. Others that have riden in my car are looking into the same setup.

Wow... there seems to be alot more people with the stage 3 that i thought... or at least looking into getting it
another question...
since the 42.5 pound injectors are basically maxed out while on spray... is it possible to switch to 60lb injectors without any problems. do you have to tune for them??

IMO, stick with the full Stage 3 setup as per instructions without modifications. Some will disagree, but I am yet to see a problem with Stage2 or 3.

I stated in a previous post, my drivebility suffered with the Autolites, regardless of the gap I set them to. Top end misfire was the most prevelant, (poof around 6700rpm) and some excelleration stumble. Switched back to stock plugs @ .35 and been fine ever since. I have watched knock retard on a Tech2, and saw none, also monitored IDC and IAT2 readings. IDC's were high, but not maxed. IAT2 peaked @120 degrees. I have total confidence in the Stage3 setup and pay no attention to monitoring it. A friend and customer of mine that previously owned a Cobalt, installed 60# injectors w/2.79 pulley and ended up with more problems than with the 42's. "This was also with being dyno tuned by a realiable tuner."

We are refering to GM's Stage3, the parts in ( ) in my sig. As far as how fast?, not sure what is ment. Accel time?, 0-60, 1/4 mile? I don't race in straight lines, never timed myself that way with my current setup.

UPDATED!!
I'm new to the whole nitrous thing but since I've got my 2.99 pulley, my 42.5 injectors, and my stage 2 belt all i need is the stage 3 ecu and im ready for the install. However, I guess i should wait until i get a full exhaust to install it but o well... My question is since im new to nitrous [B]Well basically how does the stage 3 work the nitrous. Is it basically a one switch deal where it'll spray it as long as its"
rpms>3500
rpms<500 from rev limit
No engine codes
Throttle pos.>90%
So does this means when the switch is own it'll spray it when ever all those parimeters are met or does it use a button for the injection??
Thanks for any input.
bump
I'm not giving up... someone please help
