no2 25 dry shot
i plan on running a dry 25 shot with meth on the zzp stage 2... if im running meth would i be able to safely run the dry shot ? also should i tune for the meth and have the timing advanced or should i just use it for the cooling effect and fuel mix with no2 ?
mods are 42s, 3 in pulley, k&n intake, cat less dp, magnaflow catback, zzp pcm

A 25 shot? really?
At least run a 50 shot.
On a dry shot you need to fuel it yourself. So if you are running a 3.0 pulley on 42's with a 25 or 50 shot dry I would be using 60lb injectors.
You need to change to 60lbers before you spray it. That will be enough fuel for a 25 shot and a 50 shot.
A Wet shot adds the fuel for you.

I this thread is dead but I want to reiterate this just so you make sure you do it right.
If you have a 3.0 Pulley on 42lber and add a 50 shot YOU MUST HAVE AT LEAST 60LB injectors.
Anything over 90% Injector Duty Cycle you are running static.
To be honest I would take your stage 2 Cobalt Ie 3.0 pulley, Intake, Full exhaust, and hit it with a 100 WET SHOT. Have it all tuned on a dyno.

You should be fine with 42's on the stock pulley and a 25 shot.
If I were you I would buy 60's and run a 50 or 75 wet shot @ least.
LSJ's are known for blowing under heavy heat and not enough fuel to the 4th cylinder. Nitrous won't be as bad on the intake temps and will have enough fuel. If you make 220WHP on your setup without the hose I don't see any reason not to hit it with a 100 shot.
Its safe enough to where Gm has a kit that encourages it.

Wet shot right?
Cause 2.9 and 42lbers on a 50 dry would be maxing the **** out of your injectors.

Your buddy went with a 50 dry shot, He probably also had other mods, So that means he was around 300WHP.
Let me guess he had 42lb injectors some bolt ons and a 50 shot. Well no **** its going to blow up. There isn't enough fuel at all , PERIOD!!
Even if he was running 60lb injectors he might have been close to 90% IDC.
Dry shots are shitty. Run a wet shot, It adds fuel FOR YOU.
Just because your buddy had NO CLUE what he was doing doesn't mean its going to blow up.
Why are there people making over 350WHP on the stock bottom end?? Cause according to your opinion they should have already bent some valves and ****.
Just because your buddy put a dry shot on his cobalt and didn't know what the hell he was doing doesn't mean everyone else will be the same, Sorry but your example sucks.
I know your buddy doesn't know what hes doing for the sheer fact that he put a dry shot on his car instead of a wet shot. That in itself is ignorant.
If a 50 shot was so bad then why does the GM Stage 3 kit come with a 2.9 pulley and a tune to run a 50 shot. Oh yeah thats right cause its reliable if done right.
Who knows more, You or the engineers at General Motors? Im gonna go with GM. To add more proof of how wrong you are.
88958719 Stage 3 2006 - 07 Performance Upgrade Kit
Take your Cobalt SS to the next level with our Stage 3 Off-Road kit!
The Stage 3 kit consists of the following:
• Smaller, 76mm supercharger pulley
• 2-pass intercooler end plate
• Unique PCM which includes a calibration for the smaller pulley, an adjustable rev limiter, a 100 octane mode, and a nitrous algorithm.
Our Stage 3 kit will take your supercharged Ecotec to a whole new level of performance. Stage 3 takes horsepower output to 248 on 93 octane fuel and to 260 horsepower on 100 octane fuel.
In addition to the power increase, you'll also get an adjustable rev limiter and calibration for a 50 shot of nitrous (nitrous kit not included).
For best power, we recommend also installing a high-flow exhaust.
The PCM is equipped with a user adjustable rev limit from 6750 to 8000 rpm. The rev limit is adjusted by pressing on the throttle pedal with the ignition on and engine off. At about 50% throttle the tachometer will show the current rev limit. Pressing the throttle further will adjust the rev limit in 250 rpm increments. This PCM is also equipped with a control scheme for the equivalent of a 50-horse shot of Nitrous. The PCM will automatically provide the proper spark and fuel for A Nitrous up to 500 rpm below the current selected rev limit when the trigger is activated.
Looks like you're wrong.

Well said.....nitrous done right can be very safe. Im running a 100 wet shot on my SS/SC while runing a 2.9 pulley as well as I/H/E/CAI and a heat exhanchanger and ive gone through 3 bottles so far with no problems and a perfect 11.2 AFR.
