Ok, I know this is a lie, but I was looking through the GM Performance cataloge yesterday and they have the Stage 1 and Stage 2 listed in there as putting out 236 and 241 hp. Now, I know that is crap, and I was wondering what the true numbers are, because if they are that close, why would they even charge like almost $300 more for 5 more hp? That just stupid.

 

you get a lot more power under the curve with stage 2

 

I know there was an article in a magazine, and at the wheels their Cobalt dynoed at I think it was 196whp, and with stage 2 it dynoed at 238whp.
I have no idea about stage 1, in my opinion, just go for the glory and get stage 2 to start with, cause if you are having the dealership install it, you will save money by having them work on it once instead of twice.

 

Stage 1 isn't even worth it. It just ups your redline... that little area between the stock and staged redlines is where the "power" made with the stage 1 kit is found.

 

WHAT WHAT WHAT WHAT! A 2.0SC Cobalt tats NOT dynoing at over 210 HP at the wheels!!??!!?? Why how on Earth did that happen? Everyone here claims at least 210 at the wheels in STOCK form!

So I wonder whos wrong?

 

Oh, I was never going to get stage 1 anyway, that would be pointless. I'm going straight to 2, I just don't understand their reasoning behing "making 5 more hp" for like $300.

I also got a refund check from my old insurance company (Because I switched to Nationwide like 3 weeks ago) for $250. Next paycheck, GM exhaust, here I come. Which one would yall reccomend?

 

i have the sport, i love it

 

Which is the louder one, Sport or Touring? Well, sound doesnt matter too much, I'm going with whichever makes the most power

 

I think they claim 12hp for both. The sport is the louder of the two

 

stage 2 makes something like 20-30 more lbs/tq. . .

Torque if for wining races
HP is for bragging

I just installed the performance cat-back................the only diff. is the muffler assembly. The rest of it is exactely the same parts!!!!!!!!!I think they are the same in terms of gains.

 

Stage 1 isn't totally crap. You can buy the stage one to get the injectors and the tune, then buy a after market pulley system and save a little bit of cash. The stage 1 and stage 2 tune is the same. Just my thought.

 

i would give a great response to this but im currently busy being mesmerized by your sig.

 

I know me too hahaha, just stare at the face and zone out, after a few seconds she scared me!!!

 

ekk i was wrong, just looked it up

Stage 1- 236HP and 205lb-ft torque
Stage 2- 241HP and 218 lb-ft torque

but stage 2 also comes with the modular pulley system and smaller belt. And to be honest, its not that stupid of GM, look at how many people on here have bought stage 2 over stage 1.

 

IMO, getting that hub off is almost worth $300 just to let GM do it...

 

could be bad setup on dyno, or very very hot that day!

 

IDK about the stage kits... but here's something to chew on:

My Mods: Custom Dyno Tune @ Tune Time Performance, ZZP 2.9" S/C pulley, Lucas #42 Injectors, Custom 2.5" Magnaflow Exhaust
The #'s:



Mustang Dyno @ about 40* Farenheight in NJ @ Sea Level
Green is A/F
Red is HP
Light Blue is Torque
*Power to the WHEELS

The Timeslip @ E-Town in NJ:

 

I would tend to agree.It wasn't until I read the directions for my stage II that I realized the part#'s for the tunes was the same.

 

ya thats one way of saying it. i like to say what Carol Shelby said on speedtv.

"Horsepower sells cars
Torque wins races"

I say this to EVERY Honda owner.

example being the honda civic si

197 hp -----sells cars
139 trq -----loses races

 

because when you add the extra boost you get the torque... it increases the power throughout the band, instead of just up top like stage 1..

Go with aftermarket and spend the extra money on a sick dyno tune.. you will not regret it.

that statement is 100% correct. the GM tune is crap. Remember, they have to account for every worst case scenario.. like 110* F in the arizona desert.
The stage 2 tune is Pig rich with fuel.. a slightly leaner A/F ratio is gonna make more power. but too lean blows cobalts up. you have to trust the shop that tunes the car

whan you quote this, please include " quote " -Carrol Shelby

Also, to the same person, you can include my timeslip in that quote. Because I raced a Civic Si Sedan in that race... lightly modded i guess, it trapped 101mph.. but i spanked him.. teach him to nod at me on the line, trying to phase me or whatever.. i think he saw my 17 second pass earlier w/ no traction. must have thought my car was an LS with a fart can!

 

The only reason I don't go with an after market tune is that I don't have anyone any were close to me that does any type of tunning. I think I will get the stage 1 kit with a modular pulley system with a 2.8 or so pulley to tie me over until I can save up the money for HP Tuners and under stand how to use it aswell.

 

well i quoted him just earlier on in my post. but if u want it done like u say here.

lol i like how also my example of the honda civic si was so quickly reaffirmed by a member on here
