how many stages?
just a quick question... how many stage kits are there out there? I know that GM has the stage 2 kit with the shorter pulley and the bigger fuel injectors, but I'm hearing alot of talk about stage 3, stage 4, and stage 5 kits... can someone fill me in on how many acttual stage kits there are lol and also the gains that you get with them besides the stage 2 kit. oh and one more thing where can I find the 2.75 pulley instead of the pulley that comes with the stage 2 kit I'd like more boost please 
Nate
if you want numbers on gains go to Coablt-addiction.com and check out their stage kits. they post numbers
sorry, thats Cobalt-addiction.com
my advice, get stage two from gm, and get a private shop to retune it (minor tweaks) other than that, enjoy the power this car puts out already

Gm stage 2 is all you need, everything can go from there, you can drop the pulley down to a 2.7 with the GM stage 2 hub with the Smoothflow pulleys which is as low as you should ever go on the stock blower anyway, the only thing in stage 3 worth buying is the dual pass endplate, for more power you can retune and swap to 60lb injectors, any exhaust ZZP 3 inch is nice (GMPP stuff is too small and conservative to my liking)
some of these companies are murder for your engine with these stage 5 kits, 2.5 pulley is way too damn small, crappy canned tunes that may not even work if you dont have a stock intake, how crazy is that?

THANK YOU!!! Finally some one posts what I needed to hear. to the rest of you guys, just think about this you are arguing on the internet, calm down you all need to keep with the topic people post not something else that you want to post, if you guys wanted to argue then you should have emailed each other or something, instead of wasting my time reading your dumb ass comments. 
that is what is fun about a public forum. We like to discuss, and we all don't have the same opinions. I just read your stupid ass comment, so stop wasting my time.
thanks alot rodimus. I appriciate your time and telling me this info I didn't plan on going above a stage 2. because I figured Id have to do a lot more mods to make sure the engine dosn't blow up on me lol. would you suggest a heat exchanger????
The supercharger is still spinning without the boost being created right? So your Spinning the damn thing way past the eatons limits. Has nothing to do with the tune.
you know what the max sustained rpm is of our gen 5 don't you? You know the max instant it can hit to don't. You must also know that eaton test all there blowers for 500 hours to ensure the qaulity of the blower. yeah you know that right...
they must test them with the 2.5. UMMMM, Right!
Everyone that intends on keeping an Eaton Supercharger on the car regardless of what size pulley should upgrade the heat exchanger, even being stock during the summer I would benefit GREATLY from a better one, crusing temps of 110-120 when its 90 out, idle it will shoot up to 160, certainly not where you want to be
its a disagreement, that's what keep these forums going
this argument is kinda childish, but anyway ther is no sense in getting pissed off at someone that 1. you dont know. 2. you dont have to live with or talk to everyday. if you want to put a smaller pulley do it. if you dont want to go any lower a 2.7 then dont. just dont have a f*cking coronary about some else car that you dont even make the damn payment on. thats just my opinion dont hate me
