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

 

GM offers 3, Intense Racing offers 5

 

how much are people pushing WHP at the stage 5 and what mods did they need to do to accomidate it???

 

2.75 is a mistake. you'll burn that supercharger out before you even knew what kind of power you had. the sc is pretty much at it's limit as it stands. one thing you would want to invest in before even thinking about going any smaller than a 3" are cooling mods. heatexchanger, water/meth injection...etc etc.

 

so even though GM makes the stage 3 knowing that it will mess up your engine they are still gona sell it to us... damn thats messed up lol

 

i have a 2.8, will that burn out my sc?

 

ok just wanted to add something in here real quick does anyone know what the freakin gains will be on adding the stage 3 to stage 5 ??????

 

That kit comes with a dual pass endplate for the intercooler so that helps with cooling since your going with a smaller pulley.

 

wow the lack of knowledge impresses me

 

me to

 

There is so many variables. Cooling and the tune are the bigger ones. Every time you go smaller on the pully size, you are running your supercharger at faster speeds. That just shortens the life of the charger no matter how you look at it.

 

it will not burn out the sc i do not recommend any lower than a 2.85 on 42lb injectors with out a tune and get some cooling mods while your at it u need it

 

all i have is injectors, a tune and a CAI

 

what size injectors, and what kind of tune?

 

60s and i dont know what kind of tune

 

people on this site need to run cars not there mouths, ran my 2.5 for years now and no problems

 

Ya, I bet your supercharger's life expectancy will last as long as a stocks. If your beating the **** out of your car, That supercharger is not liking you. You might just be the exception with a 2.5. What kind of hp are you getting with a 2.5

 

who says i need the blower to stay on there forever when you have options like the tvs. My supercharger is doing just fine i can assure you

 

not saying it isnt. I'm just saying that the life expectancy of the charger drops drastically every time you run a smaller pully. 2.5 is getting pretty darn small, and I bet your really pushing the limits of the charger.

 

yea the lack knowledge on here surprises me.. for one u can go all the way to a stage 6 and expect close to 300hp/290tq... but dude it doesnt sound like u know enough as of now to do that.. to me it just isnt a smart move on your part to get the highest stage kit when u really know nothing about the kits.. it can be very easy to **** everything up on your car without proper tuning and the proper parts and the GM stage 3 states tha it is an off-road kit only.. yes u can still get it but it's not under warranty for a reason..

 

hm, nope treat the car right and your fine

 

ya, unless you know how to do your own tuning, don't just go to the top stage kit. A lot of them are can tunes, and they are not tuned for your exact car. They are good starting points, but they definitely need to be tweaked for other variables. Weather, elevation, and other mods to name a few.

OR LUCKY

 

here is a free tip to all. Don't buy stage kits, make your own and find someone who can tune or learn how to.

luck has nothing to do with it, its in the tune and the driver.

 

Tune and driver have nothing to do with spinning your charger past it's limits.

 

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
