I just bought my new Cobalt SS last week, and a Friend of mine gave me a 77.9mm pulley for my supercharger. The only problem is, the existing pulley is a push on. The new one of course is a bolt on. I was just curious if anyone knew if there is an adapter to make this setup work on my vehicle.

 

it called a gm stage 2 hub search...

was up jason! good to see you on here man! us army guys gotta stick together!

 

make sure you get the injectors and tune

 

im goin to give him my stg2 injectors if he wants them...

 

What exactly will happen if I put the pulley on without injectors and tune, at least not at the same time?

 

um nothing considering i was running a 2.85 pulley on factory injectors and tune for almost a year since i had the car and who knows how long b4 i bought the car.

 

Cool, any idea what size belt I will need for this new pulley?

 

Stage 2 belt

This is for sure the right size i need?

 

lol yea man u got the stage2 pulley thats the stage 2 belt

 

Ok, just makin sure, cause im about to buy it offline

 

cool man! let me know when u get everything if i can ill give ya a hand if you want and the best part about all this stuff wont void ur warranty

 

Thanks man, Ill definitely let you know when i get everything. Looking forward to see the difference in power.

 

yea man let me know and ill get the # for the guy doin the tune on my car if you want a custom tune... since the gm tune does run a little rich. ill post my dyno #s later!

 

ok cool, I appreciate it man, yeah, lookin forward to seein what it will do. Im thinking about buying those injectors off you when I get a little more money, but first I think I am going to o with a cold air intake, then after theinjectors, ill get exhaust and tune.

 

cool man

 

So, Im kinda upset because I am getting services done on my Cobalt and I have to drive around this piece of crap loaner. An 06 Ford Focus. Definately not the same, But good news. Stage 2 coming soon
