Has anybody bumped up their boost from 12psi stock? Does anybody make a pulley? Theres no way to use a boost controller like a turbo set up is there.

No, you can't use a boost controller. There is a thread on here about a redline who did a pulley swap though, you should find it if you do a search.

Edit: I decided not to be lazy and found it for you:

enjoy.

 

I just punched it and finally got to 12.5 lbs. I handt before but after a long peelout it was broken into 12 lbs already. I really love it now even more!

 

MAYBE IT WAS SET WRONG FROM THE FACTORY,BUT I'M BOOSTING 13LBS.YOU CAN GET PULLIES ON (YOURCOALT.COM)

 

is that the only way to raise boost on a supercharger? by buying pulleys?(sorry for the newb question, just curious)

 

Yes, unfortunately it's the only way.

 

how much boost can the stock blower on the cobalt handle?

 

Some one on the site is running 17 psi. I am not sure on it's max potential. I would guess 19-20psi, I could be wrong though.

 

have you dynoed your car yet or ran it at the track if so what numbers are you guys seing im intrested in one of these cars

 

psifi kits run 17 psi i believe, however they have a piggyback unit that is wired into the ecu and allows the boost to be so high. they have a 2.8 inch pully. i have a 3.0, however i have not installed it yet, either this week or next when i have some time at home....... hoping to see around 14-15, with the bypass mod, however i dont know if the boost guage will actually show it......

 

You can get 20psi with the right pully and piggy back but I would wait for GM unless you want to cover your own problems,Cuz if you pop the motor $$$$$
