I made a thread about the same subject when I was going to get a 09 but now that I am getting a 07 SuperCharged cobalt I am not sure what to do first.

The car does not come with opt-b and my understanding is to run dual pass you need option B. is opt b just a extra tank and hoses?

After I get option B the next thing I want to do is dual pass and also add on a intercooler.

I think once I have these two things accomplished I am going to get header/downpipe and then CAI and put all 3 of them on at the same time to fell the difference.

Besides Stg2 and a meth kit what can I do to this car?




I know the intercooler won't do to much while I am stock but when I take long trips to the shore and stuff I dont want the car to be heat soaked.

Is there a way to get the PCM to leave the fans on after the key is out for about like a minute or so?

 

Option b is one plumbing choice you have when you do the dual pass endplate, you could also use option a but that is a little harder to bleed the system.

You are looking for a additional heat exchanger you should look into the kit we sell.

The possibilites are really up to you, what ever pulley you want, what ever exhuast, different injectors, return style fuel systems. Lots of choices, if you need any help pm me and i can point you in the right direction.
