i am seriously inquiring a ss/sc cobalt, i have a 06 ls. i have some work done to my ls but i want to know will this pulley that i have on my ls work on the ss/sc? i asked this question in the suspension section but i just want to get some more answers, will my eibach sportlines for my ls work on the ss/sc as well? any information on these questions will be greatly appreciated, thanks in advance.

 

I Think So, I Dont See Why The Wouldnt Just My Opinion

 

I'm pretty sure the springs will work on the ss, but I'm not sure on the undercrank pulley

 

where did you pick up your pulley at? i had a friend do that on his acura.

 

hmmm i woudlnt see why not our engines are almost the same to a certain extent?

 

The springs will fit for sure.As for the pulley it will probably fit but if it is an underdrive pulley it will slow the supercharger down.What size is the pulley?I wouldn't bother.If you want to lighten the rotating mass lighten the flywheel or swap it out. Thats just my opinion.

 

are you talking about the GMPP billet crank pulley?

 

Are you saying you have an underdrive crank pulley that you want to use on your ss/sc? If it does fit and it's a different size then the stock one you'll be changing the speed of your accessories, including your blower which will alter boost.

 

the pulley i have is the RSM light weight crank pulley, it is the same size as the factory pulley, it is just lighter. will it screw up the sc if it is just lighter?

 

I am also curious about this. I just traded in my LS for the SS / SC and I have a **** ton of LS performance parts sitting in my garage never taken out of their packaging... and that is one that I think should be able to go on. But... I was curious as to the benefit of swapping out would be... it's the same size, just quite a bit lighter. So I'm not worried about the fitment, I'm more concerned with it's effect on boost... could this pose a problem? Will I need a custom tune after install?

 

The RSM crank pully will work. Just by being lighter will reduce rotating mass/weight and will do nothing to your boost or tune. You will be fine.

 

where do you buy it at?

 

DOES ANY1 KNOW THE CRANK PULLEY SIZE?im being lazy

 

if it is the same size i would not think it would cause any problems

 

i beleive not 100% sure but i think the ss s/c uses a smaller crank pulley than standard ecotechs.
