I was wondering the same thing actually. One of my friends has a guy who actually fabricates pullies for his Saleen Series II blower on his mustang (eaton M90), so I was going to get some measurements on the SS's blower pulley and see if he can create a smaller one. Does anyone know at this point what kind of power the SS 2.0 Ecotec internals can handle?

stock is 3.5", you can't go less than 3" because the tensioner can not get all the slack from the belt. Not to mention no one has really tested the 3" pulley yet, wanna be the guinea pig?

We are currently running a 3.150 pulley from billet flow on my buddies ION. 14psi!

No problems what so ever, and you can go to a 2.9 without getting a bigger idler pulley. But we highly recommend it. look at my post about the billetflow pulleys.
I put a 2.8" pulley on my car last night and the belt had a load of slack, I really don't think the 2.9" is going to make up for the enormous ammount of slack that I had.

I'm tired of sitting around and waiting for stuff, so I gotta get something to hold me over....:D
Look' what I found:

Our SS's are M62's right? So why wouldn't this work? Well I don't know the size of our stock pulley and if the belt is the same width. What do you guys think?
VaMP, just because you have a M-62 Supercharger installed on your vehicle, does not mean that any pulley, regardless if it is Interchangeable 2 piece, or a Press On fit pulley, will work on your vehicle, as it will NOT!

The differences on all M-45, M-62, M-90, M112 superchargers (Depending on Vehicle Application) have difference Hub Area Variations on the Offset, to properly seat the pulley onto the supercharger housing snout shaft. Do not be taken in by someone telling you that all pulleys will work, because they will not.

Also, on these Ion Redlines & Cobalt SS's , it would seem more practical to install an Interchangeable/Modular style Pulley Unit, as you would want to change to different sized Pulley Rings, dependant upon the amount of boost you would want to use. Also, with using smaller pulley sizes, one thing to remember is the Tuning and Setup of the engine, to handle the added boost at wide open throttle. Hope this helps.

for those who have tried the 2.8 and 2.9 pulley. aren't you afraid of getting knock with that small of a pulley?
yes I am. It was just a test and then it came off.

i have a 3.00" DUB pulley system that is made for the cobalt ss/redline and i am installing it today. however, you cant overlook the PCM. the pcm limits the ammount of boost under certain circumstances, one being if the boost is above 12 psi. so you can put a pulley on. but you will actually hurt the performance of your car if you do. i am testing my cobalt on the dyno today and my tuner is going to help me get through the PCM, but it might take a week or more because i want to get it done right, so the car is not affected in a negitive way. when i do get the PCM prob. solved, i am going to offer a boost package for the cobalt/redline. email me if your interested. Thanks, John
