I assume you'll be porting the blower so that it can spin safely to what, 20k rpms ? The stock safe limit is 16k rpms...

Im not sure you'll get anymore boost out of it past 2.5" but then again your probably not revving the car as far as the cobalts are.
Check out my car....

From my understanding stock safe limit is set by a thermal expansion coeffiecient of the rotors. You spin them to fast, they get hot, then they touch, really bad things happen after that....

I'm pretty sure I was told by peeps over at cobaltss.net that porting the s/c allowed to rev faster safely... they might be wrong though...

Something I thought of tonight:
Under wot, ~9 psi non intercooled in 1st gear, I noticed my afr's were 10:1. Probably richer because that's as rich as the gauge reads....
Anywhoo, with a smaller pulley, will it still run just as rich at 9 psi?
Is the amount of fuel injected based off of rpm vs tmap, or tps vs tmap?
ouch that's rich ! what I like though is that probably this means you can install a 3.0" pulley and still be on the safe side A/F wise...
