Well i can definitely say this, the Cobalt SS/TC SURPRISED ME! My buddy mike had just gotten one right about the time i finished the BPT swap on my Escort GT.
My EGT did 200whp, 225wtq, weighed 2300lbs, and we got in ~ 8-10 40mph 2nd gear pulls... All with the same result.
Dead even all the way to about 145mph. My EGT would pull a fender ahead, SSTC closed the gap.
Shift, EGT up, Cobalt close the gap, every run! I'm not a GM fan at all, but I give them props for this one! 5 different Cobalt SS/SCs would be 4 cars+ behind me, so its a hell of an improvement w/ the turbo!
Now when i ran an MS3, which had TBE and a BOV on 19psi i stayed on his back bumper but started creepin by top of 4th bottom of 5th.
Sorry but that story doesn't make a whole lot of sense.
A MS3 running 19psi would hand you your ass (You wouldn't be creeping by the top of 4th) if a Stock Cobalt’s/TC was about even with you until 145mph. A stock MS3 holds ~14.5psi, upping the boost to 19psi alone will yield about 25-35whp over stock which is plenty enough to walk a Stock Cobalt SS/TC. It just doesn't add up...
Other than the fact I think it looks like a “steaming pile” inside and out I don’t think it’s a horrible car. However, some of you are making sound like it’s the second coming of Christ.
P.S. The MS3 has a by pass valve "BPV" by the way, not a blow off valve "BOV".
