Well, if a stock TSi is rated for 195 HP at the crank, and the Cobalt is rated for 210?? at the crank, with a 16G and some good driving, you'll eat him. Superchargers only put out like max 8-9 psi and the engine isn't much bigger than the 4G63, so I don't think you'll have a problem. Go for it and good luck!!
