I am going to go against the grain here, and go with the Supercharged car! As stated above the current Cobra is built pretty strong, so we know that we will have room to work some more horsepower out of it, I mean really with a CAI, P&P work, chip, smaller pulley, and exhaust you can get near 475-490hp with these cars, and probably 500-525 with the 415hp motor. The 200 pound weight difference can be eliminated by emptying the trunk, and taking out the rear, and passenger seat, before you know it your N/A car with the same mods is sucking exhaust from the S/C car...
