Yes you are harming your system, and frying your battery with a voltage output that high. First, double check that your battery is good, and you're not trying to charge a dead cell. Then, take your alternator back to your rewinder and have it redone. Or go to Summit and get a Powermaster replacement.

The amperage output is supposed to go up, but the charging voltage should stay in the 13.5 - 14.5 range.

Cobras don't have a lot of electrical needs. CD ignition, electric fan, e-code halogen headlights, even a sterio amp in the trunk. You don't need a 140 amp alternator to run this. I have a standard 63 amp Delco alt, and all the electrics work fine.
