You can do a great many things to improve horsepower like burning higher octane fuel, turbocharging or supercharging the engine, improving the exhaust flow, or any one of dozen other common horsepower-enhancing modifications.
The simplest way would probably be to just buy a 2011 Mustang V6 with more than 300hp of its own.
Best of luck. I hope this helps.
