A few from a local event. Lethal Injection won the Superboat class. It's running a 640ci putting out 1100-1200 hp. Best sounding boat though was #47 Rylock, running a 357ci supercharged engine, putting out 1000+ hp. The whine of the supercharger was simply awesome. These things go from 0-100km in about 3 seconds, great to watch, and the cornering is astounding.
