There's proof out there that you can take an already powerful vehicle and give it more power. Case in point is the slightly hotrodded 2008 Koenigsegg CCX. The owner of this delectable car decided that 806-horsepower in a 2,600 pound package just wasn't enough. The twin supercharger equipped 4.7-liter V8 gives the CCX an estimated top speed of 245 mph.
This specific one received an upgrade from a Koenigsegg factory representative to bump the stock 806-hp to 980-horsepower. The crazy part is that this car was then listed on Ebay! There's no indication from the listing what the performance numbers are from the extra 174-hp, but it's sure to be insane.
