Wesitec Engineering tuned a Mercedes C63 AMG Black Series, from a standard 507hp to 670hp, but when running on race fuel it achieves in the region of 780-790hp.
As you can hear the Merc's V8 sounds pretty mega as the car completes some burnouts and races up the drag strip at Shift S3ctor Airstrip Attack 7.
