640 HP BMW M6 Is The Boogyman of Tuning [Photo Gallery]
When he new M6 left the factory, it did so with the most powerful stock engine they make a 4.4-liter producing no less than 560 HP, but the tuner increased this to a more impressive 640 HP and 777 Nm of torque with the use of G-Power Bi-Tronik III custom ECU mapping and a new ASA Series supercharger.
Let's name just a few cars that are now less powerful than it: Ferrari 458, McLaren MP4-12C, Mercedes SLS AMG and the list can go on forever.
To cope with the improved engine, the G-Power was fitted with 21" G-Power Silverstone RS alloy wheels with Michelin Pilot Super Sport tires, G-Power coilover suspension and a complete G-Power Ceramic Braking Kit.
Stemming from all these custom bits and peaces, the G-monster finds it fit to accelerate from 0 to 100 km/h in 3.8 seconds and reach a top speed of 315 km/h.
