German tuner Wheelsandmore has a new upgrade package for the Mercedes SLS Roadster that boost the output of its V8 engine to more than 700 horsepower. They’ve achieved this using the art of supercharging.

It is actually a two-stage program, with stage 1 including ECU remap, sport exhaust and catalysts, and revised a intake, good for 635 hp and 700 Nm. Stage 2 will add the supercharger and crank the power up to 704 hp and 855 Nm.

The full-fat version is capable of going from 0 to 100 km/h in 3.6 seconds and reach a top speed of 330 km/h.

Complementing the power is a nice set of 6Sporz2 21-inch wheels with 305 section rear tires, and adjustable coilover suspension complete with a lift system.
