We have details and photos of the BMW M3 Coupe from Manhart Racing. The story inside.

German tuners Manhart Racing have released photos and details of their version of the BMW M3 coupe.  The engineering firm boosted the E92's engine output to 655 PS (482 kW / 646 hp), while reducing 0-100 km/h time to 3.7 seconds.

Top speed goes above 350 km/h (217 mph).

The upgrade was made in three parts, with the first stage adding a small compressor to provide boost pressure of .35 bar.  This bumps up power to 515 PS (379 kW / 508 hp) from the stock 420 PS (309 kW / 414 hp).  Stage two bumps up pressure up to .50 bar, which brings up horsepower to 585 PS (430 kW / 577 hp).  A larger ASA compressor is added in the last stage, providing pressure of .67 bar.  At this point, larger exhaust and two race-ready catalytic converters are installed.

In one of the pictures, some might notice the G-Power branded engine cover.  We suspect the Manhart kit is a development on the G-Power kit, as they also use an ASA supercharger.  The G-Power package boosts power to 600 PS (441 kW / 592 hp).

20-inch BBS wheels, Continental tires, and large brake discs are also included.  Leather, Alcantara, and carbon fiber mirrors round out the package.
