Manhart Racing is keen on BMW models, a statement that can easily be backed up with mentions of the BMW 1-Series M Coupe by Manhart Racing, the BMW M6XR by Manhart Racing, and the BMW M3 E92 Compressor by Manhart Racing, which all received amazing power upgrades from the German tuner. The next lucky Beamer to get worked over is the BMW M3, which received a power boost to the tune of 750 HP!

Manhart Racing achieved the dramatic boost in power by replacing the M3’s standard 4.0 liter V8 engine with the 4.4 liter V8 used in the X6 M. The X6M’s engine already delivers 555 HP, but after adding a biturbo system, it can now pump out 750 HP and 671 lb-ft of torque. This final output is even more impressive considering the standard M3 "only" delivers 420 HP. As a result, the modified M3 will sprint from 0 to 60 mph in just 3.2 seconds and hit a top speed of 217 mph.

In order to handle the extra power, the engine was updated with modified turbochargers, a larger charging air cooler, and reinforced pistons and rods. The car was also equipped with a new titanium-produced exhaust system with two racing catalysers and four 80 millimeter end tubes, and a new brake system.[...]
