BMW M3 boosted to 646bhp by Manhart Racing

The upgrade kit comes in three stages, with the first stage consisting of a small compressor to provide boost pressure of .35 bar. This boosts power up to 508bhp from the standard 414bhp. Stage two meanwhile increases the boost pressure to .50 bar, which then increases the power to 577bhp.

The final stage adds a larger ASA compressor to provide a boost pressure of .67 bar. At this stage, larger exhaust and two race-ready catalytic converters are also installed, to provide a final power output of 646bhp.

This enables the modified M3 to go from 0-100km/h in 3.7 seconds, and reach a top speed of 350km/h. Manhart Racing has also given the M3 a new body kit, consisting of 20-inch BBS wheels, Continental tyres, and large brake discs, as well as leather, Alcantara, and carbon fibre mirrors
