BMW M5 Gets 718 HP from Nowack Motors
One of this tuning companies is Nowack Motors, which has taken the BMW M5/M6’s monster 5.0l V10 engine and turned it into an out-of-this-world mechanical creature.
The engine, which still uses natural aspiration, is now dubbed 5.8 Hans Nowack edition. The unit has had its power rating upgraded from the factory stock level of 507 hp at 7,750 rpm to a mind blowing 718 hp at 9,000 rpm.
The tuner has not released the full list of modifications, only mentioning that it has replaced “all internal parts of the engine”, used advanced coating materials, an ECU remap and two custom air collectors, which are painted to match the M5’s exterior color.
As the engine internals are new, the kit can also be retrofitted, regardless of a car’s mileage. The tuner offers a powerplant warranty of 12 months with no kilometer limitation.
“Forced induction, neither by supercharging nor turbo charging, never was an option to increase the performance of the 5.0ltrs. V10 engine as it does not suit the engine's overall technical layout and characteristics. Furthermore, a forced induction engine based on a NA engine never offers the refinement and reliability of a perfectly engineered and manufactured naturally aspirated high performance engine,” stated the press release.
