Manhart has created a three-stage power upgrade for the E92 BMW M3. The first stage is a small compressor using a supercharging pressure of 0.35 bar, producing up to 384 kW. With stage-II the supercharging pressure is increased to 0.50 bar that achieves a peak power output of 436 kW.
As if these figures weren’t impressive or scary enough, the stage-III package puts the Manhart Supercharged M3 in the supercar league in terms of power output. A larger compressor from ASA, with a charge pressure of 0.67 bar, is combined with a custom exhaust system that houses two 200 cell race-spec catalytic converters. The stage-III package manages to extract a Koenigsegg CC8S rivalling 488 kW, capable of catapulting the car from 0 to 100km/h in just 3.7 seconds with a top speed of just over 350km/h.
Manhart have used Bilstein PSS10 threaded suspension and 20-inch black BBS wheels to keep the car on the straight and narrow. Continental tyres in sizes 245/30 ZR20 at the front and 295/25 ZR20 at the rear are fitted and should be capable of transferring the hotted up M3′s power to the road – provided some measure of diplomacy is excercised with the throttle. Stopping power is provided by 365 mm brake discs at the front, with floating callipers from the BMW M5 E60, while the rear brake components remain in standard form.
Manhart’s custom exhaust system features a constant diameter of 70 mm and exits with four 82 mm tail pipes. The stainless steel version produces around 13 kW, with the 50% lighter than standard titanium version responsible for releasing 18 kW more power from the 4,0-litre V8.
