The latest creation from NOWACK MOTORS is called the N700 and it involves the BMW X5M and X6M for which they applied serious modifications in the engine compartment as well as a number of visual enhancements.
Cutting a story short, the NOWACK N700 BMW X5M and X6M can now pack 715 horsepower and 845 Nm of torque at 2.600 rpm thanks to a series of mechanical upgrades that include, forced engine induction from two turbochargers, larger pistons, a new crankshaft and camshaft, high performance connection rods, new valve pockets, special intake valves and other modifications.
With this almost completely redeveloped 4.4-litre V8 engine that used to produce 555 HP, the NOWACK N700 BMW X5M and X6M can reach new performance levels, and even though actual figures have not been released the tuner mentioned that the usual speed limiter has been reset to 330 Km/h.
NOWACK MOTORS press release :
World famed high performance engine developer and manufacturer NOWACK MOTORS, proudly announces the birth of its latest masterpiece, the NOWACK N700, to all owners of the latest creations of the BMW M GmbH, the X5M and X6M.
Based on the M GmbH's 4.4ltr. Biturbo V8 engine offering a maximum power of 555hp, NOWACK MOTORS created a new technical masterpiece.
Deliver a standard X5M or X6M to the small but highly experienced specialized German engineering and manufacturing outfit and they'll nearly strip it back to a skeleton. All that's left of the engine is the external look, which remains the same than in the standard cars.
It all starts with the disassembly of the standard engine, leaving only the external parts of the engine unchanged.
First, the cylinder block undergoes the process of machining (boring/honing) to fit the new NOWACK MOTORS oversize high performance pistons. Afterwards, a unique Alusil coating is being applied to the cylinders for less friction. An all new, fine balanced NOWACK MOTORS exclusive crankshaft, individually weighed and fine balanced high performance connecting rods, 8 fine prepared, especiallycoated, exclusive high performance pistons with new valve pockets, specially coated piston rings and piston pins, high performance camshaft (in-/outlet), special intake valves with bigger diameter, extensively modified free flow high performance cylinderheads with re-engineered in- and outlets, each optimized on NOWACK MOTOR's in-house SuperFlow 1020 flow bench, high performance camshaft (in-/outlet) and various modified components of the valve drive inclusive of special valve springs
complete the exclusive mechanical internals of the N700.
NOWACK MOTORS extensively modified both turbochargers in order to provide a better and smoother performance perfectly suiting the requirements defined by the complete re-engineering of the internals.
The optimization of the intake air flow inclusive of high performance free flow air filters, modified high performance exhaust manifolds leading to an all new, complete NOWACK MOTORS high performance sport exhaust system inclusive of high performance motorsport catalytic converters and rear silencers, complete the list of external hardware components.
Upon completion of the mechanical manufacturing process, each car's ECU is being individually re programmed. Needless to say that the works speed limiter is removed and set to 330km/h.
The maximum power of 715hp and torque of 845Nm at 2.600rpm. offered by this most sophisticated, bespoke powerplant can be seen as an impressive side effect resulting out of the extensive engineering and manufacturing knowledge.
