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, especially
coated, 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
