The high-revving V8 power unit of the BMW M3 GTS has proven itself as the ideal starting point for the forced induction technology practiced by G-POWER with ASA superchargers. Because the engine with a 10% greater displacement of 4.4l has got even larger reserves that can be used for an additional output increase than the 4.0l standards M3 power unite, that has successfully managed full throttle test bench drives for more than 350 hour non-stop and therefore is rightly well-known for its durability.
