The Evolution Motorsports GT500 was 100% ground up designed, engineered and manufactured in house. The concept for this power upgrade was to build a safe and reliable power upgrade that would maximize the potential of the flat 6-996TT engine. Some of the known hurdles were to strengthen the internal engine components, deliver enough fuel, air and software calibration to balance the system. The end result offers an extreme power level while maintaining excellent longevity and reliability under some of the harshest conditions.
