The BMW M3 CRT and the M3 GTS share a unique bond. They’re both powered by BMW’s S65 4.4-liter V-8 engine. Unfortunately, that engine has been discontinued, leaving a gaping hole among those who like their BMW engines to be high-revving monsters. Fortunately, G-Power is here to save the day, or at least introduce one last engine upgrade for the legendary S65, using both the M3 CRT and the M3 GTS.

G-Power->ke1323 claims to be the only BMW->ke178 tuner to have an engine upgrade for this engine. If true, that’s a huge deal for the limited number of owners who actually have the M3 GTS and the M3 CRT. Remember, these models are two of the most exclusive M3->ke2366s the company has ever released. The M3 GTS was released in 2010 and was limited to just 150 units. In 2011, BMW followed it up with the release of the M3 CRT, which was even rarer with just 67 units built.

Both the M3 CRT and the M3 GTS came with an output of 450 horsepower and 324 pound-feet of torque. But with G-Power’s SK II “Sporty Drive“ TU supercharger system, the output for both models improves to 650 horsepower and 480 pound-feet of torque. That’s a dramatic rise in power that also results in the sports cars' 0-to-60-mph times dropping from 4.4 seconds to 4.1 seconds. Likewise, the top speed also improves significantly from 180 mph to an impressive 200 mph.

G-Power’s “Sporty Drive“ TU supercharger system is available at a price of €23,500, excluding tax plus installation. That’s about $32,000 based on exchange rates on 7/8/2014.

BMW M3 CRT & GTS By G-Power in Detail

G-Power undertook careful research and development to achieve the incredible performance increase of this particular supercharger system. Strenuous work was done on reinforcing a handful of the engine’s components, including the engine block, the crankshaft, and the connecting rods. From there, G-Power used CAD engineering and prototyping to determine the quality of the supercharger system. Once that was accomplished, the engines were sent out for test drives in various locations, from the German Autobahn to various hot-climate countries in the Middle East.

G-Power knows the value of having an excellent tech partner like AVL on its side. AVL’s technological capacity to measure the exact peak pressure that develops in the combustion chamber allowed G-Power engineers to create a custom software for the engine’s ECU.

G-Power also tosses in a lightweight titanium exhaust system with 100 cpsi metal catalytic converters. This exhaust system is a bonafide G-Power creation, capable of producing the needed reduction in exhaust back pressure. The result of that is a sports car that growls with the best of `em.
