G-Power has released details of its 2013-spec supercharger programs for the current BMW M3, offering up to a 25 percent improvement over previous versions.
The company’s new ‘Sporty Drive’ TU supercharger kits feature a redesigned air intake and racing filter, meaning the entry-level SK I option extracts 388 kW (520 hp) from the 4.0-litre V8, up from 309 kW (414 hp). Next is the SK II package, which makes use of the ASA T1-523 ‘charger, superseding the ASA T1-522, allowing an output of 433 kW (580 hp). The final SK II CS (ClubSport) stage includes an additional fuel pump and optimized ECU software and nets you a titanic 455 kW (610 hp).
Other components available for the M3 include a GM3-RS adjustable coilover suspension kit, a 20-inch Silverstone Diamond wheel package with Michelin Pilot Sport tyres and a stainless steel silencer with four 83 mm tailpipes.
