BMW E9x M3 Superchargers
G-Power's range of SK2 superchargers from M-Style offer massive gains in power and torque without internal engine modifications. The kits come complete with everything required for installation; ASA compressor, oil supply compressor, drive belt, cast aluminium air intake duct and air box, charge air recooling system, performance air filter, pneumatic boost pressure control and even the ECU re-programming. Everything is reversible should you sell your car and wish to keep the supercharger – the factory OBD and diagnostic functions are retained. M-Style offers three levels of upgrade, the Limited Edition 580 package will, as its title suggests, boost power to 580hp with 413lb ft of torque (£4,995.00). The 610 package provides 610hp and 428lb ft of torque (£6,495.00), the 640 kit gives 640hp and 439lb ft of torque (£7,595.00).
All the kits are relatively simple bolt-on conversions but if you're not confident about installing them yourself M-Style is ready to help by performing the complete installation and ECU upgrade at a cost of £1,000.
