The BMW M3 is a superb automobile; it goes from 0-60 MPH (0-100 km/h) in 4.4 seconds and will cover the quarter mile in 12.7 seconds. From the factory the M3 is powered by a 414 HP 4.0 liter V8; however that did not stop the German tuners G-Power from making ridiculous amounts of power from the vehicle. With the addition of a supercharger they were able to make 635 HP.

The rationale behind the supercharger was to significantly increase the low end torque of the M3 as well as increase power throughout the entire RPM range. For those who are hesitant to boost a factory BMW engine, but still want more from a M3, G-Power has developed an engine swap package where they will transplant the 550 HP V10 from the M5 into the smaller and lighter M3. Now that’s a German muscle car.

More info and performance packages after the jump

G-Power also offers a host of more civilized performance packages such as their EVO I package that will get you an additional 103 HP over the base V8. This is achieved with the use of and intercooled supercharger, larger fuel injectors and a stainless steel exhaust system. Also available is the EVO II system, which gains an additional 24 HP over the EVO I package resulting in 541 HP.

There is also an EVO III set-up that utilizes an upgraded supercharger, a cold air intake with racing filter and a high capacity water to air intercooler on top of the engine. Inside the block 10.3:1 compression is achieved with lightweight low compression pistons. The EVO III package also comes with stranger connecting rods to ensure that nothing comes out through the oil pan due to the added stress.

For those of you who require more modest modification G-Power offers the G1 tune using a computer upgrade resulting in a power gain of 21 HP, the unit will also raise the top speed from 155 MPH (250 km/h) to 187 MPH (302 km/hr). The G1 Plus SII package that adds 43 HP by using high flowing catalytic converters a freer flowing exhaust and sport air filters.

No official performance data is available at this time, but considering that the company has also produced a record holding 228 MPH M5, any of the upgrades should bring significant improvements.
