G-Power Supercharger Boosts M3 to 500 HP

For the current BMW M3, G-Power offers a new supercharger system that sets new standards in regards of design, quality and performance. Using gentle light-pressure charging with just 0.3 bar (relative) boost, the output of the V8 engine is pushed from 420 hp to 500 hp and the torque increases from 295 lb-ft up to 354 lb-ft. After 9 months of intensive development, starting with the CAD design, followed by prototyping and completed with test drives and hot climate tests in the United Arab Emirates, the result is awesome.

The modifications to create the G-Power Tornado let the BMW M3 appear completely changed. However, from 3000 rpm on the supercharged M3 pulls like a standard BMW M3 spinning twice the revs. From 5000 rpm on until redline the G-Power M3 Tornado really cooks, providing 20 percent more torque than the factory car, delivering what the company calls, "acceleration that feels like being dragged by a bungee cord."

The heart of the G-Power Tornado is the supercharger system, the all new T1-518 ASA centrifugal supercharger, the same superchargers that Alpina uses in its B5S, B6S and B7 models. The use of OE-quality components is part of the G-Power philosophy and one of the secrets for the extraordinary quality, reliability and performance of the G-Power products. For use in the G-Power Tornado the ASA T1-518 has been been specially tailored to provide the a huge volume of air to feed the high-revving 4.0-liter V8.


But the ASA supercharger, flanged to the engine using a CNC-milled high-strength mount, is not the only high-tech component of the G-Power M3 supercharger system. The engineers spared no cost during the development of this supercharger system. Among others they even did a sophisticated, computer-aided simulation which analyzes the conditions of the air-ducting engine parts. The goal of this extensive research is to improve the efficiency of the G-Power supercharger system to the best possible performance. The surprising results? The G-Power supercharger system is actually capable of reducing fuel consumption of the engine.

A further key feature is the complete cast-aluminum, large-volume air box, including eight lightweight integral resonance induction pipes, that is responsible for the perfect throttle response and optimal torque curve. The G-POWER M3 supercharger system is completed by the large air-to-air intercooler that is located in the vehicles front, which cools the boost temperature down to an output optimal level under all circumstances.

Of course the performance figures benefit from this huge output improvement. The figure from stand still to 124 mph improves from 15.8 seconds (stock, 6-speed manual) to 13.5 seconds.

The top-speed limiter can be deactivated, based on the selection of proper tires. In combination with the 20 inch G-Power Silverstone Diamond wheels and the Michelin Pilot Sport tires in 255/30ZR20 and 295/25ZR20, a top speed of more than 200 mph can be achieved. Especially designed for the BMW models, the G-Power Silverstone alloy wheel forms a contrast to the great mass of other aftermarket wheels, due to the successful combination of double spokes and the "concave design" typical of G-Power. The diamond cut provides for the fascinating, dynamic appearance of the G-Power Silverstone rim, in contrast to the silver-graphite coated wheel body and the bolt applications of stainless steel. An additional feature of the G-Power Silverstone rim is its weight-optimized design that allows a low rim weight with the same stability, compared to other standard wheels.


A perceptibly improved impression of convenience and a considerably increased agility accompany the minimization of the unsprung mass: advantages of the G-Power Silverstone rim, which you can factually experience above all in connection with low-profile tires. Further improvement of the road handling is realized through the continuously height-adjustable G-Power coil-over suspension G3M-RS with nine selectable settings each for bound and rebound.

Next to the output and the suspension of the BMW M3, G-Power has taken care of the sound, as well. The G-Power 4-trim sport rear muffler with its 4 x 83 mm tailpipes gives the BMW V8 a deep, throaty sound that turns heads but is at no time annoying. The G-POWER M3 rear muffler is available made from stainless steel or completely out of Titanium which is 31.9 pounds lighter than the factory part.

The interior is upgraded by G-Power with precious carbon panels, a speedometer with G-Power logo scaled to 200 mph, a sporty aluminum pedal set and on demand a tailor-made leather interior. The exclusivity of each G-Power M3 Tornado is documented with a special badge in the interior and on the supercharger system that features the G-POWER serial number.
