G-Power, Tuning
So it came BMW Z4 Roadster’s turn to receive modifications from guys from G-Power, changes in all directions, engine, suspension, wheels, and tires. The G-POWER program for the BMW Z4 E89 touches all key components and lets the nifty BMW Z4 appear even more sporty, beautiful and last but not least exclusive.
Twin-turbo on Z4 sDrive 35i, benefits from a module BI-TRONIK that makes from standard engine of 306 hp and 400 Nm, a propeller that will develop 345 hp and 480 Nm, with which the roadster will reach 100 km / h in 4.7 seconds, with a half a second faster compared the engine factory.
Tuners also brought a new suspension and drum with a better “sound”, beside the four exhaust pipes. Wheels that fitted the new Z4 measures 20 inches and come with Michelin Pilot Sport tires 255/30 ZR 20 in front and 295/25 ZR 20 on the back. Further improvement of the road handling is realized through the continuously height-adjustable G-POWER coil-over suspension GZ4-RS with nine selectable settings each for bound and rebound.
And I think is the case to talk about prices: wheels + tires cost 4474 €, suspension € 1256, evacuation € 1978 and engine upgrade € 1978, plus €403 for installation.
Come on, that if you have money for Z4 Roadster, certainly you will find something more through pockets for these upgrades.

G-Power, Tuning
When the old M3 was launched the Germans has allowed keeping the tradition. I mean they never even thought about supra alimentation for gas propeller. The truth is there was no need, plus the BMW cars were adored by fans and for this reason – engine on sucked gas, of high speed.
But BMW’s were surcharge with turbo or mechanic compressor and then tuners being responsible for this. Now there are already turbo engine (gasoline) official, but that does not mean that tuners not resort to this solution.
G-Power has chosen to increase the performance of former BMW M3 engine, an 6 cylinder in-line, 3.2 liter and 343 CP. Tuner has mounted a perform compressor and the result is that the old M3 becomes more efficient than today.
Sure, the comparison is obviously forced, but you can imagine what satisfaction can be exceeded in the accelerator model has replaced the car that you drive. Maximum engine power has increased from 343 HP to 450 HP (30 HP more than delivers V8 – The 4 liters of the current M3), and reached maximum torque to 450 Nm (365 Nm from as is version number).
As a result, acceleration from 0 to 200 km / h is possible in 14.7 seconds, compared to 18.1 seconds for the version of the series aspirated, of the engine; the difference from the current M3 is a second less for the same performance. Maximum speed up to pass 300 km / h.

German tuner G-Power has developed a supercharger system for BMW M3 model, called Tornado, which sets new standards in regards of design, quality and performance. Using gentle soft 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 400 Nm up to 480 Nm.
Entire 9 months of waiting, were not left without amazing results. Intensive development started with the CAD design and followed by prototyping and completed with test drives and hot climate tests in the United Arab Emirates.
500 hp and 480 Nm of torque, achieved through gentle soft charging with just 0, 3 bar (relative) boost, let the BMW M3 appear completely changed. Already from 3.000 rpm on the supercharged G-POWER M3 TORNADO pulls like the standard BMW M3 revving twice as much, but then the G-POWER M3 TORNADO really starts to flex its muscles: from 5.000 rpm on until redline the G-POWER M3 TORNADO provides constantly about 20 % more torque than the factory car, this provides an acceleration that feels like being dragged by a bungee cord.
This output explosion is based on the heart of the G-POWER supercharger system, the all new T1-518 ASA centrifugal supercharger. By the way the ASA superchargers are being used in the ALPINA models B5S, B6S and B7 as well, just like the ALPINA B6 GT3 race car, in which the chargers could state there impressive quality and reliability during 3.500 km in the “Green Hell” of the Nurburgring at the 24th hour race on may 23rd and 24th!
