We chose to supercharge the BMW 3-series to improve throttle response and mid-to-top end power with the centrifugal Vortech supercharger. Maintaining the the original BMW quality, smoothness and reliability were the key factors in the design. This is where the GIAC software comes into full play.Harnessing reliability of Vortech superchargers and quality of GIAC custom software with their 10 years of supercharging experience and worldwide OEM supply contacts to create the ultimate supercharger system for the ultimate driver's car.

All key components are 100% made in California. This system has been fully road tested and dyno tuned on our DYNOJET 1500AWHP Dyno. All stage 1 kits are setup at 6 psi and create as much, if not more power than similar products running greater levels of boost.

Our engineers spent over 12 months software testing the BMW Bosch and Siemens ECUs and resolved “stalling and MAF issues” faced by other supercharger systems. Software flash technology and latest BMW file versions have all been employed to provide the cleanest and the most reliable method of software installation. GIAC engineers extensively re-wrote the ECU software using their own binary, assembly and disassembly algorithms written from scratch. Testing the software included extensive road and dyno test cycles, with acceleration and deceleration tests for driveability smoothness and ECU fuel management. All test cars were put through long term full throttle testing in conditions varying from wet cold climates to hot dry Arizona desert temperature for safe-optimal air fuel ratios and knock activity monitoring. Competently-written ECU software has allowed us to fully explore the potential of the BMW engine, making over 40% more power in most applications.

We chose to mount the Vortech supercharger with an in-house CNC machined aluminum bracket system. The unit is positioned in line with the original serpentine belt which is replaced with a longer OEM belt. The key to this design is that the OEM active-spring belt tensioner remains fully functional and eliminates belt slip or the need to manually tension the belt. The supercharger air ducts are custom molded in-house from plastic to give an OEM appearance, quality and fit. The incorporated Bosch boost overrun system is designed for smooth off-throttle cruising and deceleration with clean emissions. The crankcase ventilation system is designed to cope with positive pressure and high flow OEM injectors are supplied to fit as direct replacements without modification to the injector rail.  A removable plastic air box is provided with the K&N induction filter for those who use their vehicles in persistently wet climates. The supercharger system remains fully OBD2 compliant and is supported by a 3 year unlimited mileage warranty on the product only. Installation can be performed in approximately 8 hours and is non-intrusive, allowing it to be fully reversible.

We chose to supercharge the BMW E46 M3 to add to already superior throttle response and give wild mid-to-top end power (sport mode) with the centrifugal Vortech supercharger.

A production manufactured aluminum manifold with integrated air-to-water heat exchanger (charge cooler) is provided for added value and greater performance compared to similar air/air systems. Typically used in European Rally cars, air/water cooling is the ultimate in aftercooler technology for on and off the race track. Air/water cooling provides superior cooling ability over air/air without lengthy ducting while creating cooler intake temperatures for more powerful and reliable ignition.

The E46 M3 Stage 2 kit [released Feb 08] offers even greater performance via extra boost from a smaller supercharger pulley, replacement stiffer serpentine belt tensioner and upgraded GIAC stage 2 software ECU flash with larger stage2 fuel injectors and MAF upgrade. This kit requires the use of high performance cats. The test car was setup with Supersprint headers and Euro M3 cats. Drag racing and aggresive back to back peak rpm shifting will likely require a clutch upgrade. 100 octane fuel recommended when used on the race track. A pre-cat wideband air/fuel ratio monitoring gauge is recommended.

The Stage 3 test car has been setup with a compression lowering gasket and extra boost (11-12 psi) from a replacement crank pulley of increased diameter, upgraded GIAC stage 3 software ECU flash. There is no planned public release for the stage 3 until long term test results have been approved. Beta kits will be made available sometime in 08.

We chose to supercharge the BMW 525, 538 and 530 to improve throttle response and mid-to-top end power with the centrifugal Vortech supercharger. With the 3.0 liter version being a bored and stroked upgrade of the 2.8 motor, both variations are otherwise virtually identical. Maintaining the the original BMW quality, smoothness, and reliability were the key factors in the design. This is where the GIAC software comes into full play.

We chose to supercharge the BMW 540 to increase throttle response and mid-to-top end power with the centrifugal Vortech supercharger. With the stock 4.4 liter motor, power and torque are already substantial. However this upgrade is for the V8 enthusiast who demands more than substantial power. The newfound power makes the 540 more powerful than a stock E39 M5 in many areas of the rpm range. As a daily driver the supercharged 540 is a mild mannered beast waiting for the throttle body to to be flung open. It is easy to slide the back out under full throttle and send the 5 series V8 to speeds way above the limit in a split second. Good brakes and self control are suggested pre-requisites.

When supercharged, the early 96-98 V8 single VANOS (variable intake) M62 engines make approx 10-15 whp less throughout the RPM range when compared to the newer 98-03 double VANOS M62TU engines but make almost identical peak power and torque. This applies to both automatic and manual transmission vehicles.

We chose to supercharge the all-new BMW 650 to increase throttle response and mid-to-top end power with the centrifugal Vortech supercharger. With the stock 4.4 liter motor, power and torque are already substantial. However this upgrade is for the V8 enthusiast who demands more than substantial power. The new found power makes the 650 more powerful than a stock E64 M5 and a potential contender to the new E60 M5 V10. As a daily driver the supercharged 650 SMG is a mild mannered beast waiting for the throttle body to opened wide. It is easy to slide the back end out under full throttle and launch the V8 to speeds way above the limit in a split second. Good brakes and self control are suggested pre-requisites.

We aftercooled the 650 by integrating a chargecooler into a cast aluminum intake manifold included with the kit to replace the original manifold. This design approach reduces the length of pipework by about 75% required for a remote mounted chargecooler core or air/air intercooler. The simple and compact design make this kit integrate neatly into the V8's engine bay.

We chose to supercharge the BMW 740 to increase throttle response and mid-to-top end power with the centrifugal Vortech supercharger. With the stock 4.4 liter motor, power and torque are already suitable for the heavy 7 series chassis. However this upgrade is for the V8 enthusiast who demands more power. The newfound power makes the 740 powerful enough to overtake and accelerate hard with the greatest of ease. As a daily driver the supercharged 740 is a mild mannered executive car waiting for the throttle body to to be flung open. It is easy to slide the back out under full throttle and send the 7 series V8 to speeds way above the limit. Uprated brakes are a suggested pre-requisite.
