This kit for your athletic Z4M covers everything you need to
seamlessly upgrade your power output in a linear and reliable
fashion: from A-to-Z.
VFs kit allows you to supercharge your M-Roadster or M-Coupe to
performance levels you never imagined! Add to the already superior
throttle response of the S54, with wild power gains thanks to
VFs enhanced ECU tuning, high quality parts, and the Vortech
centrifugal supercharger... and you get one hell of an explosive
package, but one that's also civil and reliable enough for daily
use by anyone. That's where the VF difference is apparent.
Maintaining the original BMW quality, smoothness and
reliability were the key factors in the VF
VF has harnessed the reliability of Vortech V-series superchargers.
With VF's 10 years of supercharging experience and worldwide OEM
supply contacts, they have created the ultimate supercharger system
for the ultimate driver's car....
In late 2004, VF began to develop S54 supercharger technology
and chose to create and test a complete aftercooled "Stage 1" kit,
from there things took off.
A production cast aluminum manifold with integrated air-to-water
heat exchanger (charge cooler) was custom developed for greater
performance and clean looks under the hood. The latest version
offers excelent performance as well as attractive esthetics.
Compared to similar air/air systems that are the common place
solution; VFs air-to-water system is definetaly more costly for
them to implement Typically used in professional Rally cars, and
chapion drag race vehicles; air/water cooling is the ultimate in
aftercooler technology for on and off the race track. VF does there
best to implement this reliable technology at no cost disadvantage
to you! Air/water cooling provides superior cooling ability over
air/air without lengthy ducting that can cause complex ECU and
tuning troubles and while creating a cooler intake temperatures for
more powerful and reliable ignition.
The end result ? A system that is very clean and simple in
its elegant installation and that the engine continues to drive and
feel like an "M Car" while offering much more power with similar
linear delivery, crucial to keep the cars excellent qualities
All key components are 100% made in California.
Supporting components such as flow matched injectors, radiators and
water pumps are all acquired from German OEMs. This system has been
fully road tested and dyno tuned on both the Mustang MD500AWD and
in-house Dynojet 224XLC dynamometers with and without engine load.
All stage 1 kits are setup at 6 psi and create as much, if not
more, power than similar products running greater levels of
VF 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. Testing the
software included extensive road and dyno test cycles, with
acceleration and deceleration tests for drivability 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 VF to fully explore the potential of the BMW engine, making
over 40% more power in most applications.
VF chooses the Vortech supercharger, mounting it
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.
Some facts about the VF kit versus the competition:
The VF supercharger system remains fully OBD2 compliant and is
supported by a 1 year unlimited mileage warranty (on the kit only).
Installation can be performed by most competent technicians in a
true 12-16 hours and is non-intrusive, allowing it to be fully
Drag racing and aggressive back to back peak rpm shifting with the
higher stage levels 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.

Not all vehicles respond identically to engine modifications
which is why it is important to consider the "delta", or relative
power increase, measured on the same dyno before and after
modifications. Power gains shown on the bolt on VF kits have have
been found to be accurate on test vehicles on 91 octane at sea
level. VF does not guarantee that all engines will make the same
power numbers. The custom software adapts just as the OEM software
and a slight increase in performance may be expected from the use
of higher quality fuels such as 93 octane. Power gains may vary
according to factors such as altitude or vehicle condition. VF
installs its systems in house as means of continuous product
monitoring. All vehicles are dyno'd pre-install and the stock E46
M3 typically delivers 265-275whp on 91 octane. VF-Engineering is
not responsible for pre-existing or consequential wear and tear of
your vehicle. It is an assumed owner responsibility to ensure your
car is adequately upgraded to support power enhancements.
VF's testing of EGT and wide band O2 was performed from sensors
installed in the OEM header. Technicians logged individual cylinder
exhaust gas temperatures as well as Air/Fuel ratio in each exhaust
bank (pre-catalytic converter).
