When experiencing a VF Engineering
Supercharger, you’ll get the
power you need without breaking
the bank.
High
quality VF construction
VF-Engineering chose to supercharge
the BMW E46 M3 to add to an already
superior throttle response and give
wild mid-to-top end power (sport mode)
with the centrifugal Vortech supercharger.
Maintaining the the original BMW quality,
smoothness and reliability were the
key factors in the VF design. This
is where the GIAC software comes into
full play. VF have harnessed 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 drivers car.
VF purchased a 2005 model BMW E46
M3 and chose to create a complete
aftercooled stage 1 kit comprising
of a production manufactured aluminum
manifold with integrated air-to-water
heat exchanger (charge cooler). 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 and giving
cooler intake temperatures for more
powerful ignition.
VF has planned a (VHPD) Very High
Performance Derivative stage 2. Aimed
at the hard core enthusiast, this
upgrade from the stage 1 package will
include engine internal and lowered
compression components. The VF demo
car has been earmarked for conversion
to be a 100% race car to show off
this eventual flagship product.
All testing has been carried out on
91 octane Californian fuel and long
term testing is currently being conducted
in Summer 100+deg F temperatures.
All key components are 100% made in
California. Supporting components
such as injectors, radiators and water
pumps are all acquired from German
OEMs. This system has been fully road
tested and dyno tuned on both the
GIAC 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 boost.
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 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 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 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 VF
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
