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 E38 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 new found
power makes the E38 740 powerful enough
to overtake and accelerate hard with
the greatest ease. As a daily driver
the supercharged BMW 740 is a mild
mannered executive car waiting for
the throttle body to be flung open.
It is easy to slide the back out under
full throttle and send the 7 series
V8 to ridiculous speeds way above
the limit. Upgraded brakes are a suggested
pre-requisite.
The early 97/98 V8 single VANOS (variable
intake) M62 engines when supercharged
made approx 10-15 whp less throughout
the rpm range when compared to the
newer 98-01 double VANOS M62TU engines
but made almost identical peak power
and torque. This applied to both automatic
and manual transmission vehicles.
The BMW E38 740 houses the same configuration
M62 engine as the E39 540. VF-Engineering
performed all their M62 engine testing
on a '97 540 Auto and a '03 540 6-speed
Sport model owned by the head of R&D
at VF-Engineering. "The blown
V8 is one of my all time favorites.
It just eats the freeway when I roll-on
to full throttle at any speed."-
NS. The supercharged 740 has the looks
and refinements one expects from a
high-end BMW family car but is a true
autobahn terrorist to the unsuspecting
eye.
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.
All key components are 100% made
in California. 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 month's
software testing the BMW Bosch and
Siemens ECUs. 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 a bolt-on crank pulley
with an additional active OEM tensioner
using a dedicated serpentine belt.
The key to reliable superchargers
systems is the active belt tensioner
which eliminates belt slip. 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.
Every aspect of this kit has been
fully engineered for high quality
fitment and highly demanding performance
and expectation. VF's in-house horizontal,
turning and milling CNC's and plastic
molding plant, GIAC's industry reputation
and track record and Vortech's reliability
have been fully exploited to create
a product with internationally un-rivaled
material technology, quality and
performance.
Not all vehicles respond identically
to engine modifications which are
why it is important to consider
the "delta" or relative
power increase measured on the same
dyno before and after modification.
Power gains shown by VF have been
found to be accurate on test vehicles
on 91 octane at sea level, with
stock setups (i.e. throttle body,
exhaust system etc). The GIAC 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.
