VF-Engineering
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 new
found power makes the 740 powerful enough to overtake and accelerate hard with
the greatest 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 rediculous
speeds way above the limit. Uprated brakes and 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 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 an '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.
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 sytems is the 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.
