Dinan's Supercharger System
for the 540i delivers unparalleled acceleration, every-day drivability and
reliability enthusiasts have come to expect from Dinan tuned BMW.
Countless hours of development, refinement and testing have resulted in a
supercharged engine that produces 486.125 horsepower @ the Crank (388.9 horsepower @ the Rear
Wheel on Dyno Jet + 20% Power Loss: 388.9 HP divided by 80% = 486.125HP) and 421.25 lb/ft of torque @ the Crank
(337 lb/ft @ the Rear Wheel on Dyno Jet + 20% Power Loss: 337 lb/ft divided by 80% = 421.25 lb/ft Torque).
Yet behaves in a civilized manner. Close attention to detail
and the highest quality materials ensure that the fit and finish are
on par with factory standards.
Dinan's expertise in forced
induction engine technology is evident in every aspect of the 540
Supercharger System. The system employs Vortech's efficient and
reliable gear driven supercharger, featuring helical cut gears for quiet
operation. A wide, 8 rib belt ensures maximum reliability at the
speeds necessary to deliver 8 pounds of boost pressure. The engine
management systems have been programmed for maximum power gains,
drivability and compliance with applicable emissions standards.
Dinan software ensures that the system maintains all On Board Diagnostic
(OBD II) functions and that the ignition timing and air/fuel mixtures are
optimal throughout the engine's operating range. BMW's variable cam
timing system, "VANOS", has been reprogrammed for maximum power
gains and improved low-end torque. The system also features an
aggressive Cold Air Intake to ensure that the supercharged engine is
breathing plenty of cool, dense air for maximum power gains.
