Installation Services Installations at Rogue Engineering are
definitely atypical compared to "other" shops. Since
the work performed on vehicles represent how we would work on our own
cars, when installing a supercharger kit of this nature, we do not install
"by the hour" nor do we cut corners. We work on the vehicles until they have
completely satisfied our requirements, or it doesn't leave our
facility. Because of this obsessive nature, our typical install
requires the car to be in our facility at least 4-5 working days.
Please note that installation labor
prices quote by phone are for kits purchased directly from

All key components are 100% made
in California. Supporting components such as flow matched injectors,
radiators and water pumps are all aquired 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 kits are setup at 6 psi and create as much, if
not more, power than similar products running greater
levels of boost.
Software flash technology and latest BMW file versions have all been
employed to provide the cleanest and the most reliable method of software
installation. VF 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 12-14 hours and is non-intrusive, allowing it to be fully
Some other facts about the VF kit versus the competition:
The Vortech supercharger is a much larger unit and therefore has a
superior flow rate over the competition.
The Vortech unit [centrifugal] runs at approximately half the
impeller speed when compared to a typical planetary unit at
like-for-like boost levels.
The Vortech unit is capable of creating up to 20psi [application
dependent] and therefore has greater potential for higher power levels.
The Vortech unit does not need its own separate oil cooling system
with reservoir and extra radiator.
Vortech units have been on the market for over 15 years in the US,
many many times longer than the competition.
VF's air/water cooling system is far superior to any air/air
intercooler which is why VF makes 460whp on 91 octane without water/meth
VF's Stage2 makes the same power as the competitor kit but with less
boost and less octane. VF only needs 8psi and 91 octane.
No modifications to the bumper or under panel as all VF components
are designed to fit within the confines of the factory panels
With the basic details
and facts laid out as above, there is every reason to buy a VF kit for
your E46 M3.
need anything else? For those with stock cars,
nearly doubling the power on and M3 without consequence is not
realistic. Many customers quickly realize that the stock brakes are
not enough to haul the M3 down from speed. Some consider upgraded
pads, while most know that upgraded braking systems (such as a big brake kit) is required.
customers have elected to keep the stock exhaust manifolds and catalysts
with their Stage 2 upgrade during the initial installation. While
they are giving up some power, they give some time for their wallets to
recover to save up for the headers and catalysts to be installed later
down the road. No additional programming is required.
not required, suspension is also a huge improvement on the E46 M3 (with or
without the supercharger). Other upgrades such as 3.91 or 4.10
gear ratios also makes for an excellent improvement in drivability.
Lightweight flywheels with weights LESS than 10 pounds is not recommended,
as it has been shown to affect the vehicles ability to maintain a
consistent, factory-like idle and throttle response. We have more
success with stock or our F/I
- VF's test cars did not require the headers/cats to be upgraded for
stage 1. Adding an aftermarket header may not necessarily improve
engine performance but may become necessary due to, reduced life
expectancy of stock cats with increased power levels.
Pressure testing by VF engineers accross the cat and between the
cylinder head and cat has shown sufficiently low readings with upto
8psi of intake manifold pressure. Arduous or track driving may require
a clutch upgrade, but VF testing for stage 1 has been performed with
BMW stock clutch and the full stock exhaust system. Sports cats are
compatible providing that, the quality of the Cat material and cell
density is sufficiently high. Depending on the extent of wear, stock
cats may eventually need upgrading.
Update (12/23/07) Stage 2 testing has been carried out with
aftermarket headers and European OEM M3 catalytic convertors. VF is
not responsible for the reduced life expectancy of your stock
catalytic convertors. VF does not endorse altering the ECU diagnostics
and software to remove "Catalytic inefficiency" DTC codes
caused by certain aftermarket headers.
ECU tuning/recalibration with forced induction systems that retain the
Mass Air Flow (MAF) is extremely complex. VF retains the MAF in its
E46M3 systems and does not disconnect the MAF to operate the vehicle
in "speed density/safety" mode also know as
"Alpha-N". Disconnecting the MAF on the M3 will prevent the
ECU from seeing "real-time" air flow readings and the ECU
then relies on the Throttle Position Sensor for an interpolated value.
VF engineers went one step further by replacing the M3s MAF to a more
reliable Hitachi MAF. This MAF has a track record for reliability and
consistency in the aftermarket on upto 800hp systems. With real time
fuel trimming from MAF metering, the ECU calibration performed inhouse
by VF's software engineers allows the car to function as a stock vehicle would.

are highly recommended for all stages of power upgrades to allow the
driver to monitor max boost and air fuel ratio. Cold weather can yield
greater boost levels which can be dangerous - keep an eye on this by
installing a boost gauge. "Wide Open Throttle" air fuel
mixtures change based on the adaptation of the ECU. Use a "wide
band" dedicated oxygen sensor kit to monitor your air fuel
ratings play a large effect on the performance of your engine.
Always use minimum 91 octane. Where possible higher octanes will yield
greater power output and safer ignition. Race Track use exerts
increased load and demand on your engine. The use of 100 octane
minimum is recommended for track use.
about me? I have an convertible! We have supercharged a few E46 M3 convertibles with much
success. A point of concern is the inherit cowl shake in the
vehicle, and how it would be affected with nearly double the power.
Fortunately, by changing the suspension to a better performing system, the
vehicle not only rides better than stock, but the power of the
supercharger does not seem to affect the cowl shake as negatively as one
would believe. Have your cake, and eat it, too.
